Title
MISP: Stored XSS via Inline-Served SVG Organisation Logos and Report Pictures
Summary
Affected versions of MISP serve uploaded SVG images inline without a restrictive browser sandbox.
The commit explains that SVG files are XML documents rather than passive bitmap images. While scripts inside SVG do not execute when the SVG is rendered through a normal <img>, they can execute when the SVG is navigated to directly or embedded as a document. In that case, malicious <script> elements, event handlers, or javascript: URLs execute on the MISP origin with the viewer’s session.
The affected use cases include:
- organisation SVG logos;
- event-report SVG pictures.
Importantly, the vulnerable behavior is on the serve path, not merely the upload path: the patch notes that a malicious SVG uploaded while SVG support was enabled could remain dangerous even after uploads were later disabled.

fix: [security] Sandbox inline-served SVG images | e2053fbcffe3… |
Fix summary
A new sandboxInlineFile() method is added to RestResponseComponent. When a file is served inline (download=false) and its type is SVG (svg, svgz, or image/svg+xml), the response is augmented with a Content-Security-Policy header containing the sandbox directive (which assigns an opaque origin and disables script execution, plugins, and form submission) along with restrictive default-src, style-src, img-src, and font-src directives that still permit rendering of inline styles, embedded raster images, and data: fonts. An X-Content-Type-Options: nosniff header is also set. The method is invoked from both the generic sendFile() path and the org-logo endpoint. The enable_svg_logos setting description is updated to warn administrators that SVG files remain XML documents and should be left disabled unless required.
Patch summary
Adds RestResponseComponent::sandboxInlineFile(CakeResponse, string) which checks the file type against a whitelist of SVG identifiers (svg, svgz, image/svg+xml, case-insensitive) and, on match, sets Content-Security-Policy: default-src 'none'; style-src 'unsafe-inline'; img-src 'self' data:; font-src data:; frame-ancestors 'self'; sandbox and X-Content-Type-Options: nosniff. Calls this method from sendFile() when download is false, and from OrganisationsController::getOrgLogo() after the file response is built. Updates the enable_svg_logos setting description in Server.php to reflect the sandboxing behaviour and advise leaving the setting disabled. Adds a new PHPUnit test file RestResponseSandboxInlineFileTest.php with cases covering SVG extension, MIME type, svgz, case-insensitivity, and confirmation that raster types (png, jpg, jpeg, gif, webp) and null/empty types receive no headers.
CVSS rationale
AV:N: The malicious SVG is delivered over HTTP/HTTPS to the victim's browser. AC:L: No race conditions or special network conditions are required; the SVG is already stored and served by the application. AT:N: No specific attack requirements beyond the SVG being present in the MISP instance. PR:L: The attacker needs an authenticated MISP account with permission to upload an organisation logo or attach a report picture. UI:P: The victim must navigate to the SVG URL or have it loaded in an <object>/<iframe> context; it does not execute when rendered via <img>. VC/VI/VA:N: The MISP server itself is not compromised; the impact is on the client-side session. SC:H: The attacker gains full read access to the victim's MISP session (threat intelligence, events, users, settings). SI:H: The attacker can perform write operations (create/modify/delete events, change settings) as the victim. SA:N: No availability impact on the victim's browser or the MISP instance.
Weakness rationale
- CWE-79 The core issue is that user-supplied SVG content (an XML document capable of embedding script) is served inline on the application origin without any mechanism to prevent script execution, resulting in stored XSS. The fix neutralises the script-execution capability via a sandboxing CSP.
- CWE-693 The upload-time restriction (enable_svg_logos) was the only protection, and it was insufficient because (a) it could be toggled off after files were already stored, and (b) it did not address the serve path at all. The serve path lacked its own protection mechanism (sandboxing CSP), which is what the patch adds.
Assumptions to verify
- The enable_svg_logos setting must be enabled (or was previously enabled and SVG files were uploaded) for the vulnerability to be exploitable; the default value is false.
- The attacker requires an authenticated MISP account with sufficient privileges to upload an organisation logo or attach a report picture.
- The victim must be an authenticated MISP user whose session is active in the browser when the SVG is loaded as a document.
- The fix is included in MISP v2.5.46 based on the tag boundary metadata (186 commits after the fix commit up to that tag); the exact version in which the vulnerability was introduced is not specified in the patch.
- CVSS UI:P assumes the primary exploitation path requires the victim to navigate to the SVG URL or have it embedded in an object/iframe; if an attacker can embed the SVG in a page the victim is already viewing without additional interaction, UI:N would apply.

Title
LaraDashboard 0.9.0 through 1.2.2 Stored XSS via SVG Upload
Summary
LaraDashboard versions 0.9.0 through 1.2.2 fail to sanitize SVG file content during media upload, allowing authenticated users with only the media.create permission to upload malicious SVG files containing script tags. When any user including administrators opens the stored SVG file served inline from the application origin, the embedded JavaScript executes in the dashboard context, enabling session hijacking and administrative account takeover.

5.4 (Medium)

Title
WP Recipe Maker <= 10.8.1 - Authenticated (Contributor+) Stored Cross-Site Scripting via 'notes' Parameter via REST Preview Endpoint
Summary
The WP Recipe Maker plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'notes' parameter in all versions up to, and including, 10.8.1 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with Contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.

Mitigation MIT-4
Architecture and Design
Strategy: Libraries or Frameworks
- Use a vetted library or framework that does not allow this weakness to occur or provides constructs that make this weakness easier to avoid [REF-1482].
- Examples of libraries and frameworks that make it easier to generate properly encoded output include Microsoft's Anti-XSS library, the OWASP ESAPI Encoding module, and Apache Wicket.
Mitigation
Implementation
Architecture and Design
- Understand the context in which your data will be used and the encoding that will be expected. This is especially important when transmitting data between different components, or when generating outputs that can contain multiple encodings at the same time, such as web pages or multi-part mail messages. Study all expected communication protocols and data representations to determine the required encoding strategies.
- For any data that will be output to another web page, especially any data that was received from external inputs, use the appropriate encoding on all non-alphanumeric characters.
- Parts of the same output document may require different encodings, which will vary depending on whether the output is in the:
- etc. Note that HTML Entity Encoding is only appropriate for the HTML body.
- Consult the XSS Prevention Cheat Sheet [REF-724] for more details on the types of encoding and escaping that are needed.
- HTML body
- Element attributes (such as src="XYZ")
- URIs
- JavaScript sections
- Cascading Style Sheets and style property
Mitigation MIT-6
Architecture and Design
Implementation
Strategy: Attack Surface Reduction
Understand all the potential areas where untrusted inputs can enter your software: parameters or arguments, cookies, anything read from the network, environment variables, reverse DNS lookups, query results, request headers, URL components, e-mail, files, filenames, databases, and any external systems that provide data to the application. Remember that such inputs may be obtained indirectly through API calls.
Mitigation MIT-15
Architecture and Design
For any security checks that are performed on the client side, ensure that these checks are duplicated on the server side, in order to avoid CWE-602. Attackers can bypass the client-side checks by modifying values after the checks have been performed, or by changing the client to remove the client-side checks entirely. Then, these modified values would be submitted to the server.
Mitigation MIT-27
Architecture and Design
Strategy: Parameterization
If available, use structured mechanisms that automatically enforce the separation between data and code. These mechanisms may be able to provide the relevant quoting, encoding, and validation automatically, instead of relying on the developer to provide this capability at every point where output is generated.
Mitigation MIT-30.1
Implementation
Strategy: Output Encoding
- Use and specify an output encoding that can be handled by the downstream component that is reading the output. Common encodings include ISO-8859-1, UTF-7, and UTF-8. When an encoding is not specified, a downstream component may choose a different encoding, either by assuming a default encoding or automatically inferring which encoding is being used, which can be erroneous. When the encodings are inconsistent, the downstream component might treat some character or byte sequences as special, even if they are not special in the original encoding. Attackers might then be able to exploit this discrepancy and conduct injection attacks; they even might be able to bypass protection mechanisms that assume the original encoding is also being used by the downstream component.
- The problem of inconsistent output encodings often arises in web pages. If an encoding is not specified in an HTTP header, web browsers often guess about which encoding is being used. This can open up the browser to subtle XSS attacks.
Mitigation MIT-43
Implementation
With Struts, write all data from form beans with the bean's filter attribute set to true.
Mitigation MIT-31
Implementation
Strategy: Attack Surface Reduction
To help mitigate XSS attacks against the user's session cookie, set the session cookie to be HttpOnly. In browsers that support the HttpOnly feature (such as more recent versions of Internet Explorer and Firefox), this attribute can prevent the user's session cookie from being accessible to malicious client-side scripts that use document.cookie. This is not a complete solution, since HttpOnly is not supported by all browsers. More importantly, XmlHttpRequest and other powerful browser technologies provide read access to HTTP headers, including the Set-Cookie header in which the HttpOnly flag is set.
Mitigation MIT-5
Implementation
Strategy: Input Validation
- Assume all input is malicious. Use an "accept known good" input validation strategy, i.e., use a list of acceptable inputs that strictly conform to specifications. Reject any input that does not strictly conform to specifications, or transform it into something that does.
- When performing input validation, consider all potentially relevant properties, including length, type of input, the full range of acceptable values, missing or extra inputs, syntax, consistency across related fields, and conformance to business rules. As an example of business rule logic, "boat" may be syntactically valid because it only contains alphanumeric characters, but it is not valid if the input is only expected to contain colors such as "red" or "blue."
- Do not rely exclusively on looking for malicious or malformed inputs. This is likely to miss at least one undesirable input, especially if the code's environment changes. This can give attackers enough room to bypass the intended validation. However, denylists can be useful for detecting potential attacks or determining which inputs are so malformed that they should be rejected outright.
- When dynamically constructing web pages, use stringent allowlists that limit the character set based on the expected value of the parameter in the request. All input should be validated and cleansed, not just parameters that the user is supposed to specify, but all data in the request, including hidden fields, cookies, headers, the URL itself, and so forth. A common mistake that leads to continuing XSS vulnerabilities is to validate only fields that are expected to be redisplayed by the site. It is common to see data from the request that is reflected by the application server or the application that the development team did not anticipate. Also, a field that is not currently reflected may be used by a future developer. Therefore, validating ALL parts of the HTTP request is recommended.
- Note that proper output encoding, escaping, and quoting is the most effective solution for preventing XSS, although input validation may provide some defense-in-depth. This is because it effectively limits what will appear in output. Input validation will not always prevent XSS, especially if you are required to support free-form text fields that could contain arbitrary characters. For example, in a chat application, the heart emoticon ("<3") would likely pass the validation step, since it is commonly used. However, it cannot be directly inserted into the web page because it contains the "<" character, which would need to be escaped or otherwise handled. In this case, stripping the "<" might reduce the risk of XSS, but it would produce incorrect behavior because the emoticon would not be recorded. This might seem to be a minor inconvenience, but it would be more important in a mathematical forum that wants to represent inequalities.
- Even if you make a mistake in your validation (such as forgetting one out of 100 input fields), appropriate encoding is still likely to protect you from injection-based attacks. As long as it is not done in isolation, input validation is still a useful technique, since it may significantly reduce your attack surface, allow you to detect some attacks, and provide other security benefits that proper encoding does not address.
- Ensure that you perform input validation at well-defined interfaces within the application. This will help protect the application even if a component is reused or moved elsewhere.
Mitigation MIT-21
Architecture and Design
Strategy: Enforcement by Conversion
When the set of acceptable objects, such as filenames or URLs, is limited or known, create a mapping from a set of fixed input values (such as numeric IDs) to the actual filenames or URLs, and reject all other inputs.
Mitigation MIT-29
Operation
Strategy: Firewall
Use an application firewall that can detect attacks against this weakness. It can be beneficial in cases in which the code cannot be fixed (because it is controlled by a third party), as an emergency prevention measure while more comprehensive software assurance measures are applied, or to provide defense in depth [REF-1481].
Mitigation MIT-16
Operation
Implementation
Strategy: Environment Hardening
When using PHP, configure the application so that it does not use register_globals. During implementation, develop the application so that it does not rely on this feature, but be wary of implementing a register_globals emulation that is subject to weaknesses such as CWE-95, CWE-621, and similar issues.
CAPEC-209: XSS Using MIME Type Mismatch
An adversary creates a file with scripting content but where the specified MIME type of the file is such that scripting is not expected. The adversary tricks the victim into accessing a URL that responds with the script file. Some browsers will detect that the specified MIME type of the file does not match the actual type of its content and will automatically switch to using an interpreter for the real content type. If the browser does not invoke script filters before doing this, the adversary's script may run on the target unsanitized, possibly revealing the victim's cookies or executing arbitrary script in their browser.
CAPEC-588: DOM-Based XSS
This type of attack is a form of Cross-Site Scripting (XSS) where a malicious script is inserted into the client-side HTML being parsed by a web browser. Content served by a vulnerable web application includes script code used to manipulate the Document Object Model (DOM). This script code either does not properly validate input, or does not perform proper output encoding, thus creating an opportunity for an adversary to inject a malicious script launch a XSS attack. A key distinction between other XSS attacks and DOM-based attacks is that in other XSS attacks, the malicious script runs when the vulnerable web page is initially loaded, while a DOM-based attack executes sometime after the page loads. Another distinction of DOM-based attacks is that in some cases, the malicious script is never sent to the vulnerable web server at all. An attack like this is guaranteed to bypass any server-side filtering attempts to protect users.
CAPEC-591: Reflected XSS
This type of attack is a form of Cross-Site Scripting (XSS) where a malicious script is "reflected" off a vulnerable web application and then executed by a victim's browser. The process starts with an adversary delivering a malicious script to a victim and convincing the victim to send the script to the vulnerable web application.
CAPEC-592: Stored XSS
An adversary utilizes a form of Cross-site Scripting (XSS) where a malicious script is persistently "stored" within the data storage of a vulnerable web application as valid input.
CAPEC-63: Cross-Site Scripting (XSS)
An adversary embeds malicious scripts in content that will be served to web browsers. The goal of the attack is for the target software, the client-side browser, to execute the script with the users' privilege level. An attack of this type exploits a programs' vulnerabilities that are brought on by allowing remote hosts to execute code and scripts. Web browsers, for example, have some simple security controls in place, but if a remote attacker is allowed to execute scripts (through injecting them in to user-generated content like bulletin boards) then these controls may be bypassed. Further, these attacks are very difficult for an end user to detect.
CAPEC-85: AJAX Footprinting
This attack utilizes the frequent client-server roundtrips in Ajax conversation to scan a system. While Ajax does not open up new vulnerabilities per se, it does optimize them from an attacker point of view. A common first step for an attacker is to footprint the target environment to understand what attacks will work. Since footprinting relies on enumeration, the conversational pattern of rapid, multiple requests and responses that are typical in Ajax applications enable an attacker to look for many vulnerabilities, well-known ports, network locations and so on. The knowledge gained through Ajax fingerprinting can be used to support other attacks, such as XSS.
