CVE-2026-13165 (GCVE-0-2026-13165)

Vulnerability from cvelistv5 – Published: 2026-06-29 12:16 – Updated: 2026-06-29 13:58
VLAI
Title
Remote Code Execution in SzafirHost
Summary
SzafirHost verifies the downloaded native library archive with one JarFile parser (reading the Central Directory) but extracts native libraries with JarInputStream parser (reading sequentially from local file headers). An attacker who controls the served archive can insert a malicious DLL/SO/DYLIB as a local-file-header entry between the last legitimate entry and the Central Directory, without adding it to the Central Directory. The signature verifier never sees the injected entry and accepts the archive as validly signed; the extractor reads it sequentially and writes the attacker library to the native temp directory with no hash check), while the archive-size check still passes. This can lead to remote code execution. This issue was fixed in version 1.2.2.

Title
LearnDash LMS <= 5.1.5 - Authenticated (Subscriber+) Arbitrary File Upload via Assignment Upload Handler
Summary
The LearnDash LMS plugin for WordPress is vulnerable to Unrestricted File Type Upload in versions up to and including 5.1.5. This is due to insufficient input validation in the 'learndash_fileupload_process' function, which iterates through an entire array and validates only the first file. This makes it possible for authenticated attackers, with subscriber-level access and above who are enrolled in a course with assignment uploads enabled, to upload arbitrary disallowed files, including PHP files, to the server's wp-content/uploads/learndash/assignments/ directory. The uploaded files can only be used for Remote Code Execution if default server configurations have been changed to allow for execution.

Title
Easy Digital Downloads <= 3.6.9 - Authenticated (Shop Manager+) Arbitrary File Upload via 'edd-import-file' Parameter
Summary
The Easy Digital Downloads plugin for WordPress is vulnerable to Arbitrary File Upload in versions up to and including 3.6.9. This is due to insufficient file type validation in the edd_do_ajax_import_file_upload() function , which only checks the client-supplied $_FILES['edd-import-file']['type'] Content-Type header against an allow-list of CSV mime types, then uses raw move_uploaded_file() (bypassing wp_handle_upload()'s core MIME enforcement) to write the file under its original extension into the web-accessible wp-content/uploads/edd/exports/ directory. This makes it possible for authenticated attackers, with Shop Manager-level access and above, to upload arbitrary files on the affected site's server which may make remote code execution possible.

Title
OTP Login & Register Woocommerce <= 2.7.2 - Unauthenticated Authentication Bypass via Brute Force
Summary
The OTP Login & Register Woocommerce plugin for WordPress is vulnerable to Authentication Bypass via OTP Brute Force in all versions up to, and including, 2.7.2. The vulnerability exists because the OTP rate-limit attempt counter in `process_otp_form` is keyed exclusively on the attacker-controlled `xoo_ml_user_ip_data` cookie's `ip_address` field, allowing unlimited counter resets by simply rotating the cookie, while the OTP itself is generated with PHP's non-cryptographic `rand()` function over a default space of only 9,000 possible values (1000–9999), and both the OTP issuance endpoint (`xoo_ml_login_with_otp`) and verification endpoint (`xoo_ml_otp_form_submit`) are registered as unauthenticated `wp_ajax_nopriv` actions with no nonce or capability checks. This makes it possible for unauthenticated attackers to brute-force the OTP for any registered account and obtain a full WordPress authentication session — including for administrator accounts — via `wp_set_auth_cookie()` in `login_user_with_otp()`. Exploitation requires the attacker to know the target user's registered phone number, which is used to trigger OTP issuance via the unauthenticated `xoo_ml_login_with_otp` endpoint.

The vulnerability exists because the OTP rate-limit attempt counter in `process_otp_form` is keyed exclusively on the attacker-controlled `xoo_ml_user_ip_data` cookie\u0027s `ip_address` field, allowing unlimited counter resets by simply rotating the cookie, while the OTP itself is generated with PHP\u0027s non-cryptographic `rand()` function over a default space of only 9,000 possible values (1000\u20139999), and both the OTP issuance endpoint (`xoo_ml_login_with_otp`) and verification endpoint (`xoo_ml_otp_form_submit`) are registered as unauthenticated `wp_ajax_nopriv` actions with no nonce or capability checks. This makes it possible for unauthenticated attackers to brute-force the OTP for any registered account and obtain a full WordPress authentication session \u2014 including for administrator accounts \u2014 via `wp_set_auth_cookie()` in `login_user_with_otp()`. Exploitation requires the attacker to know the target user\u0027s registered phone number, which is used to trigger OTP issuance via the unauthenticated `xoo_ml_login_with_otp` endpoint."

Mitigation
Architecture and Design

Generate a new, unique filename for an uploaded file instead of using the user-supplied filename, so that no external input is used at all.[REF-422] [REF-423]

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
Architecture and Design

Consider storing the uploaded files outside of the web document root entirely. Then, use other mechanisms to deliver the files dynamically. [REF-423]

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.
  • For example, limiting filenames to alphanumeric characters can help to restrict the introduction of unintended file extensions.
Mitigation
Architecture and Design

Define a very limited set of allowable extensions and only generate filenames that end in these extensions. Consider the possibility of XSS (CWE-79) before allowing .html or .htm file types.

Mitigation
Implementation

Strategy: Input Validation

Ensure that only one extension is used in the filename. Some web servers, including some versions of Apache, may process files based on inner extensions so that "filename.php.gif" is fed to the PHP interpreter.[REF-422] [REF-423]

Mitigation
Implementation

When running on a web server that supports case-insensitive filenames, perform case-insensitive evaluations of the extensions that are provided.

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
Implementation

Do not rely exclusively on sanity checks of file contents to ensure that the file is of the expected type and size. It may be possible for an attacker to hide code in some file segments that will still be executed by the server. For example, GIF images may contain a free-form comments field.

Mitigation
Implementation

Do not rely exclusively on the MIME content type or filename attribute when determining how to render a file. Validating the MIME content type and ensuring that it matches the extension is only a partial solution.

Mitigation MIT-17
Architecture and Design Operation

Strategy: Environment Hardening

Run your code using the lowest privileges that are required to accomplish the necessary tasks [REF-76]. If possible, create isolated accounts with limited privileges that are only used for a single task. That way, a successful attack will not immediately give the attacker access to the rest of the software or its environment. For example, database applications rarely need to run as the database administrator, especially in day-to-day operations.

Mitigation MIT-22
Architecture and Design Operation

Strategy: Sandbox or Jail

  • Run the code in a "jail" or similar sandbox environment that enforces strict boundaries between the process and the operating system. This may effectively restrict which files can be accessed in a particular directory or which commands can be executed by the software.
  • OS-level examples include the Unix chroot jail, AppArmor, and SELinux. In general, managed code may provide some protection. For example, java.io.FilePermission in the Java SecurityManager allows the software to specify restrictions on file operations.
  • This may not be a feasible solution, and it only limits the impact to the operating system; the rest of the application may still be subject to compromise.
  • Be careful to avoid CWE-243 and other weaknesses related to jails.
CAPEC-1: Accessing Functionality Not Properly Constrained by ACLs

In applications, particularly web applications, access to functionality is mitigated by an authorization framework. This framework maps Access Control Lists (ACLs) to elements of the application's functionality; particularly URL's for web apps. In the case that the administrator failed to specify an ACL for a particular element, an attacker may be able to access it with impunity. An attacker with the ability to access functionality not properly constrained by ACLs can obtain sensitive information and possibly compromise the entire application. Such an attacker can access resources that must be available only to users at a higher privilege level, can access management sections of the application, or can run queries for data that they otherwise not supposed to.
