CWE-918

Allowed

Server-Side Request Forgery (SSRF)

Abstraction: Base · Status: Incomplete

API response cwe.mitre.org

Title
Budibase backend-core SSRF via incomplete default blacklist
Summary
Budibase backend-core (@budibase/backend-core, as used by @budibase/server) omits the shared address space range 100.64.0.0/10 from its default SSRF blacklist (DEFAULT_BLACKLIST) used by REST datasource query previews. When the default blacklist is active (i.e., a self-hosted deployment has not defined BLACKLIST_IPS), an authenticated user with the Builder permission can submit a REST datasource query preview request to POST /api/queries/preview targeting a reachable HTTP(S) service in the 100.64.0.0/10 range, causing the server to send a request to that target and return its response through the preview flow. Per the advisory, no released fix was identified at the time of publication; remediation is to add 100.64.0.0/10 to DEFAULT_BLACKLIST.

CVE-2026-82234 (GCVE-0-2026-82234)

Vulnerability from cvelistv5 – Published: 2026-08-28 10:49 – Updated: 2026-08-28 16:10

Title
SiYuan before v3.8.1 SSRF via DNS-Rebinding TOCTOU
Summary
SiYuan versions before v3.8.1 contain a server-side request forgery vulnerability in the http_request and web_fetch agent tools that perform DNS resolution only at guard time without validating the connect-time resolution. Attackers can use DNS rebinding to answer the guard resolution with a public IP and the connect resolution with a private or metadata IP, bypassing the SSRF defense to access cloud instance metadata and internal services.

CVE-2026-82044 (GCVE-0-2026-82044)

Vulnerability from cvelistv5 – Published: 2026-10-02 20:20 – Updated: 2026-10-05 17:13 X_Open Source
VLAI
Title
UTMStack < 11.2.16 Server-Side Request Forgery via downloadPdf
Summary
UTMStack before 11.2.16 contains a server-side request forgery vulnerability that allows authenticated attackers to make the server request arbitrary internal resources by supplying an unvalidated url parameter to the PdfService.downloadPdf() method exposed via GET /api/generate-pdf-report. Attackers can leverage this to force the web-pdf microservice to fetch internal backend endpoints, the OpenSearch cluster, or the cloud instance-metadata service, exposing sensitive internal data rendered into the returned PDF.

Title
UTMStack < 11.2.16 SSRF via IdentityProviderService
Summary
UTMStack before 11.2.16 contains a server-side request forgery vulnerability in IdentityProviderService.validateMetadataUrl() that allows authenticated attackers to make the server send requests to arbitrary internal or cloud metadata hosts by supplying a malicious metadata URL to the identity-providers endpoint. Attackers can exploit the POST/PUT /api/identity-providers endpoint with no validation of target host, IP, or scheme to perform internal network port scanning and access cloud instance-metadata services.

Title
elFinder: SSRF protection bypass via DNS rebinding in the `fsock_get_contents()` fallback
Summary
elFinder is an open-source file manager for web, written in JavaScript using jQuery UI. Prior to 2.1.70, elFinder URL uploads in php/elFinder.class.php can bypass server-side request forgery protections when PHP cURL is unavailable because validate_address() validates $info['ip'], but get_remote_contents() selects fsock_get_contents(), which connects to $arr['host'] and performs a second DNS resolution. An attacker able to submit a URL upload can use DNS rebinding to have the first resolution return a public address and the connection resolution return a loopback or private address, causing the internal HTTP response body to be stored as an uploaded file and made readable through elFinder. After a successful fetch, get_headers($url, true) separately requests the original hostname without reusing the validated and pinned connection, creating an additional blind server-side request forgery path even when curl_get_contents() is selected. This issue is fixed in version 2.1.70.

CAPEC-664: Server Side Request Forgery

An adversary exploits improper input validation by submitting maliciously crafted input to a target application running on a server, with the goal of forcing the server to make a request either to itself, to web services running in the server’s internal network, or to external third parties. If successful, the adversary’s request will be made with the server’s privilege level, bypassing its authentication controls. This ultimately allows the adversary to access sensitive data, execute commands on the server’s network, and make external requests with the stolen identity of the server. Server Side Request Forgery attacks differ from Cross Site Request Forgery attacks in that they target the server itself, whereas CSRF attacks exploit an insecure user authentication mechanism to perform unauthorized actions on the user's behalf.
