CWE-918

Allowed

Server-Side Request Forgery (SSRF)

Abstraction: Base · Status: Incomplete

API response cwe.mitre.org

The web server receives a URL or similar request from an upstream component and retrieves the contents of this URL, but it does not sufficiently ensure that the request is being sent to the expected destination.

3206 vulnerabilities reference this CWE, most recent first.

Title
Server-Side Request Forgery via Favicon Redirect to Local Network Resources in PlaywrightCapture
Summary
PlaywrightCapture contains a server-side request forgery (SSRF) vulnerability in its favicon retrieval functionality. When only_global_lookup is enabled, the application validates the initial favicon URL to prevent requests to localhost, loopback, or other non-public network addresses. However, redirects followed by aiohttp were not subjected to the same validation. An attacker able to influence the content of a page processed by PlaywrightCapture could specify a publicly reachable favicon URL that responds with an HTTP redirect to a local or otherwise restricted address, such as 127.0.0.1, localhost, or an internal network service. Because aiohttp automatically followed the redirect, the resulting request could bypass the application's local-address restrictions and cause the PlaywrightCapture host to issue HTTP requests to resources that should not be externally reachable. Depending on the services reachable from the PlaywrightCapture host and how retrieved favicon data is subsequently exposed or processed, this could be used to probe internal HTTP services or potentially obtain information from otherwise inaccessible endpoints. The patch introduces an aiohttp request middleware that applies the existing local-URL validation to every request in the redirect chain. Requests resolving to restricted/local destinations are rejected before they are issued.

Title
Ollama 0.30.0 through 0.33.2 SSRF via Cross-Host Tensor Blob Redirect
Summary
Ollama fails to validate redirect destinations when pulling tensor-layer models, allowing unauthenticated attackers to redirect blob downloads to arbitrary hosts. An attacker can control a registry, serve a malicious tensor-layer manifest, and cause the server to issue GET requests to internal hosts including cloud metadata endpoints.

Title
Label Studio through 1.23.0 SSRF via Unvalidated Webhook URL
Summary
Label Studio through 1.23.0 fails to validate webhook URLs, allowing authenticated users to dispatch requests to internal services including RFC 1918 addresses and cloud metadata endpoints. Attackers can create webhooks targeting private networks and exfiltrate annotation data by enabling payload transmission in outbound requests.

CVE-2026-85172 (GCVE-0-2026-85172)

Title
n8n before 2.34.1 SSRF via Request Helper URI Validation Bypass
Summary
n8n versions before 2.34.1 contain a server-side request forgery vulnerability in the legacy request helper function exposed to Code and Function nodes. The validation logic checks the uri property for SSRF safety while the underlying HTTP client uses the url property when both are present, allowing attackers to bypass validation by supplying a safe uri alongside a malicious url to access internal addresses.

CVE-2026-84721 (GCVE-0-2026-84721)

Title
Automation-controller: automation-controller: email notification backend allows ssrf via user-controlled smtp host/port (internal port-scan oracle, smtp password exfil)
Summary
A server-side request forgery flaw was found in the Ansible Automation Platform automation-controller email notification backend. The email backend passes the user-supplied SMTP host and port from a notification template directly to the SMTP client without validating that the target is not an internal, loopback, link-local, or reserved address. An authenticated user with organization notification-admin permission can create or modify an email notification template pointing at an arbitrary internal address, trigger a test, and have the controller task process open a raw TCP connection to that address. The resulting connection error is reflected back through the notification record, providing a three-state internal port-scan oracle (open, closed, filtered) over the control-plane's cluster network, including the in-cluster Kubernetes API. When a shared organization template holds a stored SMTP password, redirecting the host can also cause that credential to be transmitted to an attacker-controlled server.

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.
