Allowed

Server-Side Request Forgery (SSRF)

Title
mcp-webresearch Server-Side Request Forgery in visit_page Due to Missing Internal-IP Filtering
Summary
mcp-webresearch 0.1.7 contains a server-side request forgery vulnerability that allows attackers to access internal network services by supplying loopback, link-local, or cloud metadata addresses to the visit_page tool, which only validates the URL protocol without filtering private or reserved IP ranges. Attackers can steer the LLM-controlled URL argument through prompt injection to navigate the server's Playwright browser to internal endpoints such as cloud instance metadata services, causing the server to return sensitive internal page content including credentials into the model context.

Title
Server-Side Request Forgery in ATutor
Summary
ATutor is vulnerable to Server-Side request forgery in import functionalities. An authenticated administrator can make the server request arbitrary internal HTTP endpoints, cloud metadata services, or local files via file:// if the PHP environment permits URL wrappers. Product is no longer actively supported and the vulnerabilities have not been fixed. Only version 2.2.4 was tested and confirmed as vulnerable, other versions were not tested but might also be vulnerable.

Title
MaxKB: UpdateStoreTool fetches caller-supplied app-store URLs without host validation
Summary
MaxKB is an open-source AI assistant for enterprise. In versions 2.0.0 through 2.10.4-lts, UpdateStoreTool.update_tool passes caller-supplied download_url and download_callback_url values to requests.get without equivalent trusted-host and redirect validation, allowing an authenticated workspace user to make the server request internal, loopback, link-local, or cloud metadata URLs. A fix is present on the v2 branch but has not yet been included in a published release.

CVE-2026-64849 (GCVE-0-2026-64849)

Vulnerability from cvelistv5 – Published: 2026-08-17 21:16 – Updated: 2026-08-20 18:38

Title
MLflow: Unauthenticated full-read SSRF in webhook delivery: _validate_webhook_url bypassed via unvalidated HTTP redirects (and DNS rebinding)
Summary
MLflow is an open source AI engineering platform for agents, large language models, and machine learning models. Prior to 3.15.0, the unauthenticated POST /api/2.0/mlflow/webhooks/{id}/test endpoint calls _validate_webhook_url() in mlflow/utils/validation.py only for the original URL while mlflow/webhooks/delivery.py follows redirects and re-resolves the hostname without pinning the validated address, allowing attackers to reach internal or cloud metadata services and receive response_status and response_body. This issue is fixed in version 3.15.0.

Title
Next.js: Server-Side Request Forgery in Server Actions on Custom Servers
Summary
Next.js is a React framework for building full-stack web applications. In versions 14.1.1 through 15.5.20 and 16.0.0 through 16.2.10, when a Server Action forwards or redirects a request, an attacker can cause the server to send that outbound request to a malicious host (Server-Side Request Forgery). This requires the attacker's request to control Host-associated headers. In some configurations, it's also possible to obtain internal values that weaken middleware/proxy authorization. Applications that use Server Actions are affected when the incoming host header is not fixed to a trusted value. This typically occurs on custom servers, or on deployments not behind a proxy that pins the host. Managed hosting pins the host upstream and is not affected; next start and standalone output do the same from version 14.2 onward. This issue has been fixed in versions 15.5.21 and 16.2.11.

CVE-2026-64645 (GCVE-0-2026-64645)

Vulnerability from cvelistv5 – Published: 2026-07-27 17:37 – Updated: 2026-07-28 14:02

Title
Next.js: Server-Side Request Forgery in rewrites via attacker-controlled destination hostname
Summary
Next.js is a React framework for building full-stack web applications. In versions 12.0.0 through 15.5.20 and 16.0.0 through 16.2.10, a rewrites() or redirects() rule that builds its external destination hostname from request-controlled input can be pointed at an arbitrary hostname, regardless of the rule's hostname suffix. For a rewrite, Next.js proxies the request to that arbitrary host and serves the response from the application's origin, leading to Server-Side Request forgery. A redirects() rule configured this way is vulnerable to an Open Redirect. This issue has been fixed in versions 15.5.21 and 16.2.11.

CVE-2026-64626 (GCVE-0-2026-64626)

Title
AVideo Encoder downloadURL SSRF via unpinned retry fallback
Summary
AVideo versions from commit 0dbadbca through latest master contain a server-side request forgery vulnerability in the encoder download-by-URL flow due to an unpinned retry fallback that bypasses DNS pinning validation. An authenticated attacker can supply a downloadURL that redirects to an internal address, causing the unpinned retry to follow the redirect and reach internal targets for blind SSRF attacks.

Title
Huginn 2022.08.18 SSRF via ScenarioImport fetch_url Method
Summary
Huginn through 2022.08.18 contains a server-side request forgery vulnerability in the fetch_url method of ScenarioImport that allows authenticated users to make arbitrary HTTP requests by submitting crafted URLs. Attackers can probe internal network services, enumerate ports via error signatures, and access cloud metadata endpoints to retrieve sensitive credentials.

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.
