Title
Contao: Server-Side Request Forgery (SSRF) via Unvalidated RSS Feed URL in Feed Reader Module
Summary
Contao is an Open Source CMS. From 5.3.35 through 5.3.47 and from 5.7.0-RC1 through 5.7.8, the Feed Reader front-end module passes configured RSS feed URLs from FeedReaderController::getResponse() to feedIo->read() without scheme or private-address validation, allowing a backend user with module-edit permissions to make the server request internal network services, loopback addresses, or cloud metadata endpoints. In core-bundle/src/Controller/FrontendModule/FeedReaderController.php, the getResponse() function iterates over the configured feed URLs and passes each one directly to the HTTP client (via $this->feedIo->read($url, new Feed())) with no validation, while the DCA field definition for rss_feed in tl_module.php carries no URL scheme or host validation and the HTTP client is wired as @psr18.http_client (Symfony HttpClient) with no SSRF protection configured, since NoPrivateNetworkHttpClient is not used. This issue is fixed in versions 5.3.48.

CVE-2026-57211 (GCVE-0-2026-57211)

Title
RabbitMQ: UNC SSRF affecting the management UI on Windows
Summary
RabbitMQ is a messaging and streaming broker. Prior to 4.1.11 and 4.2.6 on Windows, the RabbitMQ management plugin static file handler rabbit_mgmt_wm_static can pass URL-encoded backslashes to erl_prim_loader:read_file_info before path validation when multiple management extension plugins are enabled, causing outbound DNS and SMB requests to attacker-controlled UNC paths. This issue is fixed in versions 4.1.11 and 4.2.6.

Title
MaxKB < 2.10.0 - Server-Side Request Forgery via downloadCallbackUrl and download_url Parameters
Summary
MaxKB before 2.10.0 contains a server-side request forgery vulnerability in tool creation and update endpoints that allows authenticated users to make arbitrary server requests by supplying unvalidated downloadCallbackUrl and download_url parameters. Attackers with default workspace USER role can exploit this to access internal network services by providing malicious URLs to the ToolSerializer endpoints.

Title
NewsBlur < 14.5.0 - Server-Side Request Forgery via add_url Endpoint
Summary
NewsBlur before version 14.5.0 contains a server-side request forgery vulnerability in the add_url endpoint that allows authenticated users to make arbitrary server requests to internal networks by failing to filter private IP addresses. Attackers can exploit this to access localhost services and cloud metadata endpoints, enabling internal network scanning and sensitive data exfiltration.

Title
Huly Platform - Server-Side Request Forgery via /import Endpoint
Summary
Huly Platform through 0.7.423, fixed in commit 68cbf8a contains an authenticated server-side request forgery vulnerability in the /import endpoint of front pod that allows workspace users to make arbitrary server requests. Attackers can exploit this by supplying malicious URLs to fetch internal services, exfiltrate responses, and replay credentials against backend systems.

Title
9Router: Kiro region injection allows authenticated SSRF with Authorization header forwarding
Summary
9Router is an AI router & token saver. Prior to 0.5.6, the Kiro API-key validation endpoint POST /api/oauth/kiro/api-key builds an upstream URL using a user-controlled region value, allowing an authenticated attacker to supply a crafted region such as kiro-canary.local:8443# and cause 9Router to send the Kiro validation request to an attacker-controlled host while forwarding the submitted Kiro API key as an Authorization header. This issue is fixed in version 0.5.6.

Title
9Router: Authenticated Server-Side Request Forgery (SSRF) via OIDC Provider Test Endpoint
Summary
9Router is an AI router & token saver. In 0.5.4 and earlier, the POST /api/auth/oidc/test endpoint in src/app/api/auth/oidc/test/route.js passes the user-controlled issuerUrl parameter to fetchOidcDiscovery() in src/lib/auth/oidc.js without restricting private or loopback destinations, allowing unauthenticated attackers when dashboard login is disabled to scan internal services and reflect OIDC discovery fields including token_endpoint and jwks_uri.

Summary
9Router is an AI router & token saver. Prior to 0.5.2, 9router validates image URLs by resolving the host before fetching, but open-sse/translator/concerns/image.js performs the later server-side image fetch with a separate DNS resolution. An authenticated attacker with access to the LLM proxy can use a vision-capable model and an attacker-controlled DNS name that first resolves to a public IP and then rebinds to an internal address, allowing server-side requests to internal-only HTTP services. This issue is fixed in version 0.5.2.

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.
