Title
n8n - Credential Exfiltration via Allowed HTTP Request Domains Bypass in Dynamic Node Parameters Endpoint
Summary
n8n before 2.20.0 contains a credential exfiltration vulnerability in the POST /rest/dynamic-node-parameters/options endpoint that allows authenticated users to bypass Allowed HTTP Request Domains restrictions. Attackers with credential access can cause the n8n server to issue HTTP requests with credentials to unauthorized hosts, exfiltrating sensitive authentication data.

Title
AVideo - Server-Side Request Forgery in Live/test.php via statsURL Parameter
Summary
AVideo through version 27.0 contains a server-side request forgery vulnerability in plugin/Live/test.php that allows authenticated administrators to read arbitrary URLs via the statsURL parameter, which lacks isSSRFSafeURL() validation and accepts requests to private IP ranges and cloud metadata endpoints. Attackers can exploit this by crafting requests to internal services, cloud metadata endpoints like 169.254.169.254, and localhost to retrieve sensitive information including IAM credentials, internal service responses, and network configuration details.

Nitter - Server-Side Request Forgery in /video Media Proxy Endpoint
Summary
Nitter's /video media proxy endpoint fails to validate target URLs against Twitter/X domains and uses a hardcoded default HMAC key, allowing unauthenticated attackers to compute valid HMACs for arbitrary URLs. Attackers can retrieve HTTP responses from any host reachable by the server, including cloud metadata services and internal network resources.

Title
Flowise - Server-Side Request Forgery via Execute Flow Base URL
Summary
Flowise before 3.1.0 contains a server-side request forgery vulnerability in the Execute Flow node that allows attackers to bypass security validation by providing intranet addresses through the base URL field. Attackers can initiate HTTP requests to internal network addresses, access cloud metadata, and enumerate internal services by exploiting the missing secureFetch verification in httpSecurity.ts.

Title
Crawl4AI - Server-Side Request Forgery via Direct Crawl Endpoints
Summary
Crawl4AI before 0.8.7 contains a server-side request forgery vulnerability in the /crawl, /crawl/stream, /md, and /llm endpoints that fetch arbitrary user-supplied URLs without validation. Unauthenticated attackers can bypass the internal-address blocklist using IPv6-mapped IPv4 addresses to reach internal services and cloud metadata endpoints.

Title
Crawl4AI - Server-Side Request Forgery via Webhook URLs
Summary
Crawl4AI before 0.8.7 contains a server-side request forgery (SSRF) vulnerability in the Docker API server's /crawl/job and /llm/job endpoints, which accept webhook URLs without destination validation. An attacker can supply webhook URLs pointing to private or internal IP ranges, Docker networks, or cloud metadata endpoints (e.g. 169.254.169.254), causing the server to make requests to internal services and potentially expose cloud metadata.

Title
Apache Camel Iggy: The inbound consumer maps externally-supplied Iggy message user-headers into the Exchange without a HeaderFilterStrategy, allowing injection of Camel control headers - enabling control over internal behaviour
Summary
Improper Input Validation, Exposure of Sensitive Information to an Unauthorized Actor, Server-Side Request Forgery (SSRF) vulnerability in Apache Camel in Iggy component.
The camel-iggy consumer mapped the user-headers of inbound Iggy messages into the Camel Exchange header map without applying any HeaderFilterStrategy (IggyFetchRecords copied the message user-headers straight into the Exchange). Because nothing blocked the Camel header namespace, an actor able to publish to the consumed Iggy stream/topic could set Camel-internal control headers - including CamelHttpUri (Exchange.HTTP_URI) - simply by supplying them as message user-headers. In a route where the Iggy consumer feeds a downstream HTTP producer, the injected CamelHttpUri redirects the server-side HTTP request to an attacker-chosen destination (server-side request forgery - for example to an internal service or a cloud metadata endpoint). In addition, the HTTP producer resolves Camel property placeholders on the resulting (attacker-controlled) URI, so placeholders embedded in the injected value - such as an environment-variable reference, an application property, or a vault reference - are resolved to their real values and sent to the attacker, disclosing environment variables, application properties and vault secrets.
This issue affects Apache Camel: from 4.17.0 before 4.18.3, from 4.19.0 before 4.21.0.
Users are recommended to upgrade to version 4.21.0, which fixes the issue. If users are on the 4.18.x releases stream, then they are suggested to upgrade to 4.18.3. The fix adds a dedicated IggyHeaderFilterStrategy (and a headerFilterStrategy endpoint option) that filters the Camel header namespace case-insensitively on inbound mapping, so externally-supplied Camel* / camel* headers are no longer copied into the Exchange. For deployments that cannot upgrade immediately, strip the Camel control headers from the inbound message before they reach any downstream producer (for example removeHeaders('Camel*') and removeHeaders('camel*') at the start of the route), restrict who can publish to the consumed Iggy stream/topic, and avoid bridging an untrusted consumer directly into an HTTP producer whose target URI can be driven from message headers.

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.
