GHSA-4pcv-mg8v-vrgf: PraisonAI: Server-Side Request Forgery (SSRF) in SearxNG / search_web tools via attacker-controlled searxng_url parameter

A Server-Side Request Forgery (SSRF) vulnerability in the SearxNG / search_web search tools allows an attacker to make the server perform requests to arbitrary internal endpoints and read the responses back. The searxng_url argument is passed directly to requests.get() with no validation of scheme, host, or port. Because searxng_url is exposed to the LLM as a tool parameter and search_web / searxng_search are part of the default agent toolset, the vulnerability is reachable through prompt injection in any content an agent ingests (web pages, files, tool output). This enables reading internal services and APIs, internal host/port enumeration, and in cloud environments reachability of the instance metadata endpoint (169.254.169.254) with potential IAM/credential exposure.
