Description
LoLLMs WEBUI provides the Web user interface for Lord of Large Language and Multi modal Systems. A critical Server-Side Request Forgery (SSRF) vulnerability has been identified in all known existing versions of `lollms-webui`. The `@router.post("/api/proxy")` endpoint allows unauthenticated attackers to force the server into making arbitrary GET requests. This can be exploited to access internal services, scan local networks, or exfiltrate sensitive cloud metadata (e.g., AWS/GCP IAM tokens). As of time of publication, no known patched versions are available.
