Summary
LibreChat, klon ChatGPT z dodatkowymi funkcjami, w wersjach od 0.8.2-rc2 do 0.8.2 jest podatny na atak typu server-side request forgery (SSRF) podczas korzystania z akcji agenta lub MCP. Poprzednia podatność SSRF została naprawiona, jednak wprowadzone poprawki nie weryfikują, czy rozwiązywanie DNS prowadzi do prywatnego adresu IP.
Risk Assessment
Atakujący może obejść zabezpieczenia i uzyskać dostęp do wewnętrznych zasobów, takich jak wewnętrzne API RAG lub punkty końcowe metadanych instancji chmurowych, co stwarza poważne zagrożenie dla bezpieczeństwa organizacji.
Recommendation
Zaleca się aktualizację do wersji 0.8.3-rc1, która zawiera poprawkę eliminującą tę podatność.

Original NVD description (English source)
LibreChat is a ChatGPT clone with additional features. Versions 0.8.2-rc2 through 0.8.2 are vulnerable to a server-side request forgery (SSRF) attack when using agent actions or MCP. Although a previous SSRF vulnerability (https://github.com/danny-avila/LibreChat/security/advisories/GHSA-rgjq-4q58-m3q8) was reported and patched, the fix only introduced hostname validation. It does not verify whether DNS resolution results in a private IP address. As a result, an attacker can still bypass the protection and gain access to internal resources, such as an internal RAG API or cloud instance metadata endpoints. Version 0.8.3-rc1 contains a patch.
