LibreChat disclosed on 2026-03-16 a log-injection vulnerability (CVE-2026-4276) in its RAG API v0.7.0 caused by unsanitized file_id input enabling CRLF injection to forge log entries. An authenticated attacker can tamper audit trails and potentially trigger downstream XSS or remote command execution when logs are processed by insecure tools. No vendor patch is available; mitigations include input sanitization, disabling unused pgvector, and validating outputs.
