LibreChat: Incomplete Fix for CVE-2025-7105 — /api/convos/duplicate Lacks Rate Limiting Applied to /api/convos/fork

LibreChat is an enhanced ChatGPT clone that supports multiple AI providers. Prior to 0.8.4-rc1, the fix for CVE-2025-7105 added forkIpLimiter and forkUserLimiter rate limiters to POST /api/convos/fork to prevent rapid-fire conversation duplication. However, the POST /api/convos/duplicate endpoint — which is in the same file and performs the exact same expensive database operations — was not given any rate limiter. An authenticated user can bypass the CVE-2025-7105 fix by using /duplicate instead of /fork to exhaust server resources. This vulnerability is fixed in 0.8.4-rc1.
