Official description
A vulnerability in danny-avila/librechat version git 81f2936 allows for path traversal due to improper sanitization of file paths by the multer middleware. This can lead to arbitrary file write and potentially remote code execution. The issue is fixed in version 0.7.6.

The underlying weakness: Path Traversal: '..filename'
The product uses external input to construct a pathname that should be within a restricted directory, but it does not properly neutralize '..filename' (leading backslash dot dot) sequences that can resolve to a location that is outside of that directory.
How developers prevent this class of flaw
- Inputs should be decoded and canonicalized to the application's current internal representation before being validated (CWE-180). Make sure that the application does not decode the same input twice (CWE-174). Such errors could be used to bypass allowlist validation schemes by introducing dangerous inputs after they have been checked.
