HighCVSS 8.8
Published: Translated: NVD NIST

Summary

LobeHub Chat from 1.84.26 before 2.1.49 contains a path traversal vulnerability that allows authenticated users to write arbitrary files by supplying unsanitized file names to writeTempFile(). Attackers can create a file record with a traversal name and then trigger document parsing to overwrite application files such as startServer.js for code execution or denial of service.

Risk Assessment

An authenticated attacker could overwrite application files, leading to code execution or service disruption.

Recommendation

Upgrade LobeHub Chat to version 2.1.49 or later and enforce validation and sanitization of file names passed to writeTempFile().
