Description

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 via file.createFile with a traversal name, then trigger document parsing to overwrite application files like startServer.js for code execution or denial of service.
