mintplex-labs/anything-llm is vulnerable to a relative path traversal attack, allowing unauthorized attackers with a default role account to delete files and folders within the filesystem, including critical database files such as 'anythingllm.db'. The vulnerability stems from insufficient input validation and normalization in the handling of file and folder deletion requests. Successful exploitation results in the compromise of data integrity and availability.
The product uses external input to construct a pathname that should be within a restricted directory, but it does not properly neutralize sequences such as ".." that can resolve to a location that is outside of that directory.
