In version 3.22.0 of aimhubio/aim, the LocalFileManager._cleanup function in the aim tracking server accepts a user-specified glob-pattern for deleting files. The function does not verify that the matched files are within the directory managed by LocalFileManager, allowing a maliciously crafted glob-pattern to lead to arbitrary file deletion.
The product uses external input to construct a pathname that is intended to identify a file or directory that is located underneath a restricted parent directory, but the product does not properly neutralize special elements within the pathname that can cause the pathname to resolve to a location that is outside of the restricted directory.
