A path traversal vulnerability exists in the `install` and `uninstall` API endpoints of parisneo/lollms-webui version V12 (Strawberry). This vulnerability allows attackers to create or delete directories with arbitrary paths on the system. The issue arises due to insufficient sanitization of user-supplied input, which can be exploited to traverse directories outside the intended path.
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.
