Descripción técnica

pip would incorrectly handle doubly-encoded package URLs from indexes allowing for files to be installed to arbitrary locations on disk even when installing wheels. This vulnerability requires downloading or installing a package from a malicious package index to succeed, malicious packages alone are not able to exploit this vulnerability. Note that this vulnerability only materially impacts users running `pip download` with the `--only-binary` option as installing source distributions from an untrusted index is already an unsafe operation that executes code during install time.

——14Usagi-org ai-goofish-monitor contains an unauthenticated arbitrary file read vulnerability in the GET /api/prompts/{filename} endpoint on Windows deployments that allows unauthenticated remote attackers to read arbitrary files by supplying absolute Windows paths or backslash-based traversal sequences. Attackers can bypass the incomplete path traversal guard, which only blocks forward slashes and '..', by providing absolute paths such as Windows system file locations, causing os.path.join to discard the intended prompts directory prefix and expose files accessible to the application process.9d
