Description

Requests is a HTTP library. Prior to version 2.33.0, the `requests.utils.extract_zipped_paths()` utility function uses a predictable filename when extracting files from zip archives into the system temporary directory. If the target file already exists, it is reused without validation. A local attacker with write access to the temp directory could pre-create a malicious file that would be loaded in place of the legitimate one. Standard usage of the Requests library is not affected by this vulnerability. Only applications that call `extract_zipped_paths()` directly are impacted. Starting in version 2.33.0, the library extracts files to a non-deterministic location. If developers are unable to upgrade, they can set `TMPDIR` in their environment to a directory with restricted write access.

Notes

mdeslaur

On focal and earlier, the python-pip package bundles requests binaries when built. After updating requests, a no-change rebuild of python-pip is required. On jammy and later, requests is bundled in the python-pip package and needs to be patched. the extract_zipped_paths() function is only used to extract CA bundles provided in zip format. Nothing in the archive uses extract_zipped_paths() directly. Marking this issue as being low priority.
