Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

The requests package versions before 2.33.0 are affected by insecure temp file reuse in the extract_zipped_paths() utility function. It reuses a predictable filename in the system temp directory without validating existing files, so a local attacker with write access to that directory could plant a malicious file that gets loaded. Standard use of requests is not affected; only applications calling this function directly are. Upgrade to requests 2.33.0 or later, or, if that is not possible, set TMPDIR to a directory with restricted write access.
