Requests has Insecure Temp File Reuse in its extract_zipped_paths() utility function

view advisory published 2026-03-25Licence: CC-BY-4.0

### Impact 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. ### Affected usages **Standard usage of the Requests library is not affected by this vulnerability.** Only applications that call `extract_zipped_paths()` directly are impacted. ### Remediation Upgrade to at least Requests 2.33.0, where the library now 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.
