Summary
Requests has Insecure Temp File Reuse in its extract_zipped_paths() utility function
Details
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.
Severity ?
4.4 (Medium)
