CVE-2026-25645: Requests has Insecure Temp File Reuse in its extract_zipped_paths() utility function

Noroxi assessment

Priority: Monitor (action score 22/100)

  • Public proof-of-concept code exists (GitHub); there is no record of exploitation in the wild.
  • Probability of exploitation in the next 30 days: 0.18% (FIRST EPSS).
  • Someone with local access to the system can trigger it. A low-privileged account is enough. No user action is required. No special conditions are required; it is repeatable.
  • Fixed version: azl3 python-requests 2.31.0-3 on Azure Linux 3.0 2.31.0-4; azl3 python-requests 2.31.0-4 on Azure Linux 3.0 2.31.0-4; cbl2 python-requests 2.27.1-8 on CBL Mariner 2.0 2.27.1-9.

Low priority for now. Upgrade to azl3 python-requests 2.31.0-3 on Azure Linux 3.0 2.31.0-4; azl3 python-requests 2.31.0-4 on Azure Linux 3.0 2.31.0-4; cbl2 python-requests 2.27.1-8 on CBL Mariner 2.0 2.27.1-9 or later.

Primary sources: NVD · CVE.org · FIRST EPSS

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.
