Official 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.

Technical Analysis

CVE-2026-25645 requires local access, meaning attackers must already have a foothold on the target system.

Exploitation requires low privileges, which limits the exposure to scenarios where an attacker has already gained initial access.

A successful exploit results in full integrity compromise (data manipulation), with a CVSS base score of 5.5.
