CVE-2026-25645

A flaw was found in the `requests` HTTP library, specifically in the `requests.utils.extract_zipped_paths()` function, which is used to load Certificate Authority (CA) bundles. A local attacker can exploit this vulnerability by pre-creating a malicious CA bundle file in the system's temporary directory. When a vulnerable application initializes the `requests` library, it may load this malicious file instead of the legitimate CA bundle, leading to a bypass of security controls and potential integrity compromise.

CVE-2026-25645 (GCVE-0-2026-25645)

Vulnerability from cvelistv5 – Published: 2026-03-25 17:02 – Updated: 2026-03-25 22:48

Title

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

Summary

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.

Severity

4.4 (Medium)
