How to Fix CVE-2026-25645

To remediate this vulnerability, upgrade all affected Requests dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

requests fixed: 2.33.0 
pip install requests>=2.33.0
Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release: 

pip show requests

How to Check if You Are Affected

To determine whether your Python environment is affected by CVE-2026-25645, inspect your installed packages using pip:

pip show requests

Analyze the terminal output to locate any version of Requests in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 2.33.0), your application is affected.

Note: The pip show requests command checks currently installed packages in your active Python environment.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-377: Insecure Temporary File, where creating and using insecure temporary files can leave application and system data vulnerable to attack. In Requests, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

### 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.
