Impact

Due to a URL parsing issue, Requests releases prior to 2.32.4 may leak .netrc credentials to third parties for specific maliciously-crafted URLs.

Workarounds

For older versions of Requests, use of the .netrc file can be disabled with trust_env=False on your Requests Session (docs).

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.

Announcements

• 📣 Requests is adding inline types. If you have a typed code base that
  uses Requests, please take a look at #​7271. Give it a try, and report
  any gaps or feedback you may have in the issue. 📣

Security

• CVE-2026-25645 requests.utils.extract_zipped_paths now extracts
  contents to a non-deterministic location to prevent malicious file
  replacement. This does not affect default usage of Requests, only
  applications calling the utility function directly.

Improvements

• Migrated to a PEP 517 build system using setuptools. (#​7012)

Bugfixes

• Fixed an issue where an empty netrc entry could cause
  malformed authentication to be applied to Requests on
  Python 3.11+. (#​7205)

Deprecations

• Dropped support for Python 3.9 following its end of support. (#​7196)

Documentation

• Various typo fixes and doc improvements.

v2.32.5

Compare Source

Bugfixes

• The SSLContext caching feature originally introduced in 2.32.0 has created
  a new class of issues in Requests that have had negative impact across a number
  of use cases. The Requests team has decided to revert this feature as long term
  maintenance of it is proving to be unsustainable in its current iteration.

Deprecations

• Added support for Python 3.14.
• Dropped support for Python 3.8 following its end of support.

v2.32.4

Compare Source

Security

• CVE-2024-47081 Fixed an issue where a maliciously crafted URL and trusted
  environment will retrieve credentials for the wrong hostname/machine from a
  netrc file.

Improvements

• Numerous documentation improvements

Deprecations

• Added support for pypy 3.11 for Linux and macOS.
• Dropped support for pypy 3.9 following its end of support.
