NVD Description

Note: Versions mentioned in the description apply only to the upstream python-3.14 package and not the python-3.14 package as distributed by Minimos. See How to fix? for Minimos:latest relevant fixed versions and status.

The fix for CVE-2026-0672, which rejected control characters in http.cookies.Morsel, was incomplete. The Morsel.update(), |= operator, and unpickling paths were not patched, allowing control characters to bypass input validation. Additionally, BaseCookie.js_output() lacked the output validation applied to BaseCookie.output().
