Summary
Important: python3.14 security, bug fix, and enhancement update
Details
Python is an interpreted, interactive, object-oriented programming language, which includes modules, classes, exceptions, very high level dynamic data types and dynamic typing. Python supports interfaces to many system calls and libraries, as well as to various windowing systems.
Security Fix(es):
- python: cpython: Python: Arbitrary code execution via command injection in webbrowser.open() API (CVE-2026-4786)
- python: Python: Cross-Site Scripting (XSS) vulnerability in http.cookies module (CVE-2026-6019)
Bug Fix(es) and Enhancement(s):
- [10.2.z]Update python3.14 to 3.14.5 for the incremental GC changes (JIRA:AlmaLinux-176147)
For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page(s) listed in the References section.

Title
BaseCookie.js_output() does not neutralize embedded characters
Summary
http.cookies.Morsel.js_output() returns an inline <script> snippet and only escapes " for JavaScript string context. It does not neutralize the HTML parser-sensitive sequence </script> inside the generated script element. Mitigation base64-encodes the cookie value to disallow escaping using cookie value.
Severity

Exploitation: none
Automatable: no
Technical Impact: partial
