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) 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.

Red Hat has issued a security advisory for python3 in Red Hat Enterprise Linux 8.4 variants addressing two vulnerabilities: CVE-2026-6100, a use-after-free in decompression modules that could lead to arbitrary code execution or information disclosure, and CVE-2026-4786, a command injection vulnerability in the webbrowser.open() API allowing arbitrary code execution. These vulnerabilities affect python3 packages in Red Hat Enterprise Linux 8.4 Advanced Update Support and Extended Update Support. The advisory rates the security impact as Important and provides updated packages to remediate these issues.

Two security vulnerabilities affecting Python 3.9 on Red Hat Enterprise Linux 9.6 Extended Update Support have been identified and addressed. The first (CVE-2026-6100) involves a use-after-free flaw in decompression modules that could lead to arbitrary code execution or information disclosure. The second (CVE-2026-4786) involves command injection via the webbrowser.open() API, also allowing arbitrary code execution. Red Hat has released updated python3.9 packages to remediate these issues. The update is rated as Important by Red Hat Product Security. No CVSS scores are provided in the advisory.
