Amazon Linux 2 Security Advisory: ALAS2-2026-3358
Advisory Released Date: 2026-06-22
Advisory Updated Date: 2026-06-22
A flaw was found in pip, the package installer for Python. A remote attacker can exploit this vulnerability by tricking a victim into installing a malicious Python wheel. This wheel contains specially crafted entry-point names that use directory traversal or absolute paths. This allows pip to write generated script wrappers outside the intended installation directory, leading to arbitrary file overwrite. This can severely impact system integrity and availability, and in certain scenarios, may lead to arbitrary code execution. (CVE-2026-8643)
