python-pip: Path traversal via malicious entry point name in pip wheel installation allows arbitrary file overwrite

CVE-2026-8643 [HIGH] CWE-22 python-pip: Path traversal via malicious entry point name in pip wheel installation allows arbitrary file overwrite
python-pip: Path traversal via malicious entry point name in pip wheel installation allows arbitrary file overwrite
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.
Statement: This Important flaw in pip's wheel installation process allows for arbitrary file overwrite due to path traversal. An attacker could exploi
