  "title": "Fallback tar extraction in pip doesn\u0027t check symbolic links point to extraction directory",
  "description": "When extracting a tar archive pip may not check symbolic links point into the extraction directory if the tarfile module doesn\u0027t implement PEP 706. Note that upgrading pip to a \u0022fixed\u0022 version for this vulnerability doesn\u0027t fix all known vulnerabilities that are remediated by using a Python version that implements PEP 706.  Note that this is a vulnerability in pip\u0027s fallback implementation of tar extraction for Python versions that don\u0027t implement PEP 706 and therefore are not secure to all vulnerabilities in the Python \u0027tarfile\u0027 module. If you\u0027re using a Python version that implements PEP 706 then pip doesn\u0027t use the \u0022vulnerable\u0022 fallback code.  Mitigations include upgrading to a version of pip that includes the fix, upgrading to a Python version that implements PEP 706 (Python \u003E=3.9.17, \u003E=3.10.12, \u003E=3.11.4, or \u003E=3.12), applying the linked patch, or inspecting source distributions (sdists) before installation as is already a best-practice.",
