Python · Pip · CVE-2013-1629
**Name of the Vulnerable Software and Affected Versions**
pip versions prior to 1.3
**Description**
The issue allows man-in-the-middle attackers to execute arbitrary code via a crafted response to a "pip install" operation, as pip retrieves packages from the PyPI repository using HTTP and does not perform integrity checks on package contents.
**Recommendations**
For pip versions prior to 1.3, consider updating to version 1.3 or later to resolve the issue. As a temporary workaround, restrict the use of pip to trusted networks to minimize the risk of man-in-the-middle attacks.
