Amazon Linux 2 : python-pip, --advisory ALAS2-2026-3256 (ALAS-2026-3256)

low Nessus Plugin ID 311223

Synopsis

The remote Amazon Linux 2 host is missing a security update.

Description

It is, therefore, affected by a vulnerability as referenced in the ALAS2-2026-3256 advisory.

When pip is installing and extracting a maliciously crafted wheel archive, files may be extracted outside the installation directory. The path traversal is limited to prefixes of the installation directory, thus isn't able to inject or overwrite executable files in typical situations. (CVE-2026-1703)

Tenable has extracted the preceding description block directly from the tested product security advisory.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Run 'yum update python-pip' or or 'yum update --advisory ALAS2-2026-3256' to update your system.
