SCA: security update for pypdf (GHSA-42gh-23hr-vphw)

high Tenable Self-Hosted Container Security Plugin ID 478052

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - pypdf is a free and open-source pure-python PDF library. Prior to 6.21.3, pypdf can take excessive time to
 retrieve page labels from a crafted PDF containing a flat page-label number tree with many ranges. The
 page_labels property resolves each page independently and repeatedly scans the same /Nums array from the
 beginning, causing work to grow with both the page count and the number of label ranges. This issue is
 fixed in version 6.21.3. (CVE-2026-119206)

Solution

Update the pypdf library and its related packages to version 6.21.3 or later.
