SCA: security update for org.apache.pdfbox:pdfbox-examples (GHSA-gcj8-76p4-g2fq)

medium Tenable Self-Hosted Container Security Plugin ID 440425

Description

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

 - Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') vulnerability in Apache
 PDFBox Examples. This issue affects the ExtractEmbeddedFiles example in Apache PDFBox: from 2.0.24 through
 2.0.36, from 3.0.0 through 3.0.7. Users are recommended to update to version 2.0.37 or 3.0.8 once
 available. Until then, they should apply the fix provided in GitHub PR 427. The ExtractEmbeddedFiles
 example contained a path traversal vulnerability (CWE-22) mentioned in CVE-2026-23907. However the change
 in the releases 2.0.36 and 3.0.7 is flawed because it doesn't consider the file path separator. Because of
 that, a user having writing rights on /home/ABC could be victim to a malicious PDF resulting in a write
 attempt to any path starting with /home/ABC, e.g. "/home/ABCDEF". Users who have copied this example into
 their production code should apply the mentioned change. The example has been changed accordingly and is
 available in the project repository. (CVE-2026-33929)

Solution

Update the org.apache.pdfbox:pdfbox-examples library and its related packages to version 2.0.37 or later.
