A flaw was found in Apache PDFBox. A local user with writing rights to a specific directory could be exploited via a malicious PDF file when using the ExtractEmbeddedFiles example. This path traversal (CWE-22) vulnerability, which allows an attacker to access files and directories outside of the intended directory, enables arbitrary file write attempts.

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.
