Until then, they should apply the fix provided in GitHub PR\n427.\n\nThe 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\".\n\nUsers who have copied this example into their production code should apply the mentioned change. The example\nhas been changed accordingly and is available in the project repository.","dates":{"published":"2026-04-14T08:09:39.517Z","modified":"2026-04-14T19:50:07.000Z","reserved":null,"kevAdded":[],"kevDue":[]},"cvss":{"headline":{"score":4.3,"severity":"medium","version":"3.1","versionLabel":"v3.1","source":"CVE.org","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:L/A:N","computed":false,"selection":"backend-summary"},"metrics":[{"version":"3.1","versionLabel":"v3.1","source":"CVE.org","score":4.3,"severity":"medium","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:L/A:N","exploitability":null,"impact":null,"computed":false},{"version":"3.1","versionLabel":"v3.1","source":"OSV
