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.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:L/A:N","score":4.3},"cwes":["CWE-22"],"references":["https://github.com/apache/pdfbox/pull/427/changes","https://lists.apache.org/thread/j8l07tgzy9dm8d8n0f3c45h7zg7t3ld6","https://lists.apache.org/thread/op3lyx1ngzy4qycn06l6hljyf28ff0zs"],"products":["apache:pdfbox"],"source":"nvd","synced_at":"2026-10-26T22:26:44.656832877+00:00"},"epss":{"cve":"CVE-2026-33929","score":0.00711,"percentile":0.53278,"date":"2026-10-26"},"kev":null,"osv":[{"id":"GHSA-gcj8-76p4-g2fq","url":"https://osv.dev/vulnerability/GHSA-gcj8-76p4-g2fq","summary":"Apache PDFBox Examples: Path Traversal in PDFBox ExtractEmbeddedFiles Example Code","modified":"2026-04-15T00:16:14.897124Z","packages":[{"ecosystem":"Maven","name":"org.apache.pdfbox:pdfbox-examples","purl":"pkg:maven/org.apache.pdfbox/pdfbox-examples","ranges":[">=2.0.24 <2.0.37"],"fixed":["2.0.37"]},{"ecosystem":"Maven","name":"org.apache.pdfbox:pdfbox-examples","purl":"pkg:maven/org.apache.pdfbox/pdfbox-examples","ranges":[">=3.0.0 <3.0.8"],"fixed":["3.0.8"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
