CVE-2026-92877

JAXB Factory XXE Vulnerability Allowing Local File Read

Published Oct 12, 2026 CVSS 4.0 · 8.3 High EPSS < 1% KEV · Not listed
Description
The JAXB factory methods historically relied solely on `FEATURE_SECURE_PROCESSING` to prevent XML External Entity (XXE) resolution. On JAXP implementations where that feature alone does not block external entity resolution, an attacker who can get untrusted XML unmarshalled through JAXB can read local files via out-of-band XXE.
