Summary

The Eclipse Foundation jaxb-ri (core) package, at versions 4.0.4 and 4.0.9, relies only on FEATURE_SECURE_PROCESSING to block XML external entity resolution in its JAXB factory methods. On JAXP implementations where that feature alone does not block external entities, the flaw is an improper restriction of XML external entity references (CWE-611). An attacker who can get untrusted XML unmarshalled through JAXB can read local files with out-of-band XXE.

Description from the CNA

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.
