The JAXB factory methods historically relied solely on 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.

No affected version ranges are stored yet. Use the vendor advisory before you decide this record does not apply.
