XML External Entity Injection in Eclipse Foundation Jaxb Ri (core) (CVE-2026-92877)

Sources read

Source agreement

Tam uyum

Evidence confidence

%55

Short explanation

A high-severity vulnerability in the Eclipse Foundation jaxb-ri (core) component allows attackers to read local files via out-of-band XXE due to reliance solely on FEATURE_SECURE_PROCESSING for blocking XML external entity resolution (S0).

Why does it matter?

This unauthenticated vulnerability can allow attackers to access sensitive data through vulnerable systems (S0).

What should be done?

Follow official vendor advisories and apply updates (S0)

Show the technical text from the sources

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.
