Title

Openjdk-orb: incomplete fix for cve-2026-15560,unauthed class loading via iiop in eap

Summary

when EAP runs with -secmgr, the openjdk-orb's JDKBridge honours attacker-supplied CDR codebase URLs during object unmarshalling on :3528, allowing an unauthenticated attacker to load and instantiate arbitrary classes from a remote URL in the server JVM before EJB security interceptors run.

If removing the iiop-openjdk subsystem from the JBoss EAP configuration (standalone.xml or domain.xml), a full server restart is required, causing temporary service downtime.\n\nCaveats: Blocking port 3528 or disabling the IIOP subsystem will prevent legitimate remote clients from communicating over IIOP/CORBA."
