Remote Class Loading — openjdk-orb JDKBridge honours CDR codebase URL under -secmgr (pre-auth :3528) (JBoss EAP)

Pre-auth remote class loading via IIOP: 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. findings/jboss-eap44.md
