CVE-2026-84725
HighCVSS 8.1Exploitation Probability (EPSS)
Low risk28th percentile - higher than 28% of all known CVEs
Summary
When EAP runs with -secmgr, openjdk-orb's JDKBridge honors attacker-supplied CDR codebase URLs during object unmarshalling on port 3528, allowing an unauthenticated attacker to load and instantiate arbitrary classes from a remote URL in the server JVM before EJB security interceptors run.
Risk Assessment
An attacker could remotely execute malicious code in the application server context, bypassing EJB security mechanisms, potentially leading to full system compromise.
Recommendation
Restrict access to port 3528 or disable the -secmgr option if not required, and monitor incoming traffic for suspicious codebase URLs.
