Attackers can bypass the class-name denylist enforced by PluginAwareObjectInputStream by nesting a serialized payload inside a java.security.SignedObject, causing the inner stream to be deserialized by a separate ObjectInputStream that does not apply the denylist, ultimately reaching a JNDI sink and enabling code execution.","cvssScore":8.8,"cvssSeverity":"HIGH","cvssVector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","cwes":["CWE-184","CWE-502"],"vendors":[],"products":[],"references":[{"url":"https://blog.evan.lat/posts/openeq","tags":[]},{"url":"https://github.com/openequella/openEQUELLA/releases/tag/2026.1.0","tags":[]},{"url":"https://www.vulncheck.com/advisories/openequella-authenticated-rce-via-java-deserialization-in-http-invoker","tags":[]}],"exploitRefs":[{"url":"https://github.com/openequella/openEQUELLA/releases/tag/2026.1.0","tags":[]}],"hasPoc":true,"ai":{"summary":"This vulnerability allows authenticated non-guest users to execute arbitrary code by exploiting Java deserialization in the HTTP invoker endpoint, leading to remote code execution.","exploitability":"Exploitation requires an authenticated non-guest user and knowledge of the specific Java deserialization payload.
