CVE-2026-67615
CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N
Summary
openEQUELLA before 2026.1.0 contains an authenticated remote code execution vulnerability that allows any authenticated non-guest user to execute arbitrary code by exploiting Java deserialization in the HTTP invoker endpoint at /invoker/*. 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.
Affected Software
| Vendor | Product | Version Range | Status |
|---|---|---|---|
| Apereo Foundation | openEQUELLA | 0 < 2026.1.0 | affected |
Weaknesses
- CWE-502: Deserialization of Untrusted Data
- CWE-184: Incomplete List of Disallowed Inputs
Workarounds
Deployments that can't upgrade immediately should firewall or VPN the /invoker/* endpoints and restrict them to only those who genuinely need access.
