## What is CVE-2026-67615?

CVE-2026-67615 is a high-severity unsafe deserialization vulnerability in Apereo Foundation openEQUELLA, published on 22 Sep 2026. Any signed-in user can exploit it over the network, with no action from the victim.

### Official description

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.

Weakness: CWE-502 (Deserialization of Untrusted Data), CWE-184 (Incomplete List of Disallowed Inputs)

Check this codebase for CVE-2026-67615 and fix it if it is affected.

What it is: CVE-2026-67615 is a high-severity unsafe deserialization vulnerability in Apereo Foundation openEQUELLA, published on 22 Sep 2026. Any signed-in user can exploit it over the network, with no action from the victim.
Exploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2026-67615 exists.

Affected product: Apereo Foundation openEQUELLA. No package-level version data is available, so check the vendor advisory linked from the reference page.

Task:
1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.
2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.
3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.
4. Run the tests and summarise what changed and why.
5. If nothing in the project is affected, say so and change nothing.
