CRITICALCVE-2023-26512 is a critical-severity (CVSS 9.8) Deserialization of Untrusted Data vulnerability in org.apache.eventmesh:eventmesh-connector-rabbitmq. The records list no fixed version yet; check the vendor advisory below and apply the mitigations in the meantime.
rabbitmq-connector plugin module in Apache EventMesh platforms allows attackers to send controlled message
Exploitation Status
No confirmed exploitation observed yet
- CISA assesses this as automatable — exploitation doesn’t require manual, per-target effort, which raises the odds of mass scanning and opportunistic attacks.
- A successful exploit gives an attacker total control of the affected component, not partial access.
- CISA’s own triage has not observed active exploitation or public proof-of-concept code for this CVE as of its last assessment.

Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for org.apache.eventmesh:eventmesh-connector-rabbitmq, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.
Remediation status
The records we use list no patched version of org.apache.eventmesh:eventmesh-connector-rabbitmq for CVE-2023-26512. Check the maintainer's advisory, and where your build allows, override or pin the dependency away from the vulnerable range.
Mitigate without a patch
Do not deserialise data from untrusted sources: where the format allows it, restrict deserialisation to an explicit allowlist of expected types, and prefer a data-only format (JSON, Protobuf) over one that can reconstruct arbitrary objects until you can upgrade.
