RabbitMQ End of Life: Which Versions Are EOL and What Are Your Options?

Which RabbitMQ Versions Are End of Life?

As of mid-2026, every RabbitMQ 3.x version is at or past community end-of-life:

• RabbitMQ 3.8.x — EOL (community support ended)
• RabbitMQ 3.9.x — EOL
• RabbitMQ 3.10.x — EOL
• RabbitMQ 3.11.x — EOL (community support ended November 2023)
• RabbitMQ 3.12.x — EOL (community support ended July 2024)
• RabbitMQ 3.13.x — EOL (community support ended December 2024)
• RabbitMQ 4.0.x — Current community-supported release

This means the RabbitMQ core team does not backport security fixes, bug fixes, or CVE remediations to versions 3.8 through 3.13. When a vulnerability is discovered and patched in RabbitMQ 4.x, the fix is not made available for 3.x.

What Does This Mean Practically?

Consider CVE-2026-41823, an AMQP 1.0 frame parsing vulnerability affecting RabbitMQ 3.11–3.13 with a CVSS score of 9.1. The upstream fix was committed to RabbitMQ 4.0. For teams running 3.11, 3.12, or 3.13, there is no official patch. The vulnerability was disclosed publicly. The CVE ID, affected versions, and exploitation details are publicly available.

Any attacker who reads the security announcement — which is public — knows that unpatched RabbitMQ 3.x deployments are vulnerable. This is precisely the exposure profile that PCI DSS Requirement 6.3.3 and SOC 2 CC7 are designed to address.

Why Are So Many Enterprises Still Running RabbitMQ 3.x?

The RabbitMQ 3.x to 4.x migration is non-trivial for production environments. Key changes in RabbitMQ 4.0 include:

• Classic mirrored queues are no longer supported; all queues must be quorum or stream queues
• Changes to consumer acknowledgment behavior under certain edge conditions
• Minimum Erlang/OTP version requirement increase to 26.x
• Updated management API paths for some endpoints

For an enterprise running hundreds of vhosts, dozens of custom exchanges and queue topologies, and applications built against the 3.x behavior contract, this migration takes time to test and execute safely. Scheduling "migrate RabbitMQ" into a Q3 roadmap is easier said than done when the platform handles order processing, payment events, or clinical messaging.

What About Broadcom Tanzu RabbitMQ?

Many enterprises are in the additional bind of having commercial Broadcom Tanzu RabbitMQ support either expiring or priced beyond what the value justifies. Broadcom's 2023 acquisition of VMware restructured the Tanzu portfolio around a per-core licensing model with a 72-core minimum — a threshold most enterprises hit quickly, generating annual invoices in the $200,000–$1,000,000 range for what is functionally the same codebase as community RabbitMQ.

Teams leaving Tanzu need somewhere to go for CVE coverage and compliance documentation during the migration period. That's precisely what extended lifecycle support addresses.

Your Options for EOL RabbitMQ

Migrate to RabbitMQ 4.x

The permanent solution. OSSeva recommends planning RabbitMQ 4.x migration for all customers — the question is timeline. A well-planned migration typically takes 3–6 months for straightforward deployments and 6–12 months for complex multi-vhost, multi-application environments. The migration requires: queue topology audit, quorum queue migration planning, client library updates, integration testing, and a staged production rollout.

Extended lifecycle support while migrating

OSSeva delivers backported CVE patches for RabbitMQ 3.11, 3.12, and 3.13. Patches are delivered as signed Docker images, Helm chart updates, and direct binary tarballs. Each release includes a CVE attestation letter for compliance documentation. This keeps your security posture active and your auditors satisfied while you execute the 4.x migration at a controlled pace.

Exit Broadcom Tanzu to OSSeva-supported OSS RabbitMQ

For teams paying Tanzu pricing, OSSeva provides a migration toolkit that exports your existing vhost, exchange, queue, binding, and policy definitions and redeploys them on an OSSeva-supported OSS RabbitMQ cluster. Cost reduction is typically 60–80% compared to Tanzu pricing.

Erlang/OTP Compatibility

RabbitMQ 3.11–3.13 support Erlang/OTP 25.x and 26.x. OSSeva patches also cover the Erlang runtime itself for CVEs affecting the Erlang version bundled with or required by supported RabbitMQ builds. Erlang/OTP CVEs are less frequent but can affect RabbitMQ's TLS implementation, the BEAM scheduler, and the distribution protocol.

Compliance Considerations

For enterprises in financial services, healthcare, or government, the compliance exposure from unpatched EOL RabbitMQ is direct. PCI DSS v4.0 Requirement 6.3.3 requires all system components to be protected against known vulnerabilities. Running RabbitMQ 3.x with disclosed, unpatched CVEs is a direct finding under this requirement. OSSeva's extended support provides the patch delivery and attestation documentation QSAs and internal audit teams require.
