• CVE-2024-23321: 0.89% estimated exploitation activity in the next 30 days; percentile 59.41 (FIRST EPSS, 2026-11-03). This is a model estimate, not proof of exploitation or customer exposure.

As published by the source; long descriptions are shortened.

For RocketMQ versions 5.2.0 and below, under certain conditions, there is a risk of exposure of sensitive Information to an unauthorized actor even if RocketMQ is enabled with authentication and authorization functions. An attacker, possessing regular user privileges or listed in the IP whitelist, could potentially acquire the administrator's account and password through specific interfaces. Such an action would grant them full control over RocketMQ, provided they have access to the broker IP address list. To mitigate these security threats, it is strongly advised that users upgrade to version 5.3.0 or newer. Additionally, we recommend users to use RocketMQ ACL 2.0 instead of the original RocketMQ ACL when upgrading to version Apache RocketMQ 5.3.0.

# Patch Next advisory brief: CVE-2024-23321

Advisory: Apache RocketMQ Vulnerable to Unauthorized Exposure of Sensitive Data
IDs: CVE-2024-23321, GHSA-q9w2-h4cw-8ghp
Record: https://patchnext.com/advisories/cve-2024-23321 (revision 1, source checked 26 Oct 2026, 16:31 UTC)
Inventory: none attached. This brief comes from a public page and does not say whether any deployment is affected.
Severity: Medium (CVSS 6.0)
Exploitation: no confirmed exploitation recorded. Patch Next confirms exploitation only from CISA KEV.
Vendor response: Vendor fix available; fixed versions by package: org.apache.rocketmq:rocketmq-all 5.3.0. A vendor fix does not mean a deployment is fixed.

## Affected components
- Maven org.apache.rocketmq:rocketmq-all: affected >= 4.5.2, < 5.3.0; fixed in 5.3.0

## Suggested inspection (read-only)
- Maven org.apache.rocketmq:rocketmq-all: check the installed version with your package manager.

## Supported action
Upgrade each affected component to a fixed version on its release line. For a transitive dependency, upgrade the parent package or add an override or constraint, then regenerate the lockfile. Redeploy every environment that ran an affected version.

## Required regression checks
- Run the test suite and a production build.
- Exercise the features that depend on org.apache.rocketmq:rocketmq-all.
- Repeat the inspection and confirm that only fixed versions remain installed.

## Rollback considerations
- Keep the previous lockfile and deployment artifact. Rolling back reinstates the vulnerable version, so apply any documented mitigation while you fix forward.

## Unresolved questions
- Which deployments run an affected version?
- Exploitation status can change. Check again before lowering the priority.
- Mark the work resolved only after the fixed version is verified in production.

## Sources
- Verified: https://github.com/advisories/GHSA-q9w2-h4cw-8ghp (GitHub-reviewed advisory GHSA-q9w2-h4cw-8ghp lists affected ranges: Maven org.apache.rocketmq:rocketmq-all >=4.5.2 <5.3.0)
