Update org.apache.rocketmq:rocketmq-broker to version 5.1.1 or later. Run your dependency manager's update command and verify no transitive dependencies pin the vulnerable version. Use O3 Security's SCA scanner to confirm the fix is applied across your entire dependency tree.

Is GHSA-x3cq-8f32-5f63 actively exploited in the wild?

Yes. There are 20 known exploit references for GHSA-x3cq-8f32-5f63, including 14 in-the-wild exploitations observed on GitHub and other sources. Treat this as actively exploitable and prioritize patching immediately. All exploit code should only be run in an isolated sandbox environment for research or authorized testing — never against production systems without explicit written authorization.

What is the EPSS score for GHSA-x3cq-8f32-5f63?

GHSA-x3cq-8f32-5f63 has an EPSS (Exploit Prediction Scoring System) score of 94.4%, placing it in the 100th percentile of all CVEs. EPSS is maintained by FIRST.org and estimates the probability that a vulnerability will be exploited in the wild within the next 30 days. A score above 50% indicates significantly elevated exploitation risk — immediate patching is strongly recommended.

Is GHSA-x3cq-8f32-5f63 in the CISA Known Exploited Vulnerabilities catalog?

Yes. GHSA-x3cq-8f32-5f63 (Apache RocketMQ Command Execution Vulnerability) was added to CISA's Known Exploited Vulnerabilities (KEV) catalog on 2023-09-06. CISA required all US federal civilian agencies to remediate this vulnerability by 2023-09-27. The required action was: Apply mitigations per vendor instructions or discontinue use of the product if mitigations are unavailable. Being listed in the KEV catalog is the strongest possible confirmation of active exploitation — treat this as a critical priority.

What type of vulnerability is GHSA-x3cq-8f32-5f63?

GHSA-x3cq-8f32-5f63 is classified as Code Injection (CWE-94). This weakness type describe the underlying flaw category, which helps determine the potential impact and the right class of mitigation. This is a high-impact weakness class that often enables remote code execution or data exposure.

When was GHSA-x3cq-8f32-5f63 published, and has it been updated?

GHSA-x3cq-8f32-5f63 was published on July 6, 2023 and was last updated on October 22, 2025. Advisory data evolves as severity scores, affected ranges, and exploit intelligence are revised — always check the latest version of the advisory before acting.

Real-time download stats are indexed for npm and PyPI packages. This vulnerability affects Maven packages — download data is not available via public APIs for these ecosystems.

Description

For RocketMQ versions 5.1.0 and below, under certain conditions, there is a risk of remote command execution.

Several components of RocketMQ, including NameServer, Broker, and Controller, are leaked on the extranet and lack permission verification, an attacker can exploit this vulnerability by using the update configuration function to execute commands as the system users that RocketMQ is running as. Additionally, an attacker can achieve the same effect by forging the RocketMQ protocol content.

To prevent these attacks, users are recommended to upgrade to version 5.1.1 or above for using RocketMQ 5.x or 4.9.6 or above for using RocketMQ 4.x .
