Detailsinfo

A vulnerability was found in Apache ActiveMQ Client, ActiveMQ Broker and ActiveMQ (unknown version). It has been classified as critical. This affects an unknown code block. The manipulation with an unknown input leads to a path traversal vulnerability. CWE is classifying the issue as CWE-22. The product uses external input to construct a pathname that is intended to identify a file or directory that is located underneath a restricted parent directory, but the product does not properly neutralize special elements within the pathname that can cause the pathname to resolve to a location that is outside of the restricted directory. This is going to have an impact on confidentiality, integrity, and availability.

The advisory is shared at lists.apache.org. This vulnerability is uniquely identified as CVE-2026-33227. The exploitability is told to be easy. It is possible to initiate the attack remotely. Neither technical details nor an exploit are publicly available. The price for an exploit might be around USD $0-$5k at the moment (estimation calculated on 04/10/2026). MITRE ATT&CK project uses the attack technique T1006 for this issue.

The vulnerability scanner Nessus provides a plugin with the ID 305954 (Apache ActiveMQ < 5.19.3 / 5.19.4, 6.x < 6.2.2 / 6.2.3 Classpath Path Traversal), which helps to determine the existence of the flaw in a target environment.

Upgrading eliminates this vulnerability.

The vulnerability is also documented in the databases at Tenable (305954) and EUVD (EUVD-2026-19586). If you want to get the best quality for vulnerability data then you always have to consider VulDB.
