CVE-2026-49877: CWE-285 Improper Authorization in Apache Software Foundation Apache ActiveMQ
Improper Authorization vulnerability in Apache ActiveMQ. An authenticated low-privilege Web Console user by default can access /admin/* paths in the Web Console. The default Jetty settings incorrectly did not limit those paths to only admins. This issue affects Apache ActiveMQ: before 5.19.8, from 6.0.0 before 6.2.7. Users are recommended to upgrade to version 6.2.7 or 5.19.8, which fixes the issue.

This affects Apache ActiveMQ versions prior to 5.19.8 and versions from 6.0.0 up to but not including 6.2.7. The vulnerability has a CVSS 3.1 score of 8.1, indicating high severity with network attack vector, low attack complexity, requiring low privileges but no user interaction, and impacts confidentiality and integrity. No known exploits in the wild have been reported. The vendor recommends upgrading to fixed versions 5.19.8 or 6.2.7.
Potential Impact
An authenticated user with low privileges can access administrative paths (/admin/*) in the ActiveMQ Web Console, potentially leading to unauthorized disclosure and modification of sensitive information or configuration. The vulnerability does not affect availability. The CVSS score of 8.1 reflects high impact on confidentiality and integrity.
Mitigation Recommendations
Upgrade Apache ActiveMQ to version 5.19.8 or 6.2.7 or later, where this improper authorization issue is fixed. There is no indication of temporary workarounds or vendor-managed cloud service remediation. Patch status is confirmed by the vendor advisory recommending these versions.
