CVE-2026-111822: Apache ActiveMQ, Apache ActiveMQ Runtime Config: ActiveMQ retains write access after live ACL revocation

HighCVSS 8.1 · v3.1—No exploit Fix available

Noroxi assessment

Priority: Monitor (action score 32/100)

The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
Probability of exploitation in the next 30 days: 0.36% (FIRST EPSS).
Anyone who can reach it over the internet can trigger it. A low-privileged account is enough. No user action is required. No special conditions are required; it is repeatable.
Fixed version: Apache Software Foundation Apache ActiveMQ 5.19.12, 6.3.3; Apache Software Foundation Apache ActiveMQ Runtime Config 5.19.12, 6.3.3.

Low priority for now. Upgrade to Apache Software Foundation Apache ActiveMQ 5.19.12, 6.3.3; Apache Software Foundation Apache ActiveMQ Runtime Config 5.19.12, 6.3.3 or later.

Primary sources: NVD · CVE.org · FIRST EPSS

Improper invalidation of cached authorizations vulnerability in Apache ActiveMQ, Apache ActiveMQ Runtime Config. After the runtime configuration plugin removes a principal's write grant on a destination, an authenticated connection opened before the change can keep sending to that destination, including through a new anonymous producer, while fresh connections and new explicit producers are denied. This issue affects Apache ActiveMQ: from 6.0.0 before 6.3.3, before 5.19.12; Apache ActiveMQ Runtime Config: from 6.0.0 before 6.3.3, before 5.19.12. Users are recommended to upgrade to version 6.4.0, 6.3.3 or 5.19.12, which fixes the issue.
