CVE-2026-52760Network attack vector

Stored XSS via unescaped JMS message ID

Published Jun 30, 2026 · Updated Jun 30, 2026

Stored XSS in Apache ActiveMQ and Web Console before 5.19.8 and 6.0.0 through 6.2.6 allows remote authenticated users to run script. The queue browse page inserts a producer-controlled JMS message ID into rendered HTML without neutralizing HTML or JavaScript syntax. An authenticated producer must submit the crafted ID and an administrator must browse the queue, causing the payload to execute in the administrator's browser.
