"The version of Apache ActiveMQ running on the remote host is prior to 5.19.8 or 6.x prior to 6.2.7. It is, therefore,
affected by multiple vulnerabilities:

  - Improper Input Validation vulnerability in Apache ActiveMQ, Apache ActiveMQ All, Apache ActiveMQ Stomp. A remote
    unauthenticated peer that can reach an exposed STOMP connector can trigger denial-of-service behavior by sending a
    negative content-length. For the NIO STOMP transport, an attacker can keep streaming body bytes and grow the
    per-connection command buffer beyond configured limits to cause OOM. For the blocking STOMP protocol, an error will
    instead force abnormal transport exception handling for the affected connection and closure. (CVE-2026-49432)

  - Memory Allocation with Excessive Size Value vulnerability in Apache ActiveMQ Client, Apache ActiveMQ, Apache
    ActiveMQ All. An unauthenticated network attacker can cause a broker DoS by sending a crafted WireFormatInfo frame
    with a malicious large size value. The value is not validated and causes the broker to attempt allocation during
    pre-auth negotiation which can trigger OOM and crash the broker. (CVE-2026-50734)

  - 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. (CVE-2026-49877)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version
number.");
