amqp091-go is a Go AMQP 0.9.1 client. Before version 1.13.0, a compromised or malicious AMQP broker can force the client to allocate resources for and process content body frames that exceed the negotiated frame_max limit. This can lead to unexpected memory consumption or application-layer denial of service (DoS), bypassing the protocol's built-in framing constraints. Version 1.13.0 contains a fix. No known workarounds are available.

There are packages installed that are affected by a vulnerability referenced in the following CVE:

  - amqp091-go is a Go AMQP 0.9.1 client. Before version 1.13.0, a compromised or malicious AMQP broker can
    force the client to allocate resources for and process content body frames that exceed the negotiated
    frame_max limit. This can lead to unexpected memory consumption or application-layer denial of service
    (DoS), bypassing the protocol's built-in framing constraints. Version 1.13.0 contains a fix. No known
    workarounds are available. (CVE-2026-79921)

The version of FreeBSD installed on the remote host is prior to tested version. It is, therefore, affected by a vulnerability as referenced in the 5d69ee28-adb9-11f1-9d0e-4c526214c986 advisory.

    amqp091-go developers report:
    Before version 1.13.0, a compromised or malicious AMQP broker                 can force the client to allocate resources for and process                 content body frames that exceed the negotiated frame_max limit.
                This can lead to unexpected memory consumption or                 application-layer denial of service (DoS), bypassing the                 protocol's built-in framing constraints.
    Redpanda Connect vendored an affected amqp091-go release               up to version 4.108.0; 4.109.0 bumps it to 1.14.0.

Tenable has extracted the preceding description block directly from the FreeBSD security advisory.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.
