An early warning has been issued regarding a vulnerability in the amqp091-go client library that could lead to memory exhaustion or denial of service. Users of versions prior to 1.13.0 are potentially affected.

What happened

A vulnerability has been reported in the amqp091-go client library where a compromised or malicious AMQP broker can force the client to process oversized content body frames. This can result in unexpected memory consumption or application-layer denial of service (DoS), effectively bypassing the protocol's framing constraints. The vulnerability is under investigation and has not been exploited in the wild as of the latest reports.

The affected component is the amqp091-go library for Go, specifically versions prior to 1.13.0. This vulnerability allows a malicious broker to send frames larger than the negotiated frame_max limit, leading to potential memory exhaustion on the client side.
