Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

The amqp091-go Go library, versions before 1.13.0, does not enforce the negotiated frame_max limit on content body frames. A malicious or compromised AMQP broker can send an oversized body frame after connection setup, causing the client to allocate large amounts of memory, which can lead to out-of-memory crashes. Upgrade to version 1.13.0 or later.

Written 1 Nov 2026.
