GHSA-465g-fh3v-9jw4: github.com/rabbitmq/amqp091-go (CVE-2026-77404)

Package	Ecosystem	Affected	Fixed in
github.com/rabbitmq/amqp091-go	Go	<1.13.0	1.13.0

Machine-written summary

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

GHSA-465g-fh3v-9jw4 affects the Go package github.com/rabbitmq/amqp091-go before 1.13.0. TLS file paths are appended to connection URI query strings without escaping, so paths containing & or = can inject extra parameters that overwrite settings when the URI is re-parsed. An attacker who controls part of a TLS file path that the application uses could alter connection settings or load different TLS files. Upgrade to version 1.13.0 or later.
