Prior to 1.13.0, PlainAuth values defined in auth.go retain passwords as exported plaintext fields in Connection.Config.SASL after a successful PLAIN authentication handshake. The Connection.openComplete method in connection.go does not clear those values. Code with access to the Connection object, including reflective loggers, application performance monitoring agents, debugging utilities, and panic handlers, can traverse the configuration and expose the credentials to logs or state captures. The credential remains available for the lifetime of the connection instead of being cleared after authentication. This issue is fixed in version 1.13.0.\n\n## Remediation\n\nRefer to the linked advisories for vendor-supplied fixes and affected version ranges.\n\n## Package advisory (CVE-2026-77407)\n\nAffected packages:\n\n- `github.com/rabbitmq/amqp091-go < 1.13.0`\n\nPatched in:\n\n- `github.com/rabbitmq/amqp091-go 1.13.0`\n\nSource: https://github.com/advisories/GHSA-27gv-rfvv-22mv\n\n## Vendor advisories\n\n- **Red Hat VEX** · Moderate · affected: Cryostat 4, Custom Metric Autoscaler operator for Red Hat Openshift, Multicluster Global Hub, OpenShift Serverless, Red Hat Advanced Cluster Management for Kubernetes 2, Red Hat OpenStack Platform 18.0, … · no fix planned: Red Hat Advanced Cluster Management for Kubernetes 2, Red Hat Quay 3, Cryostat 4, Custom Metric Autoscaler operator for Red Hat Openshift, … · updated 2026-09-21 · [vex](https://security.access.redhat.com/data/csaf/v2/vex/2026/cve-2026-77407.json)\n- **RHSA-2026:68290** · Red Hat · fixed in: Red Hat Hardened Images · released 2026-09-16 · [advisory](https://access.redhat.com/errata/RHSA-2026:68290)","depth":"twilight","depthScore":39,"depthScoreParts":{"impact":38.5,"likelihood":0,"exploitation":0,"ransomware":0},"changes":[]}
