Prior to 1.13.0, URI.String in uri.go concatenates CertFile, KeyFile, CACertFile, and ServerName values directly into an AMQPS query string instead of encoding them as URL query parameters with url.Values. If an application accepts a TLS asset path containing ampersand or equals delimiters and later reparses the serialized URI with ParseURI, the embedded delimiters can create or overwrite connection options, including paths to TLS certificate, key, or CA files. This can corrupt connection configuration or select unintended local cryptographic assets. 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-2026-77404)\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-465g-fh3v-9jw4\n\n## Vendor advisories\n\n- **Red Hat VEX** · Important · affected: Cryostat 4, Multicluster Global Hub, OpenShift Serverless, Red Hat Advanced Cluster Management for Kubernetes 2, Red Hat OpenStack Platform 18.0, Red Hat Quay 3 · no fix planned: Cryostat 4, Multicluster Global Hub, OpenShift Serverless, Red Hat Advanced Cluster Management for Kubernetes 2, … · updated 2026-09-21 · [vex](https://security.access.redhat.com/data/csaf/v2/vex/2026/cve-2026-77404.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":48,"depthScoreParts":{"impact":47.8,"likelihood":0,"exploitation":0,"ransomware":0},"changes":[]}
