📋 Recommended Actions ⚠️ Action Required Immediate patching is highly recommended to address multiple security vulnerabilities. Review RBAC changes for ACME Challenge and Order resources, especially if you have custom automation that directly manipulates these internal objects. 📝 Summary Cert-manager v1.20.3 delivers essential security updates and crucial internal refinements. This patch release addresses three vulnerabilities across core Go dependencies, including a high-severity HTTP/2 rapid reset variant in golang.org/x/net (CVE-2024-24783), and medium-severity fixes for golang.org/x/crypto (CVE-2024-24784) and github.com/moby/spdystream (CVE-2024-24785).
