📋 Recommended Actions ⚠️ Action Required Immediate upgrade is recommended to address a high-severity DNS-01 solver stability issue (GHSA-gx3x-vq4p-mhhv) and ensure robust certificate issuance validation. 📝 Summary Cert-manager v1.18.5 delivers critical updates. It fixes a high-severity DNS-01 solver panic (GHSA-gx3x-vq4p-mhhv), preventing service disruptions. It also adds robust validation for issued certificates, ensuring public keys match CSRs, and improves HTTP-01 IPv6 handling. Upgrade now for enhanced stability and security! 🔒 High-Severity Fix: ACME DNS-01 Solver Panic (GHSA-gx3x-vq4p-mhhv) A critical vulnerability identified as GHSA-gx3x-vq4p-mhhv has been addressed in this release, preventing potential denial-of-service scenarios for the ACME DNS-01 solver. Previously, the solver would incorrectly assume that DNS SOA records would always be the first entry in a DNS query response. If a DNS provider returned the SOA record at a different position, cert-manager’s DNS-01 solver could panic and crash, making it unable to process new challenges and disrupting certificate issuance. ...

📋 Recommended Actions ⚠️ Action Required Immediate upgrade is strongly recommended to address multiple high-severity security vulnerabilities. Review updates to the vendored ACME client, particularly the deprecation of TLS-SNI-01 and TLS-SNI-02 challenge types, which may impact custom ACME integrations. 📝 Summary cert-manager v1.18.4 lands with vital security fixes and significant ACME protocol updates. This release addresses multiple high-severity CVEs in the underlying Go toolchain and various golang.org/x dependencies, demanding your prompt attention to safeguard your Kubernetes clusters. Beyond security, we’ve refined ACME challenge handling, notably deprecating the insecure TLS-SNI-01 and TLS-SNI-02 challenge types. On the bright side, TLS-ALPN-01 now gracefully supports IP address identifiers, expanding its utility for diverse network configurations. Core components also see a Go version bump and updated distroless base images, boosting overall stability. Upgrade now to secure your certificate management and benefit from improved ACME capabilities. ...

Review the updates to leverage enhanced certificate handling and improve your troubleshooting experience. 📝 Summary cert-manager(v1.18.3) boosts reliability and user experience. It now supports significantly larger certificates and chains, crucial for complex deployments with many SANs. A critical fix prevents unnecessary certificate re-issuance stemming from IssuerRef defaulting. Plus, clearer error messages for malformed PEM data greatly simplify troubleshooting. Upgrade for a more stable and robust certificate management experience. ...

📋 Recommended Actions ✅ No Immediate Action Required No immediate action required. Review updates for improved ACME challenge stability and awareness of updated Ingress-Nginx testing within cert-manager’s ecosystem. This cert-manager v1.17.3 patch release focuses on enhancing the reliability of certificate issuance and ensuring robust compatibility with other crucial Kubernetes ecosystem components. You’ll find a significant increase in the ACME challenge authorization timeout, which should lead to more successful certificate requests, particularly in environments with network latency or slower DNS propagation. Additionally, our end-to-end testing environment has been updated to use a newer ingress-nginx version with its admission webhook enabled, reinforcing cert-manager’s compatibility with modern ingress configurations. ...

📋 Recommended Actions ⚠️ Action Required Review your Gateway API configurations, particularly AllowedRoutes.namespaces.from settings, as None is no longer supported and will cause validation errors. For pluginca users, ensure your cacerts bundle is complete to avoid istiod startup failures due to new, stricter validation. Upgrading is recommended for improved stability and security hardening. 📝 Summary Istio 1.26.1 lands with crucial updates, primarily focusing on robust Gateway API integration and enhanced security. This release promotes Gateway API to v1.3.0, alongside a critical fix that resolves istiod panics when processing complex Gateway API hostnames. Notably, a breaking change from upstream Gateway API means AllowedRoutes.namespaces.from: None is no longer valid, requiring configuration updates. ...

📋 Recommended Actions ⚠️ Action Required Immediate patching is highly recommended to address several security vulnerabilities in core dependencies and ensure the continued stability of your cert-manager deployments. This cert-manager v1.17.2 release delivers vital security updates by patching multiple Go dependencies that address various CVEs. Beyond these critical fixes, we’ve also refreshed our Go toolchain and base images, ensuring a more robust and secure foundation for your certificate management needs. ...

📋 Recommended Actions ⚠️ Action Required Immediate upgrade recommended for all users relying on Cloudflare DNS01 challenges to restore functionality and ensure uninterrupted certificate issuance. This cert-manager v1.17.1 patch release delivers a crucial fix for users leveraging Cloudflare DNS01 challenges. Due to a recent breaking API change from Cloudflare, cert-manager v1.17.0 and earlier versions were experiencing issues with certificate issuance via this method. This update ensures seamless operation for your ACME certificates, alongside a standard bump to the Go toolchain to v1.23.6. ...

📋 Recommended Actions ⚠️ Action Required Immediate action is not universally required but highly recommended to review the default changes for promoted feature gates (like NameConstraints and UseDomainQualifiedFinalizer now defaulting to true) and the deprecation of ValidateCAA (now defaulting to false). Adjust your configurations as necessary to maintain desired behavior, especially if you rely on the previous implicit defaults. Consider leveraging the new literal keystore password option for simplified management. ...
