Changelog Security Highlights (3.6.1 → 3.7.2)

• CoreDNS dependency v1.14.2 → v1.14.4 — Several important security fixes remediated (see details below)
• Chart 3.7.2 adds RBAC permission for discovery.k8s.io/endpointslices — opt-in endpoint resolution
• Chart 3.7.1 bumps bundled app version to v1.8.0 (from v1.7.0)
• Feature additions (service label selector, Node hostname DNS resolution) — non-security

The dependency bump from CoreDNS v1.14.2 (bundled with old chart) to v1.14.4 (bundled with new chart) fixes the following verified CVEs that affect the CoreDNS server embedded in k8s-gateway:

CVE	Severity	Fixed in	Description
CVE-2026-35579	CRITICAL (9.8)	1.14.3	TSIG authentication bypass in gRPC/QUIC/DoH/DoH3 transports
CVE-2026-32934	HIGH (7.5)	1.14.3	DoQ unbounded goroutine & memory growth DoS
CVE-2026-32936	HIGH (7.5)	1.14.3	DoH GET path oversized dns= parameter DoS
CVE-2026-33190	HIGH (7.5)	1.14.3	tsig plugin bypass on non-plain-DNS transports
CVE-2026-33489	HIGH (7.5)	1.14.3	transfer plugin wrong ACL stanza selection
CVE-2026-62309	HIGH (7.5)	1.14.4	proxyproto plugin crash from 28-byte UDP datagram

Recommendations

• MERGE PRIORITY: LOW — No known CVEs found in the k8s-gateway chart or application itself. The old version (3.6.1) is clean.
• ⚠️ Important context: The old chart bundles CoreDNS v1.14.2 which exposes 5 HIGH/CRITICAL CVEs (fixed in v1.14.3). The new chart (3.7.2) bundles CoreDNS v1.14.4 which fixes all of these. While not direct k8s-gateway vulnerabilities, this is a strong practical reason to merge promptly depending on your CoreDNS transport configuration.
• Verify that your deployment does not use DoQ, DoH, DoH3, gRPC, or proxyproto with CoreDNS — if it does, the upgrade is security-critical.
• Review the feature additions in v3.7.0 (serviceLabelSelector) and v3.7.2 (endpointslice RBAC) before merging.
