Emissary-ingress, the CNCF Kubernetes API gateway built on Envoy (Mapping, Host and Listener CRDs, auth, rate limiting, canaries). Envoy 1.37 from Wolfi, the Python control plane (diagd) and the Go busyambassador built from source; upstream layout and uid 8888. Pairs with emissary-apiext.

Held: this version will not be updated in the next scheduled release. Its CVEs are listed here but not counted in the catalog totals.
Reason, as last measured
emissary (Emissary-ingress API gateway): from-source via melange, the Go busyambassador plus the Python control plane (diagd) from the tag tarball, on Wolfi Envoy 1.37 (upstream 4.1.0 ships stock Envoy 1.37.2; Wolfi envoy-1.37 is the same line). Newest line only for now: 3.x needs Emissary's own Envoy fork. STATUS 2026-11-01: BLOCKED (BLOCKED=0 -> 1), upstream-gated on the Wolfi envoy apk. The image ships Wolfi's envoy-1.37 (1.37.1-r3), which carries CVE-2026-111497 (CRITICAL, bundled brotli decoder) and on 1.38 CVE-2026-111943 (HIGH). Wolfi's secdb names 1.37.8-r0 / 1.38.6-r0 / 1.38.9-r1 as the fixes, but the public APKINDEX (read 2026-11-01) still tops out at 1.37.1-r3 and 1.38.1-r0 (memory: Wolfi fix revisions are not always public). The Go floors (x/net 0.62.0, go-jose 4.1.6) are already in the recipe and ship with the next build. Unblock when the APKINDEX carries an envoy revision at or past those fixes: move the pin, gate, dispatch.
