…at 2.8.1-r0) Bumps the base image across the public, Azure CC and GCP OIDC operator Dockerfiles. The 2026-06-22 rebuild of 21-jre-alpine-3.23 (sha256:3f08b138) ships libexpat 2.8.1-r0, which fixes CVE-2026-45186 in the Azure CC and GCP OIDC private-operator images (the previous fix only patched ./Dockerfile, so those two builds were still failing). Also retires the now-redundant explicit libexpat upgrade from ./Dockerfile. NOTE: this changes the Azure CC and GCP OIDC enclave measurements — a private- operator release + enclave re-registration is required for the new digest.

What
Bumps the
eclipse-temurinbase image tosha256:3f08b138…(the 2026-06-22 rebuild of21-jre-alpine-3.23) across the public, Azure CC, and GCP OIDC operator Dockerfiles, and removes the now-redundant explicitlibexpatupgrade from./Dockerfile.Why
The previous CVE-2026-45186 fix only patched
./Dockerfile(Public + AWS EIF). The Azure CC (scripts/azure-cc/Dockerfile) and GCP OIDC (scripts/gcp-oidc/Dockerfile) private-operator images build from their own Dockerfiles and were still shipping the vulnerable libexpat 2.7.5-r0, so the "Publish All Operators" Azure/GCP build jobs kept failing.The new base image ships libexpat 2.8.1-r0, fixing CVE-2026-45186 across all three Alpine images at the base layer (verified by pulling the digest). The explicit
apk add --upgrade libexpatis no longer needed and is removed.
