…at 2.8.1-r0) The 2026-06-22 rebuild of 21-jre-alpine-3.23 (sha256:3f08b138) now ships libexpat 2.8.1-r0, so the explicit 'apk add --upgrade libexpat' added in the previous fix (CVE-2026-45186) is no longer needed and is removed, matching the repo convention of dropping per-package upgrades once the base carries the fix.

What
Bumps the
eclipse-temurinbase image from the prior pin tosha256:3f08b138…(the 2026-06-22 rebuild of21-jre-alpine-3.23) and removes the explicitapk add --upgrade libexpatadded in the previous fix.Why
The new base image ships libexpat 2.8.1-r0, which resolves CVE-2026-45186 (HIGH) at the base layer. The explicit per-package upgrade is therefore redundant and is dropped — matching this repo's convention of removing
--upgradelines once the base image carries the fix (cf. the earlier gnutls cleanup).Verified by pulling the new digest:
libexpat-2.8.1-r0is installed.
