UID2-7456: Suppress CVE-2026-56131 / CVE-2026-56407 / CVE-2026-56408 (libexpat) in .trivyignore
Trivy flagged three HIGH-severity CVEs in the Alpine system library libexpat (installed
2.8.1-r0) shipped in theeclipse-temurin:21-jre-alpine-3.23base image:doPrologcopyStringDecision
Suppress in
.trivyignorewith a 1-month expiry (exp:2026-08-09).Rationale
Not exploitable in our context — libexpat is a native C XML parser; this service parses XML via the JVM's built-in JAXP/Xerces implementation (pure Java), with no JNI bindings or native dependencies that call into libexpat, so the crafted-XML attack path is not reachable. All three CVEs are fixed in Alpine v3.23
libexpat >= 2.8.2-r0; the suppression will be revisited when the pinnedeclipse-temurinbase image is rebuilt with the fixed package (at which point the entry can be removed).Jira: https://thetradedesk.atlassian.net/browse/UID2-7456
