Jul 1, 2025July 2025 monthly summary for grails-core: Focused security hardening on the Grails Updater by implementing XXE mitigation in the XML parser. The patch disables external entity expansion and enforces secure SAX processing to prevent XML External Entity (XXE) attacks in the update pipeline. This work aligns with secure-by-default XML handling and follows the CodeQL guidance (issue #14936). The change was implemented in grails/grails-core with commit 8dc40cd5dfd1a05f172c3860cc724b0d0bb89272 and requires minimal risk to the existing update flow.
