  • Improved Fleet-wide Solr security hardening. We have patched a potential security issue affecting older Apache Solr versions and strengthened server-side request controls across our entire Solr infrastructure. The update was rolled out to every server automatically — no customer action is required, and your indexes and data are unaffected.

  • Improved 3-round security audit on the Drupal module: XSS protection on AI streaming output (DOMParser sanitizer), Solr injection prevention on range filters and facet values, CSRF on all admin write endpoints, and safe URL generation in CLI/cron context. 35+ issues found and fixed across all module files.
