Security advisories

Bugs resolved

  • CiviCampaign: Fix error when reserving respondents for a survey (#19811)

  • Upgrader: Fix handling of "group_title" in certain upgrade-paths (dev/translation#58: #19740)

  • D8 / Asset Builder: Fail gracefully when certain resources cannot be generted (dev/core#2137: #18830)

    A common misconfiguration on Drupal 8+ is to omit enable-patching. This currently manifests as an error about crm-menubar.css. The change does not fix the misconfiguration, but it makes the error more manageable.


Special support from Deutsche Gesellschaft für Internationale Zusammenarbeit GmbH contributed significantly to this release and other contemporaneous security improvements.
