DRUPAL-CONTRIB-2026-098
The advisory, in context
This module enables you to authenticate Drupal users against external identity providers.
The module does not sufficiently ensure exact matching of externally supplied identity values when storing and looking up authentication mappings under certain database collation configurations.
This vulnerability is minimally mitigated by the fact that it affects only sites using impacted MySQL or MariaDB collation settings for the module’s authentication mapping storage. Affected collations are quite common so all sites are encouraged to upgrade.
