Name of the Vulnerable Software and Affected Versions
Drupal External Authentication versions 0.0.0 through 2.0.13
Description
Improper handling of case sensitivity allows privilege escalation. The module fails to ensure exact matching of externally supplied identity values when storing and looking up authentication mappings under specific database collation configurations. This issue primarily affects sites using certain MySQL or MariaDB collation settings for the authentication mapping storage.
Recommendations
Update Drupal External Authentication to a version newer than 2.0.13.
