Name of the Vulnerable Software and Affected Versions LemonLDAP::NG versions 2.18.x through 2.19.1

Description The issue is related to incorrect credential validation, allowing attackers to bypass OAuth2 client authentication.

There is no information provided about the estimated number of potentially affected devices worldwide or details about real-world incidents where this issue was exploited.

Recommendations For LemonLDAP::NG versions 2.18.x through 2.19.1, update to version 2.19.2 or later to resolve the issue.
