What is CVE-2025-4573?

An LDAP group ID injection vulnerability exists in certain versions of Mattermost due to improper validation of LDAP group ID attributes. This flaw allows an authenticated administrator with specific permissions to exploit the vulnerability via the API endpoint by executing LDAP search filter injection when the objectGUID is set as the Group ID Attribute.
