Authenticated privilege escalation via LDAP query injection
Published Dec 17, 2025 · Updated Dec 17, 2025
LDAP injection in Homarr before 1.45.3 allows remote authenticated users to gain privileges and access other users’ groups. The LDAP authentication flow inserts crafted account input into a user-and-group search without rejecting LDAP filter characters, then accepts a query that matches multiple users. An instance must use LDAP authentication, and the attacker must already have a user account; successful exploitation crosses group boundaries.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
