Unauthorized data access via Kerberos service impersonation
Published Oct 12, 2026 · Updated Oct 12, 2026
Kerberos authentication bypass in Progress MarkLogic Server allows attackers to read or modify protected data via service impersonation. The supplied source record describes insufficient authentication-service identity verification in certain password-based configurations; public research did not corroborate the implementation details. Exploitation requires a network position enabling impersonation of trusted authentication infrastructure, rather than ordinary access to a database endpoint.

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.
- Affected versionversion=11.0.0 <11.3.7
- Affected versionversion=12.0.0 <12.1.0
