Summary

CVE-2026-85972 is a high-severity Incorrect Implementation of Authentication Algorithm (CWE-303) vulnerability in Progress MarkLogic Server (inferred from references). Its CVSS base score is 7.4 (High).

Operationally, exploitation aligns with the MITRE ATT&CK technique External Remote Services (T1133); ranked at the 15th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog.

The strongest mitigations our analysis identified map to SA-11 (Developer Testing and Evaluation) and SA-15 (Development Process, Standards, and Tools) — see the control section below for these in your framework.

Vulnerability Data

Progress MarkLogic Server 12.x releases before 12.1.0 and 11.x releases before 11.3.7 do not sufficiently verify the identity of a Kerberos authentication service in certain password-based authentication configurations. A network-positioned attacker could impersonate trusted authentication infrastructure, potentially resulting in unauthorized…

Mitigating Controls

Mitigating Controls (NIST 800-53 r5) AI

Developer testing and evaluation at post-design stages directly uncovers incorrect implementations of required authentication algorithms.

Requiring documented development processes, standards, and tools reduces the chance that an established authentication algorithm is coded incorrectly.

Secure SDLC practices directly require correct implementation of authentication algorithms.

degrades

Cryptography control addresses proper use of authentication algorithms but is broader than authentication alone.

blocks

A.8.25 mandates security requirements, secure coding, checkpoints, testing and developer capability in the SDLC which reaches incorrect algorithm implementation for auth (via secure coding, testing and vuln prevention/fixing), but this is only a minority slice of the weakness class as most instances arise from flawed design/requirements rather than implementation errors caught in dev.

blocks

Application security requirements can specify correct authentication algorithm use but do not guarantee correct implementation.

prevents

Secure coding practices reduce the likelihood of incorrect authentication algorithm implementation.

finds

Security testing can detect flawed authentication implementations but does not prevent them by itself.
