CVE-2026-85959 Progress Software Corporation CVE debrief

Who should care

Defenders and security teams responsible for Progress MarkLogic Server 11.x and 12.x releases should assess exposure and prioritize verifying authentication logging. This includes reviewing current logging configurations, implementing compensating controls, and monitoring for unauthorized access or credential misuse. Security teams should also track exceptions, retest remediated assets, and close the item only after evidence is documented.

Why it matters

Defenders should prioritize verifying authentication logging in Progress MarkLogic Server 11.x and 12.x releases, assessing exposure, and implementing compensating controls due to insufficient authentication logging.

• Verify authentication logging configuration and compensating controls
• Assess exposure of Progress MarkLogic Server 11.x and 12.x releases
• Monitor for unauthorized access or credential misuse

Technical summary

Progress MarkLogic Server 12.x releases before 12.1.0 and 11.x releases before 11.3.7 do not consistently record successful authentication events in audit logs. This could limit customers' ability to detect and investigate unauthorized access or credential misuse. The vulnerability affects authentication logging, not data integrity or confidentiality. Defenders should focus on verifying authentication logging and implementing compensating controls to mitigate potential exposure. Successful exploitation could allow attackers to evade detection.

Defensive priority

Defenders should prioritize verifying authentication logging in Progress MarkLogic Server 11.x and 12.x releases, assessing exposure, and implementing compensating controls.

Recommended defensive actions

• Verify authentication logging in Progress MarkLogic Server 11.x and 12.x releases
• Assess exposure and implement compensating controls
• Monitor for unauthorized access or credential misuse
• Review vendor advisory for security alert bulletin
• Check relevant monitoring, detection, and logs for exposed assets that need extra review
• Track exceptions, retest remediated assets, and close the item only after evidence is documented.
• Confirm whether affected product deployments exist in managed environments and assign an owner for follow-up.

Evidence notes

The CVE record and source item indicate that Progress MarkLogic Server 12.x releases before 12.1.0 and 11.x releases before 11.3.7 do not consistently record successful authentication events in audit logs.
