MarkLogic Server: Exposure of Sensitive Information to an Unauthorized Actor
CVE-2026-85966 is a high-severity exposure of sensitive information to an unauthorized actor vulnerability in MarkLogic Server from Progress Software, with a CVSS 3.1 base score of 7.7 out of 10. It can be exploited remotely over the network by an attacker with a low-privileged account, without any action from a user. The record lists versions 11.3.7, 12.1.0 as the first without the flaw, so updating MarkLogic Server to one of those releases or later removes the exposure. There is no confirmed exploitation so far. EPSS estimates a 0.3% chance of exploitation within 30 days, which is low compared with other CVEs.
High severity with no evidence of exploitation so far.
What to do
- Update MarkLogic Server to 11.3.7 or 12.1.0, whichever matches your release line, or a later version.

Official description
Progress MarkLogic Server 12.x releases before 12.1.0 and 11.x releases before 11.3.7 do not sufficiently restrict access to certain security-sensitive information. A remote authenticated attacker with limited management permissions could obtain this information, which could result in unauthorized access to protected resources.

The underlying weakness: Exposure of Sensitive Information to an Unauthorized Actor
The product exposes sensitive information to an actor that is not explicitly authorized to have access to that information.
How developers prevent this class of flaw
- Compartmentalize the system to have safe areas where trust boundaries can be unambiguously drawn. Do not allow sensitive data to go outside of the trust boundary and always be careful when interfacing with a compartment outside of the safe area. Ensure that appropriate compartmentalization is built into the system design, and the compartmentalization allows for and reinforces privilege separation functionality. Architects and designers should rely on the principle of least privilege to decide the appropriate time to use privileges and the time to drop privileges.
