MarkLogic Server: Improper Privilege Management
CVE-2026-7327 is a high-severity improper privilege management vulnerability in MarkLogic Server from Progress Software, with a CVSS 3.1 base score of 8.1 out of 10. It can be exploited remotely over the network by an attacker with administrator privileges, but only if a user takes part, for example by opening a link or file. The record lists versions 11.3.6, 12.0.3 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 0.39% 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 11.3.6 or 12.0.3, whichever matches your release line, or a later version.
- Read the advisory on community.progress.com for workarounds and exact fixed builds.
- Because the attack needs a user to take part, warn users about unexpected links and files related to this product until it is patched.

Official description
An improper privilege management vulnerability in the REST API document processing pipeline of Progress MarkLogic Server before 11.3.6 and 12.0.3 allows an authenticated user with an administrative REST role to escalate privileges. This can result in unauthorized disclosure of sensitive server-side data when it is accessed by a higher-privileged user.

The underlying weakness: Improper Privilege Management
The product does not properly assign, modify, track, or check privileges for an actor, creating an unintended sphere of control for that actor.
How developers prevent this class of flaw
- Very carefully manage the setting, management, and handling of privileges. Explicitly manage trust zones in the software.
- Follow the principle of least privilege when assigning access rights to entities in a software system.
- Consider following the principle of separation of privilege. Require multiple conditions to be met before permitting access to a system resource.
