MarkLogic Server: Use of Hard-coded Cryptographic Key

Published Updated By the CyberSecBulletin desk

CVE-2026-85963 is a high-severity use of hard-coded cryptographic key vulnerability in MarkLogic Server from Progress Software, with a CVSS 3.1 base score of 7.5 out of 10. It can be exploited remotely over the network by an unauthenticated attacker, 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 0.43% chance of exploitation within 30 days, which is low compared with other CVEs.

Next patch cycle

High severity with no evidence of exploitation so far.

What to do

  1. Update MarkLogic Server to 11.3.7 or 12.1.0, whichever matches your release line, or a later version.
  2. Until you can update, restrict network access to the affected service so it is not reachable from untrusted networks.

Official description

Progress MarkLogic Server 12.x releases before 12.1.0 and 11.x releases before 11.3.7 include deprecated OpsDirector functionality with weaknesses that could allow an unauthenticated remote attacker to make unauthorized requests to internal services or forge trusted requests, potentially resulting in unauthorized access to protected information.
