Critical MarkLogic Vulnerabilities Enable Persistent Admin Takeover
Progress Software disclosed 31 security vulnerabilities in MarkLogic Server on October 12, 2026, with five rated critical. Two of the most severe flaws (CVE-2026-85947 and CVE-2026-85948) allow accounts with limited management privileges to escalate to persistent administrator control of the database server. CVE-2026-85947 enables forest-management accounts to create persistent admin accounts, while CVE-2026-85948 exploits an XQuery injection flaw in deprecated Management API paths. The vulnerabilities affect MarkLogic 11.x before 11.3.7 and 12.x before 12.1.0, with fixes available since September 10, 2026. The disclosure follows another batch of 10 critical flaws published in August 2026, indicating an ongoing pattern of privilege escalation vulnerabilities in enterprise database platforms that require immediate attention from organizations relying on MarkLogic for mission-critical data management.
