Public exploitNot knownno public code found

Progress MarkLogic Server 12.x releases before 12.1.0 and 11.x releases before 11.3.7 allow a remote attacker with query-execution access to invoke an XQuery evaluation function without the additional required evaluation privilege, which could result in server-side code execution with elevated permissions.

CVSS

Base score: 9.9
Version: 3.1
Vector: CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H

Exploitation probability (EPSS)

Probability of exploitation in the next 30 days: 0.45 %
Percentile among all scored CVEs: 38
Score date: 10/20/2026

EPSS (Exploit Prediction Scoring System, FIRST) estimates how likely a vulnerability is to be exploited in the wild within 30 days. It complements CVSS (impact) and CISA KEV (confirmed exploitation).
