Last updated on: 2026-10-12

Assigner: Progress Software Corporation

Description
Progress MarkLogic Server 12.x releases before 12.1.0 and 11.x releases before 11.3.7 do not sufficiently isolate user-supplied code executed through certain REST and XDBC evaluation paths from HTTP request, response, and session state. An attacker able to execute code through an affected path could perform unauthorized actions or compromise an authenticated session.

Executive Summary

This vulnerability affects Progress MarkLogic Server versions before 12.1.0 and 11.3.7. It allows user-supplied code executed through certain REST and XDBC paths to interact with HTTP request, response, and session state. This could let an attacker perform unauthorized actions or take over an authenticated session.

Impact Analysis

If exploited, this flaw could allow attackers to execute unauthorized actions on the server or hijack authenticated sessions. This may lead to data breaches, unauthorized access to sensitive information, or system compromise depending on the server's role and data stored.

Compliance Impact

This vulnerability could lead to unauthorized access or data breaches, violating confidentiality requirements in GDPR and HIPAA. Organizations using affected MarkLogic versions may face compliance violations, legal penalties, and reputational damage if exploited.

Mitigation Strategies

Upgrade Progress MarkLogic Server to version 12.1.0 or later for 12.x releases, or to version 11.3.7 or later for 11.x releases. This addresses the insufficient isolation of user-supplied code in REST and XDBC evaluation paths.
