CVE-2026-85963

Progress MarkLogic Server 12.x releases before 12.1.0 and 11.x releases before 11.3.7 may use cleartext transport for Amazon S3 connections by default. A network-positioned attacker could intercept data or credentials transmitted through an affected connection.

Progress MarkLogic Server 12.x releases before 12.1.0 and 11.x releases before 11.3.7 enable XML external entity processing by default in multiple server paths, which could allow crafted XML to cause server-side requests or disclosure of local files.

Progress MarkLogic Server 12.x releases before 12.1.0 and 11.x releases before 11.3.7 contain an out-of-bounds write vulnerability in certain language-processing functionality. A remote authenticated attacker could exploit this vulnerability to cause server instability or limited modification of data.

Progress MarkLogic Server 12.x releases before 12.1.0 contain an out-of-bounds read vulnerability in certain query-processing functionality. A remote authenticated attacker could exploit this vulnerability to cause server instability or disclose limited information from process memory.

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.

Progress MarkLogic Server 12.x releases before 12.1.0 and 11.x releases before 11.3.7 allow a remote attacker with delegated database-administrator privileges to perform backup or restore operations on forests outside the authorized database scope, which could result in unauthorized access to or modification of security-critical data.

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.

Progress MarkLogic Server 12.x releases before 12.1.0 and 11.x releases before 11.3.7 contain an XQuery injection flaw in a deprecated Management API package path. A remote attacker with manage-user-level privileges could exploit this flaw to obtain persistent unauthorized administrative control.

Progress MarkLogic Server versions 12.x before 12.1.0 and 11.x before 11.3.7 contain an authorization flaw in certain forest-management operations. A remote attacker with forest-management privileges could exploit this flaw to create a persistent unauthorized administrator account, potentially resulting in complete unauthorized administrative control of the server.

A cross-site scripting vulnerability in the Query Console of Progress MarkLogic Server before 11.3.6 and 12.0.3 allows a remote attacker who lures an authenticated administrator to a crafted URL to execute arbitrary JavaScript in the administrator's browser session, capture credentials, and perform privileged actions on the administrator's behalf.
