CVE-2026-85975

Progress MarkLogic Server 12.x releases before 12.1.0 and 11.x releases before 11.3.7 do not consistently validate TLS certificate hostnames for certain outbound connections. A network-positioned attacker could exploit this weakness to intercept or modify communications with an affected service.

Progress MarkLogic Server 12.x releases before 12.1.0 may use cleartext transport for certain cluster-management communications. A network-positioned attacker could intercept or modify information transmitted through an affected connection.

Progress MarkLogic Server 12.x releases before 12.1.0 and 11.x releases before 11.3.7 do not sufficiently verify the identity of a Kerberos authentication service in certain password-based authentication configurations. A network-positioned attacker could impersonate trusted authentication infrastructure, potentially resulting in unauthorized access or modification of protected data.

Progress MarkLogic Server 12.x releases before 12.1.0 and 11.x releases before 11.3.7 assign overly permissive operating-system permissions to certain log files, which could allow a local user to read or alter log data. The corrected default permissions apply to newly created and rotated logs; existing logs retain their current permissions until remediated.

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 restrict access to certain security-sensitive information. A remote authenticated attacker with limited management permissions could obtain this information, which could result in unauthorized access to protected resources.

Progress MarkLogic Server 12.x releases before 12.1.0 and 11.x releases before 11.3.7 contain memory-safety defects in the JavaScript engine integration that could result in memory corruption, controlled process failure, or server instability.

A vulnerability in Progress MarkLogic Server before versions 12.1.0 and 11.3.7 allows an authenticated Query Console user to supply unsafe path values to a privileged filesystem helper, potentially resulting in disclosure of arbitrary server files.
