Technical Analysis
CVE-2026-85957 is an XML External Entity (XXE) vulnerability in Progress Software Corporation's MarkLogic Server 11.x releases prior to 11.3.7. The issue arises because the SAML parser configuration permits processing of external Document Type Definitions (DTDs) or entities. This improper restriction can be exploited to cause unintended network access or disclose sensitive information. The vulnerability is identified as CWE-611 and has a CVSS 3.1 base score of 7.5, indicating high severity. The affected versions are >=11.0.0 and <11.3.7. No vendor advisory or patch links are provided in the input data.
Potential Impact
Successful exploitation of this vulnerability could allow an attacker to cause unintended network interactions or disclose sensitive information through the processing of external XML entities in the SAML parser. The CVSS vector indicates the attack can be performed remotely without privileges or user interaction and impacts confidentiality but not integrity or availability.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, consider restricting or disabling processing of external entities in XML parsers if configurable. Monitor vendor communications for updates on patches or official mitigations.
