CVE-2024-26138Network attack vector

Information disclosure via public license JSON document

Published Feb 21, 2024 · Updated Apr 22, 2025

Missing authorization in XWiki SAS Licensing Application before 1.24.2 allows remote attackers to read license and owner data. The public Licenses.Code.LicenseJSON document returns the instance ID, license details, and the owner's name and email without an access check. No account or user interaction is required; exposure is limited to confidentiality, but the data links active-install records to an instance and supports targeted phishing.
