Prior to version 15.115.0, an access control bypass in the REST API allows a user to read data from Linked DocTypes that they are not authorized to access. When a document references another document through a Link field, the framework does not consistently enforce the linked DocType's own permissions when the record is retrieved through the REST API, so a low-privileged authenticated user can obtain fields from linked records outside their permitted scope. This issue is fixed in version 15.115.0.","published":"2026-08-26T20:17:56.920","modified":"2026-08-26T20:17:56.920","cvss":null,"epss":null,"cisaKev":null,"exploitsKnown":null,"affectedPackages":[],"fix":null,"references":[{"type":"WEB","url":"https://github.com/frappe/frappe/releases/tag/v15.115.0"},{"type":"WEB","url":"https://github.com/frappe/frappe/security/advisories/GHSA-p25m-7rvg-6fvr"}],"provenance":{"sources":["OSV.dev","NVD","FIRST.org (EPSS)"],"lastVerified":"2026-08-26T20:17:56.920"}}
