CVE-2023-54406

Frappe before 14.59.0 Safe Execution Flag Bypass in Server Scripts

Published Oct 12, 2026 CVSS 4.0 · 6.9 Medium EPSS < 1% KEV · Not listed
Description
Frappe before 14.59.0 and 15.x before 15.5.0 contains a sandbox flaw where the frappe.flags.in_safe_exec global flag can become False during Server Script execution when one server script triggers another. Authenticated high-privileged users can craft a Server Script that triggers other server scripts, such as by saving a document, so the remaining code runs without safe execution protections.
