Summary

Frappe before 14.59.0 and 15.x before 15.5.0 contain a sandbox flaw where the frappe.flags.in_safe_exec flag can become False during Server Script execution when one server script triggers another. CWE-372 covers this incomplete internal state distinction. An authenticated high-privileged user 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.

Description from the CNA

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.
