What is CVE-2023-54406?
CVE-2023-54406 is a medium-severity vulnerability in frappe, published on 12 Oct 2026. An attacker needs administrator access to exploit it, with no action from the victim.
Official 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.
