CVE-2026-31878Network attack vector

Authenticated SSRF via crafted endpoint request

Published Mar 11, 2026 · Updated Mar 11, 2026

SSRF in Frappe Framework before 14.100.1, 15.100.0, and 16.6.0 allows remote authenticated users to trigger arbitrary HTTP calls. A crafted request to an undisclosed endpoint makes the server call a requester-selected service, but no endpoint name or failed validation is public. Any authenticated account can reach the flaw without user interaction, enabling access through the server's network position without reported data modification or service interruption.
