CVE-2026-50026Network attack vector

Unauthorized resource modification via unchecked endpoints

Published Jun 12, 2026 · Updated Jun 12, 2026

Missing authorization in Frappe Framework before 15.107.0 and 16.17.0 allows remote attackers to modify protected resources. The whitelisted relink endpoint updated a Communication record's document links without checking write permission, while set_email_password changed an Email Account's stored password without verifying authorization. No credentials or user interaction are required; successful requests can alter communication links or replace an email-account credential, but the published record reports no availability impact.
