CVE-2023-54408 · Severity: medium · CVSS 6.1 · Published 2026-10-12

Frappe is a web application framework used to build enterprise resource planning (ERP) and business management systems. A vulnerability in how user-supplied content is escaped allows attackers to inject malicious HTML that executes as JavaScript in other users' browsers, potentially leading to account takeover or credential theft. An attacker can exploit this by submitting crafted HTML through the application that bypasses security checks and runs in the context of users viewing the affected content.
