Executive Summary

CVE-2026-50701 is a Reflected Cross-Site Scripting (XSS) vulnerability found in Frappe Framework version 17.0.0-dev. It occurs because the dashboard-view component improperly neutralizes user-controlled input.

Specifically, the vulnerability arises in the breadcrumb rendering logic where route data is read directly from the browser URL and injected into the page without proper encoding or sanitization.

An attacker can craft a malicious URL containing HTML or JavaScript in a route segment, which is then decoded and inserted into the DOM via jQuery HTML parsing without escaping. This causes the injected content to be executed as active markup rather than displayed as plain text.

Detection Guidance

The vulnerability can be detected by checking if the Frappe Framework version 17.0.0-dev is in use and if the dashboard-view component improperly neutralizes user-controlled input in the breadcrumb rendering logic.

Detection involves verifying whether the system reads route data directly from the browser URL and injects it into the page without adequate output encoding or sanitization.

A practical approach is to test for reflected XSS by crafting a malicious URL containing HTML or JavaScript within a route segment and observing if it is executed in the victim's session.

Specific commands are not provided in the available resources.

Mitigation Strategies

As of the disclosure date, there is no available patch for this vulnerability.

Immediate mitigation steps include avoiding the use of untrusted or user-controlled input in URLs that affect the dashboard breadcrumb rendering.

Implement input validation and output encoding or sanitization on the route data before it is injected into the DOM.

Consider restricting access to the affected component or applying web application firewall (WAF) rules to detect and block malicious payloads in URLs.
