CVE-2026-5254 Details
Description
A security vulnerability has been detected in welovemedia FFmate up to 2.0.15. Affected by this issue is some unknown functionality of the file /ui/app/components/AppJsonTreeView.vue of the component Webhook Handler. The manipulation leads to cross site scripting. The attack may be initiated remotely. The exploit has been disclosed publicly and may be used. The vendor was contacted early about this disclosure but did not respond in any way.
A stored cross-site scripting (XSS) vulnerability exists in welovemedia FFmate versions through 2.0.15. The issue arises in the Webhook Handler component, specifically within the AppJsonTreeView.vue file. Webhook responses are stored and displayed without proper sanitization, allowing malicious JavaScript payloads to execute in the browsers of users viewing the webhook execution results. This vulnerability could lead to session hijacking, credential theft, or unauthorized actions performed on behalf of victims.
It is recommended to implement HTML sanitization, avoid using 'v-html' in Vue.js, apply Content Security Policy headers, and validate input against a whitelist of allowed HTML tags and attributes.
