Stored XSS via unsanitized private-task descriptions

Published May 4, 2023 · Updated Jan 29, 2025

Stored XSS in TotalJS Messenger commit b6cf1c9 allows remote authenticated users to execute scripts through private tasks. The application stores a task-description payload and renders it as executable page content without neutralizing embedded HTML or script. Another user must view the saved task; the payload then runs in that user's browser and can read or alter data accessible to the page.
