Session script execution via developer-console payload
Published Nov 5, 2025 · Updated Nov 5, 2025
DOM-based XSS in SelfBest platform 2023.3 allows attackers to execute JavaScript in a logged-in user's session through the browser console. The public record does not identify the DOM source or sink; it states that client-side code permits direct DOM manipulation without sanitization or a restrictive Content Security Policy. Exploitation requires a logged-in user to run the payload in developer tools, after which it can access or alter data available to that session.
