Authenticated script execution via unsanitized date fields
Published May 22, 2025 · Updated May 22, 2025
DOM-based XSS in Intermesh BV GroupOffice before 6.8.119 and before 25.0.20 allows remote authenticated users to execute JavaScript. A date input field inserts an authenticated user's crafted value into the DOM without sanitization, allowing an img onerror handler to run. Exploitation requires login and a victim to render the injected field; code runs in that victim's browser context and can access session data or act as the victim.
