Stored XSS via unsanitized callback parameters

Published Jun 3, 2023 · Updated Apr 8, 2026

Stored XSS in vcita CRM and Lead Management 2.6.2 and earlier allows remote authenticated users to inject scripts through the email parameter. The vcita-callback.php endpoint stores the email query value without validation, and the settings page emits it without output escaping. Contributor-level edit_posts access is sufficient, and the stored script runs when a user opens the affected settings page.
