Technical details

A persistent HTML injection vulnerability in TinyMCE-managed editable fields fails to sanitize attacker-controlled input before storing it in the database. An authenticated attacker with low privileges can inject unsanitized HTML that is rendered in other users' browsers, leading to stored XSS. The vulnerability requires authentication and user interaction (victim viewing the affected content), and allows defacement and session hijacking.
