Contributor-level stored XSS via unsanitized page content
Published Nov 19, 2024 · Updated May 11, 2026
Stored cross-site scripting in DemixPress (dp) AddThis 1.0.2 and earlier allows remote authenticated users to inject web scripts. Public records identify insufficient input sanitization and output escaping but do not name the vulnerable field, parameter, or function. Contributor-level access is required, and the stored script executes when another user opens the injected page, exposing that browser session to attacker-controlled actions.
