Administrator-level stored XSS via unsanitized redirect settings
Published May 10, 2023 · Updated Apr 28, 2026
Stored XSS in Premmerce Redirect Manager 1.0.9 and earlier allows remote authenticated users with administrator access to inject scripts. The redirect-management settings accept input without sufficient sanitization and render it without sufficient output escaping. Exploitation requires administrator-level access and affects multisite installations or sites where unfiltered_html is disabled; scripts run when a user opens the injected page.
