Stored XSS via unneutralized client names
Published Dec 2, 2022 · Updated Jul 9, 2026
Stored XSS in webtareas 2.4p5 allows remote authenticated users to execute arbitrary scripts in another user's browser. The clients/listclients.php workflow stores a crafted Name value and later renders event-handler markup without effective neutralization. Exploitation requires permission to add a client and a victim to view the stored entry, placing that victim's browser session in the attacker's script context.
