JavaScript execution via unescaped form attributes
Published Feb 20, 2026 · Updated Feb 20, 2026
DOM-based XSS in calliko NPS computy 2.8.2 and earlier allows remote attackers to run JavaScript via crafted form values. The administrative form generator inserts date-range and poll-name values directly into HTML value attributes without attribute escaping. Exploitation requires a victim to render the crafted values; the resulting script executes in the victim's browser and inherits that session's access.
