Reflected XSS via unescaped administrative output
Published Feb 20, 2026 · Updated Feb 20, 2026
Reflected XSS in Link Whisper Free 0.9.2 and earlier allows remote attackers to execute scripts via a crafted request. On the AI subscription administration page, attacker-controlled identifiers are written into HTML attributes without context-appropriate escaping. An unauthenticated attacker must persuade a logged-in administrator to open the crafted link; the script then runs in that administrator's browser context.
