Stored XSS via unsanitized comment and brand fields
Published Jan 29, 2026 · Updated Jan 29, 2026
Stored XSS in PlanManager all versions allows remote authenticated users to execute JavaScript in another user's browser. The /index.php handler stores the comment and brand parameters and later renders those values to other users without sanitization. Exploitation requires low-privilege access and passive victim interaction, enabling session-cookie theft or actions within the victim's browser session.
