Unintended operations via invariant CSRF token
Published May 13, 2026 · Updated May 13, 2026
Cross-site request forgery in affected ELECOM WAB access points allows remote attackers to perform unintended administrative operations. The web administration interface accepts an invariant CSRF token rather than tying a changing token to the authenticated session or request. Exploitation requires a logged-in user to visit an attacker-controlled page, and the documented consequence is unauthorized device operations without data disclosure or service interruption.
