Unauthenticated token replacement via unguarded init handler
Published Jun 19, 2024 · Updated Apr 28, 2026
Missing authorization in ServMask All-in-One WP Migration extensions allows remote attackers to replace or delete storage access tokens. Each extension's init handler copies an unauthenticated wp-ajax request parameter into its token option without a capability check or nonce validation. No account or user interaction is required; token replacement can redirect exported backups to attacker-controlled storage, while deletion interrupts configured cloud access.
