Unauthorized action via missing update-check nonce validation
Published Oct 9, 2023 · Updated Apr 28, 2026
CSRF in QuantumCloud WPBot 4.7.8 and earlier allows remote attackers to invoke an update-check action through a forged request. The qc_wp_latest_update_check function processes the request without correct WordPress nonce validation, permitting an attacker-selected invocation. Exploitation requires a site administrator to act on attacker-controlled content; the precise resulting data change is not publicly described.
