Option overwrite and secret disclosure via unsafe deserialization
Published Sep 27, 2026 · Updated Sep 27, 2026
PHP object injection in Ladela Interactive Bookly 23.2 through 28.2 allows remote authenticated users to alter options and read secrets. The Diagnostics Advanced Options maintenance feature deserializes attacker-controlled input without enforcing administrator-only access. Exploitation requires an explicitly assigned booking-management capability and permits arbitrary object injection, privileged option changes, and access to stored integration secrets.
