description

Masteriyo - LMS versions through 3.4.0 are affected by unsafe deserialization that can lead to PHP object injection. A remote attacker may trigger object injection without signing in, according to the advisory.

mitigation

Disable the Masteriyo - LMS plugin on internet-accessible sites, or restrict access to trusted networks until an update is available. No fixed release is recorded; monitor the vendor for a patched version and upgrade promptly.
