description

Advanced Post Manager versions through 4.5.5 contain an unsafe deserialization flaw that can allow object injection. An attacker does not need prior privileges according to the advisory metadata; resulting impact depends on the objects and code present in the affected WordPress installation.

mitigation

Disable Advanced Post Manager on exposed sites until the vendor provides a confirmed corrected release. Restrict unauthenticated access to affected installations where disabling the plugin is not immediately possible.
