WordPress · Events Manager · CVE-2026-12987
**Name of the Vulnerable Software and Affected Versions**
Events Manager versions prior to 7.3.7
**Description**
On sites using No-User-Account Booking Mode, the software fails to safely handle booking-registration data. A registration field supplied by a booker is stored as booking meta and subsequently deserialized without restricting allowed classes, which enables PHP object injection. This process creates a gadget chain that leads to a database query constructed without parameterization, allowing an unauthenticated attacker to read arbitrary database data, such as secret keys and user password hashes, when the booking is loaded.
**Recommendations**
Update Events Manager to version 7.3.7 or later.
