What is CVE-2026-12987?

CVE-2026-12987 is a high-severity SQL injection vulnerability in Unknown Events Manager, published on 22 Jul 2026. An attacker can exploit it over the internet without logging in, with no action from the victim.

Official description

The Events Manager WordPress plugin before 7.3.7 does not safely handle booking-registration data on sites using No-User-Account Booking Mode: a booker-supplied registration field is stored as booking meta and later deserialized without restricting allowed classes, enabling PHP object injection. The resulting gadget chain reaches a database query that is built without parameterisation, so an unauthenticated attacker can read arbitrary database data (e.g. user password hashes, secret keys) when the booking is later loaded.

Weakness: CWE-89
