CVE-2026-12687: Unknown Profilegrid

High severity, CVSS 7.5. EPSS: 0.4% chance of exploitation in the next 30 days.

The ProfileGrid WordPress plugin before 5.9.9.8 does not restrict which group an anonymous visitor may register into through its front-end registration, allowing unauthenticated users to register directly into a privileged group and be granted that group's configured role, up to Administrator when such a group exists, leading to privilege escalation.

Affected products

• Unknown Profilegrid: before 5.9.9.8 (fixed in 5.9.9.8)
