CVE-2026-16290: Unknown Profilegrid

Medium severity, CVSS 5.3. EPSS: 0.4% chance of exploitation in the next 30 days.

The ProfileGrid WordPress plugin before 6.0.0.0 does not perform authorization checks before returning a group's member list, and registers the handler for unauthenticated users, allowing any unauthenticated visitor to disclose the members and their identifiers of any group, including private or closed ones, bypassing the ProfileGrid WordPress plugin before 6.0.0.0's member-visibility setting.

Affected products
