CVE-2026-12687: CWE-269 Improper Privilege Management in ProfileGrid
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.
AI Analysis
Technical Summary
CVE-2026-12687 is an improper privilege management vulnerability (CWE-269) in the ProfileGrid WordPress plugin prior to version 5.9.9.8. The plugin does not restrict which group an anonymous visitor may register into through its front-end registration feature. As a result, unauthenticated users can register directly into privileged groups and gain the roles assigned to those groups, including Administrator, leading to privilege escalation.
Potential Impact
An attacker can escalate privileges from an unauthenticated state to a privileged role, potentially Administrator, by registering into a privileged group via the front-end registration. This compromises the integrity and security of the WordPress site by granting unauthorized administrative access.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, restrict or disable front-end registration or carefully configure group permissions to prevent anonymous registration into privileged groups.
