Alert meAnalysisAIv1 – Mar 15, 2026
Grav is a file-based Web platform. Prior to 1.8.0-beta.27, a privilege escalation vulnerability exists in Grav’s Admin plugin due to the absence of username uniqueness validation when creating users. A user with the create user permission can create a new account using the same username as an existing administrator account, set a new password/email, and then log in as that administrator. This effectively allows privilege escalation from limited user-manager permissions to full administrator access. This vulnerability is fixed in 1.8.0-beta.27.

RemediationAI
A vendor patch is available — apply it immediately. Apply the principle of least privilege. Keep systems patched. Monitor for suspicious privilege changes. Use mandatory access controls (SELinux, AppArmor).

Lifecycle Timeline
2Executive ViewAI
A privilege escalation vulnerability in Grav's Admin plugin allows users with limited permissions to create duplicate administrator accounts and gain full system access. Organizations running Grav prior to version 1.8.0-beta.27 face immediate risk of unauthorized administrative control over their web platform and content.
Apply vendor patch. Interim mitigations if patching is delayed: restrict create user permissions to trusted administrators only, implement Web Application Firewall rules to block unusual user creation API calls, and enable comprehensive audit logging for all user management activities.
