CVE-2026-56710 PUBLISHED

Grav Login Plugin before 1.0.16 Privilege Escalation via Unlock

Assigner: VulnCheck
Reserved: 22.06.2026 Published: 25.08.2026 Updated: 25.08.2026

Grav Login plugin versions before 1.0.16 fail to validate the target account's privilege level in the onApiUserListRowAction unlock handler. An attacker with api.users.write permission can clear login lockout counters on admin.super accounts, removing brute-force protection from the highest-privilege accounts without requiring equivalent permissions.
