CVE-2026-62233: Authorization Bypass Through User-Controlled Key in getgrav grav
A vulnerability in grav-plugin-api before version 1.0.6 allows non-super-admin users with api.users.write permissions to escalate their privileges to super-admin. This occurs because the plugin fails to properly validate super-admin status in the createApiKey, generate2fa, and disable2fa endpoints. Exploiting this flaw, attackers can create API keys tied to super-admin accounts or disable two-factor authentication for super-admin users, potentially leading to full instance takeover.
AI Analysis
Technical Summary
CVE-2026-62233 is an authorization bypass vulnerability in grav-plugin-api versions prior to 1.0.6. The flaw arises from insufficient validation of super-admin status in key API endpoints (createApiKey, generate2fa, disable2fa). This allows users with api.users.write privileges but without super-admin rights to escalate their privileges by minting API keys bound to super-admin accounts or disabling two-factor authentication for super-admin users. The vulnerability has a CVSS 4.0 base score of 8.7, indicating high severity. No official remediation or patch information is currently provided.
Potential Impact
Successful exploitation enables attackers with limited privileges to escalate to super-admin level, granting full control over the grav instance. This includes the ability to generate API keys with super-admin privileges and disable two-factor authentication for super-admin accounts, significantly increasing the risk of full system compromise.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, restrict api.users.write permissions to fully trusted users only and monitor for suspicious activity related to API key creation and two-factor authentication changes.
