CyberRota Analysis
AI-GeneratedGrav CMS versions 2.0.14 to 2.0.24 are vulnerable to a privilege escalation flaw that allows authenticated users with limited admin rights to elevate their privileges to super-admin status. This vulnerability can be exploited by manipulating access keys, enabling attackers to gain full control over the system, including configuration and account management. Organizations using affected versions should prioritize upgrading to 2.0.25 to mitigate this significant security risk.

Original NVD Description
Grav CMS 2.0.14 through 2.0.24 contains a privilege escalation vulnerability in the group and account blueprints. The access map is gated by a `security@: admin.super` guard that is resolved by the field's exact path, so a submitted flat dot-notation key such as `access.admin.super` (instead of the nested `access[admin][super]`) matches no blueprint rule, survives BlueprintSchema::filterArray() and flattening, and is written by FlexObject::update() via setNestedProperty(), which splits on `.` and reconstructs the nested value. An authenticated backend operator using the flex accounts backend who holds admin.users but not admin.super can therefore grant admin.super to their own account or to a group they belong to and escalate to full super-admin, gaining control over configuration, plugin and theme installation, the file manager, and all accounts. Fixed in 2.0.25, which drops any dotted key whose ancestor path is disabled or marked validate.ignore.
