Vulnerability from github – Published: 2026-05-05 21:29 – Updated: 2026-05-13 13:52
VLAI
Summary
Grav Vulnerable to Administrative Account Disruption and Privilege De-escalation via User Overwrite Logic
Details

Summary

A business logic vulnerability in the Grav Admin Panel allows a low-privileged user (with only user creation permissions) to overwrite existing accounts, including the primary administrator. By creating a new user with a username that already exists, the system updates the existing account's metadata and permissions instead of rejecting the request. This leads to a Denial of Service (DoS) on administrative functions and Privilege De-escalation of the root account.

Details

The vulnerability stems from an insecure "Create or Update" logic within the user management module. When the admin-addon handles a user creation request, it does not strictly validate whether the username is already taken by a higher-privileged account. Instead of returning a "409 Conflict" or a validation error, the application logic proceeds to overwrite the existing user configuration file (e.g., user/accounts/root0.yaml) with the new, lower-privileged data provided by the attacker. Because the attacker cannot assign higher permissions to themselves (due to existing fixes), the result is that the targeted account (the original Admin/Root) has its access levels wiped or replaced by the attacker's input, effectively locking the real administrator out of the system.

PoC

  1. Log in as a Super User (e.g., root0) and create a low-privileged user (e.g., adminuser).
  2. Assign adminuser the following specific permissions: admin.login admin.users.list admin.users.read admin.users.create
  3. Log out and log back in as adminuser.
  4. Navigate to User Accounts -> Add.
  5. Fill in the form with the following details: Username: root0 (The exact username of the Super User) Email: anything@grav.f Fullname: Fake Root0
  6. Click Save.
  7. Observe that the account is successfully "created".
  8. The original administrative permissions are gone, and the account is now restricted.

Impact

This is a Privilege De-escalation and Account Disruption vulnerability. Who is impacted: Any Grav installation where a non-admin user is granted permission to create other users. Consequence: An attacker can effectively disable all administrative accounts on the platform, leading to a complete loss of management control over the CMS.

Maintainer note — fix applied (2026-04-24)

Fixed in Grav core on the 2.0 branch: commit d904efc33 — will ship in 2.0.0-beta.2.

What changed: UserObject::save already had a uniqueness guard (commit 19c2f8da7, November 2025) that blocks the PoC. This release tightens that guard:

  1. strpos($key, '@@') → str_contains($key, '@@'). The previous form was falsy when the transient-key marker was at position 0 (e.g. @@hash), silently bypassing the check. str_contains returns a proper boolean.
  2. The instanceof FileStorage gate was dropped so the uniqueness check runs for any FlexStorageInterface backend — not just the default file-per-user YAML one.

A low-privileged user with admin.users.create can no longer disrupt a super-admin account by submitting that admin's username through the "add user" form.

Files: - system/src/Grav/Common/Flex/Types/Users/UserObject.php. - tests/unit/Grav/Common/Security/UserOverwriteSecurityTest.php — 3 tests pinning the PoC, the @@-prefix edge case, and pass-through for free usernames.

Mitigation MIT-1
Architecture and Design Operation

Very carefully manage the setting, management, and handling of privileges. Explicitly manage trust zones in the software.

Mitigation MIT-48
Architecture and Design

Strategy: Separation of Privilege

Follow the principle of least privilege when assigning access rights to entities in a software system.

Mitigation MIT-49
Architecture and Design

Strategy: Separation of Privilege

Consider following the principle of separation of privilege. Require multiple conditions to be met before permitting access to a system resource.

CAPEC-122: Privilege Abuse

An adversary is able to exploit features of the target that should be reserved for privileged users or administrators but are exposed to use by lower or non-privileged accounts. Access to sensitive information and functionality must be controlled to ensure that only authorized users are able to access these resources.

CAPEC-233: Privilege Escalation

An adversary exploits a weakness enabling them to elevate their privilege and perform an action that they are not supposed to be authorized to perform.

CAPEC-58: Restful Privilege Elevation

An adversary identifies a Rest HTTP (Get, Put, Delete) style permission method allowing them to perform various malicious actions upon server data due to lack of access control mechanisms implemented within the application service accepting HTTP messages.
