Vulnerability from github – Published: 2026-02-26 22:22 – Updated: 2026-02-26 22:22Privilege Escalation to Admin via User Self-Update in wg-portal
Summary
Any authenticated non-admin user can become a full administrator by sending a single PUT request to their own user profile endpoint with "IsAdmin": true in the JSON body. After logging out and back in, the session picks up admin privileges from the database.
Tested against wg-portal v2.1.2 (Docker image wgportal/wg-portal:v2).
Root Cause
When a user updates their own profile, the server parses the full JSON body into the user model, including the IsAdmin boolean field. A function responsible for preserving calculated or protected attributes pins certain fields to their database values (such as base model data, linked peer count, and authentication data), but it does not do this for IsAdmin. As a result, whatever value the client sends for IsAdmin is written directly to the database.
Impact
After the exploit, the attacker has full admin access to the WireGuard VPN management portal. They can:
- Read and modify every user account
- Create, modify, and delete WireGuard peers on any interface
- View WireGuard interface configurations
- Disable or lock other user accounts
- Access the full user list and their API tokens
Patches
The problem was fixed in the latest release, v2.1.3. The docker images for the tag 'latest' built from the master branch also include the fix.

Mitigation MIT-1
Very carefully manage the setting, management, and handling of privileges. Explicitly manage trust zones in the software.
Mitigation MIT-48
Strategy: Separation of Privilege
Follow the principle of least privilege when assigning access rights to entities in a software system.
Mitigation MIT-49
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.
