SCA: security update for github.com/h44z/wg-portal (GHSA-5rmx-256w-8mj9)

high Tenable Self-Hosted Container Security Plugin ID 438111

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - WireGuard Portal (or wg-portal) is a web-based configuration portal for WireGuard server management. Prior
 to version 2.1.3, 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. 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. After the exploit, the attacker has full admin access to the WireGuard VPN management portal.
 The problem was fixed in v2.1.3. The docker images for the tag 'latest' built from the master branch also
 include the fix. (CVE-2026-27899)
