Project Manager WordPress plugin lets anyone run code on the server

A WordPress plugin for managing projects has a flaw that lets people with no login run commands on the website's server. That can let them take over the site and its data.

How the attack works simplified

  1. 1Unauthenticated attackerNo login or account needed
  2. 2Crafted REST requestSends malicious 'id' value to plugin route
  3. 3WordPress runs validationvalidate_callback runs before permission check
  4. 4PHP functions invokedPipe-split tokens called as dynamic functions
  5. ResultAttacker executes code on the server

What happened

The 'id' parameter in the plugin's REST route is concatenated into a pipe-delimited validation rule string, which is split and each token invoked as a PHP function without an allowlist, enabling unauthenticated remote code execution. WordPress runs the route's validate_callback before the permission_callback, so the plugin's capability check is never reached.

Why it is dangerous: An unauthenticated attacker can execute code on the server, potentially gaining full control of the site and its data. Any site running the affected plugin is at risk.

Are you affected?

You are affected if you run The Project Manager – AI Powered Project Management, Task Management, Kanban Board & Time Tracker plugin for WordPress version 4.1.1 or earlier.

The Project Manager (WordPress plugin) all versions up to and including 4.1.1

What to do

  1. Check whether the Project Manager plugin is installed and what version it is
  2. Update the plugin to a version newer than 4.1.1 if one is available; the sources provided do not name a fixed version
  3. If no fix is available, deactivate and remove the plugin, or restrict access to its REST endpoints at the web server or firewall level
  4. Review the server for unexpected files, accounts, or processes if the plugin was exposed
