# ProfilePress WordPress plugin: unauthenticated users can join deactivated membership plans

Link for people: https://infrastack.ai/live/CVE-2026-123657 (this .md is for agents)

The ProfilePress WordPress plugin before 4.17.6 does not reject negative membership plan identifiers before checking whether a plan is active. An unauthenticated visitor can therefore sign up for a plan an administrator has deactivated and receive the role attached to it.

_Summary, check and fix written by a model from the sources; labelled as such._

## How to check

- Check the installed ProfilePress version in the WordPress plugins list or the plugin's main file header; versions before `4.17.6` are listed in the description as affected.
- Review membership plans for any deactivated plan that still grants a role.

## Fix

- ProfilePress `4.17.6` or later (the sources name `4.17.6` as the first fixed version).

## Timeline

## From the sources

The ProfilePress  WordPress plugin before 4.17.6 does not reject negative membership plan identifiers before checking whether a plan is active, allowing unauthenticated visitors to sign up for membership plans an administrator has deactivated and receive the role attached to them.
