Description

The Spectra – WordPress Gutenberg Blocks plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the ‘block_id’ parameter in versions up to, and including, 2.13.0 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with author-level permissions and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.

Affected products

• Brainstorm Force Spectra: before 2.13.1 — fixed in 2.13.1

How to fix

Upgrade to a fixed version: Brainstorm Force Spectra 2.13.1. Check the vendor advisory for mitigations.
