  • Severity: medium-risk
  • Status: Fixed
  • Publication: March 25, 2025

The Spectra – WordPress Gutenberg Blocks plugin for WordPress has a security issue that can be exploited by attackers. This can happen through a feature called “uagb block” and affects all versions up to 2.19.0. This is due to a lack of proper protection against harmful inputs and outputs. As a result, attackers who have Contributor-level access or higher can insert malicious web scripts into pages. These scripts will then run when a user visits the affected page.
