Name of the Vulnerable Software and Affected Versions The Spectra – WordPress Gutenberg Blocks plugin versions up to, and including, 2.19.0

Description The issue is related to Stored Cross-Site Scripting via the uagb block due to insufficient input sanitization and output escaping. This allows authenticated attackers with Contributor-level access and above to inject arbitrary web scripts in pages, which will execute whenever a user accesses an injected page.

Recommendations For versions up to, and including, 2.19.0, update to a version that includes the necessary input sanitization and output escaping fixes to prevent Stored Cross-Site Scripting attacks. As a temporary workaround, consider restricting access to the uagb block for users with Contributor-level access and above until a patch is available.
