The Advance Block Extend plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the TitleColor block attribute in the Latest Posts Gutenberg block in all versions up to, and including, 1.0.4 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with Contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
