CVE-2026-2718

Dealia <= 1.0.8 - Authenticated (Contributor+) Stored Cross-Site Scripting via Gutenberg Block Attributes

6.4 Medium

The Dealia – Request a Quote plugin for WordPress is vulnerable to Stored Cross-Site Scripting via Gutenberg block attributes in all versions up to, and including, 1.0.8. This is due to the use of wp_kses() for output escaping within HTML attribute contexts where esc_attr() is required. 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.
