• Severity: medium (CVSS 6.4 v3.1)
• Exploited in the wild: not listed in CISA KEV
• EPSS: 0.2% probability of exploitation in the next 30 days
• Public exploit or detection template: none known
• Published: 2026-02-19 · updated 2026-06-17
• Weakness: CWE-79

Description

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.

Affected products

• Dealia – Request a quote: through 1.0.8
