CVE-2026-84279Fancy Product Designer <= 6.5.2 - Unauthenticated Stored Cross-Site Scripting via 'output_format' Parameter via Pro Export Print Job
High 7.2
In plain English
A high-severity cross-site scripting in Fancy Product Designer from radykal. There are no confirmed reports of exploitation so far. The chance it is exploited in the next 30 days is estimated at 0.2% (higher than 9% of all known vulnerabilities).
Official description
The Fancy Product Designer plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'output_format' parameter in all versions up to, and including, 6.5.2 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. This requires the Pro Export/Genius feature to be enabled on the site, as the vulnerable fpd_pr_export AJAX action is only registered when that feature is active.
