CVE-2025-12672: Nuvuscripts Flickr Show

Medium severity, CVSS 6.4. EPSS: 0.2% chance of exploitation in the next 30 days.

The Flickr Show plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'div_height' parameter of the 'flickrshow' shortcode in all versions up to, and including, 1.5 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.

Affected products

• Nuvuscripts Flickr Show: up to and including 1.5
