CVE-2025-12672

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.
