CVE-2025-1439: Tinywebgallery Advanced Iframe

Medium severity, CVSS 5.4. EPSS: 0.2% chance of exploitation in the next 30 days.

The Advanced iFrame plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the plugin's 'advanced_iframe' shortcode in all versions up to, and including, 2024.5 due to insufficient input sanitization and output escaping on user supplied attributes through the 'src' attribute when the src supplied returns a header with an injected value . 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

• Tinywebgallery Advanced Iframe: before 2025.0 (fixed in 2025.0)
