**Name of the Vulnerable Software and Affected Versions** The Counter Box: Add Engaging Countdowns, Timers & Counters to Your WordPress Site plugin for WordPress versions up to, and including, 2.0.6 **Description** The issue is related to DOM-Based Stored Cross-Site Scripting due to insufficient input sanitization and output escaping, specifically via the `content` parameter. This allows authenticated attackers with administrator-level access to inject arbitrary web scripts in pages, which will execute when a user accesses an injected page. The issue only affects multi-site installations and installations where unfiltered html has been disabled. **Recommendations** For versions up to, and including, 2.0.6, update to a version that addresses the insufficient input sanitization and output escaping issue to prevent DOM-Based Stored Cross-Site Scripting attacks.

**Name of the Vulnerable Software and Affected Versions** Modal Portfolio plugin for WordPress versions up to, and including, 1.7.4.2 **Description** The issue is related to Stored Cross-Site Scripting due to insufficient input sanitization and output escaping. This allows authenticated attackers with Administrator-level access and above to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. The issue only affects multi-site installations and installations where unfiltered html has been disabled. **Recommendations** For versions up to, and including, 1.7.4.2, update to a version that includes the necessary input sanitization and output escaping fixes to prevent Stored Cross-Site Scripting attacks.

**Name of the Vulnerable Software and Affected Versions** NotificationX – Live Sales Notification, WooCommerce Sales Popup, FOMO, Social Proof, Announcement Banner & Floating Notification Top Bar plugin for WordPress versions up to, and including, 2.9.3 **Description** The issue is related to Stored Cross-Site Scripting via the plugin's content settings for notifications due to insufficient input sanitization and output escaping. This allows authenticated attackers with administrator-level permissions and above to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. The issue only affects multi-site installations and installations where unfiltered html has been disabled. **Recommendations** For versions up to, and including, 2.9.3, update to a version that includes the necessary input sanitization and output escaping fixes to prevent Stored Cross-Site Scripting attacks. As a temporary workaround, consider restricting access to the plugin's content settings for notifications to minimize the risk of exploitation. Additionally, ensure that unfiltered html is enabled, if possible, to reduce the attack surface.
