CVE-2026-15299 wealcoder CVE debrief

Who should care

Users of the Animation Addons for Elementor plugin for WordPress, particularly those with Contributor-level access or above, should be aware of this vulnerability and take steps to mitigate it. This includes updating the plugin to version 2.6.4 or later, validating and sanitizing user input, and implementing output escaping for the Weather widget's render() function. Additionally, users should review compensating controls, monitor for exposed assets, and track exceptions to ensure the vulnerability is properly addressed.

Technical summary

The Animation Addons for Elementor plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'weather_style' and 'move_direction' parameters of the Weather widget in all versions up to, and including, 2.6.3. This is due to insufficient output escaping in the Weather widget's render() function at widgets/weather.php:1246, where both settings values are placed into an HTML class attribute without esc_attr(). Elementor does not server-side validate widget SELECT control values against allowed options on save, so an authenticated attacker with Contributor-level access or above can submit a crafted save_builder AJAX request storing arbitrary values in the _elementor_data post meta.

Defensive priority

Medium

Recommended defensive actions

• Update the Animation Addons for Elementor plugin to version 2.6.4 or later
• Validate and sanitize user input for the Weather widget's 'weather_style' and 'move_direction' parameters
• Implement output escaping for the Weather widget's render() function
• Review compensating controls for exposed systems while remediation is scheduled and verified
• Check relevant monitoring, detection, and logs for exposed assets that need extra review
• Track exceptions, retest remediated assets, and close the item only after evidence is documented
• Confirm whether affected product deployments exist in managed environments and assign an owner for follow-up
