What is CVE-2026-4665?

The WP Carousel Free plugin for WordPress contains a vulnerability that allows authenticated attackers with Contributor-level access to inject arbitrary scripts into web pages. This occurs through the improper handling of the data-caption attribute in the fancybox integration. When a malformed carousel container ID is crafted, it leads to a failure in initializing the custom fancybox configuration, causing it to default to handling the data-caption content as raw HTML. Consequently, this allows the execution of malicious scripts when users interact with the carousel's images.

Affected Version(s)

Carousel, Slider, Photo Gallery with Lightbox, Video Slider, by WP Carousel 0 <= 2.7.10
