WordPress · The Slider · CVE-2025-5337
**Name of the Vulnerable Software and Affected Versions**
The Slider, Gallery, and Carousel by MetaSlider plugin for WordPress versions up to, and including, 3.98.0
**Description**
The issue is related to Stored Cross-Site Scripting due to insufficient input sanitization and output escaping, specifically via the `aria-label` parameter. This allows authenticated attackers with Contributor-level access and above to inject arbitrary web scripts in pages, which will execute when a user accesses an injected page.
**Recommendations**
For versions up to, and including, 3.98.0, update to a version that addresses the insufficient input sanitization and output escaping issue.
As a temporary workaround, consider restricting access to the `aria-label` parameter to minimize the risk of exploitation.
