CVE-2026-15798

MEDIUM NVD
CVSS Score 6.4
Severity MEDIUM
Published Aug 28, 2026
Vendor unknown

Description

The Smart Slider 3 plugin for WordPress is vulnerable to Stored Cross-Site Scripting via 'slider' Block Attribute in all versions up to, and including, 3.5.1.38 due to insufficient input sanitization and output escaping. 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. The injected scripts execute specifically when a user opens the affected post in the WordPress block editor, making Editors and Administrators the primary targets.
