CVE-2026-2021Slideshow Gallery LITE <= 1.8.5 - Authenticated (Contributor+) Stored Cross-Site Scripting via 'alwaysauto' Shortcode Attribute

contrid Slideshow Gallery LITE Veröffentlicht: 2026-06-18 11:31 (vor 4 Monaten)

Beschreibung

The Slideshow Gallery LITE plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'alwaysauto' shortcode attribute in all versions up to, and including, 1.8.5. This is due to insufficient input sanitization and output escaping on user-supplied attributes. 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.
