CVE-2026-5191Network attack vector

Stored XSS via unescaped image title attribute

Published Jun 2, 2026 · Updated Jun 2, 2026

Stored XSS in ThemePacific Tiled Gallery Carousel Without JetPack 3.1 and earlier allows remote authenticated users to inject scripts. The carousel's data-image-title attribute accepts attacker-controlled image-title content without adequate sanitization and emits it without context-appropriate escaping. Contributor-level access is required, and the injected JavaScript runs when a user opens the affected page, enabling actions in that user's browser context.
