CVE-2026-4805: Woostify plugin allows contributors to add malicious scripts
CVE-2026-4805 · published 6 months ago
Summary
The Woostify add‑on for WordPress (versions up to 2.5.0) does not properly clean certain input, so a user with contributor or higher rights can place code that runs in other visitors' browsers. This could let an attacker show false information, steal data, or hijack sessions when a victim views the altered page. Update the plugin to a newer version or remove the vulnerable feature until a fix is applied.
Original advisory text
Woostify <= 2.5.0 - Authenticated (Contributor+) Stored Cross-Site Scripting via Lity.js Library via data-lity Attribute in Custom HTML Block
The Woostify plugin for WordPress is vulnerable to Stored Cross-Site Scripting in versions up to, and including, 2.5.0 This is due to insufficient input sanitization and output escaping in the bundled Lity.js lightbox library, where user-controlled input from the href attribute is concatenated directly into a jQuery HTML string without sanitization. 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.
