CVE-2026-97396Network attack vector

Subscriber-level stored XSS via unsanitized option data

Published Oct 10, 2026 · Updated Oct 10, 2026

Retainful 1.0.10 and earlier has stored XSS allowing remote authenticated users to inject scripts via /updateOptions REST requests. The Email Marketing for WordPress and WooCommerce – Retainful plugin insufficiently sanitizes the endpoint's data parameter and escapes its output, allowing stored script content to execute in affected pages. Subscriber-level access is sufficient to inject the content; execution requires a user to access an injected page and occurs in that user's browser.
