Phlox <= 2.17.7 - Authenticated (Contributor+) Stored Cross-Site Scripting via `data-caption` HTML Attribute

Published Jan 6, 2026 · Updated Apr 8, 2026 · Assigned by Wordfence

Description

The Phlox theme for WordPress is vulnerable to Stored Cross-Site Scripting via the `data-caption` HTML attribute in all versions up to, and including, 2.17.7 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.
