Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
The Shortcodes and extra features for Phlox theme plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the HTML Element in all versions up to, and including, 2.15.7 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with contributor access or higher, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. Requires Elementor and the Phlox theme to be installed.

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

dbcve analysis · high confidence

The Shortcodes and extra features for Phlox theme plugin for WordPress contains a stored XSS vulnerability in its HTML Element feature. Due to insufficient input sanitization and output escaping, authenticated users with contributor-level access or higher can inject arbitrary JavaScript into pages. This malicious script executes whenever other users access those pages, enabling session hijacking, credential theft, or defacement.

MitigationUpdate the plugin to a version beyond 2.15.7 once available. Additionally, audit existing pages using the HTML Element for any injected malicious scripts and remove them, as the vulnerability is stored.
