The ER Swiffy Insert plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the [swiffy] shortcode in all versions up to and including 1.0.0. This is due to insufficient input sanitization and output escaping on user-supplied shortcode attributes ('n', 'w', 'h'). These attributes are extracted using extract() and directly interpolated into the HTML output without any escaping such as esc_attr(). 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.
AnalysisAI
Stored cross-site scripting in the ER Swiffy Insert WordPress plugin through version 1.0.0 allows authenticated users with Contributor access or higher to inject arbitrary JavaScript via unsanitized shortcode attributes that are directly interpolated into page output. The vulnerability affects all versions of the plugin and requires only contributor-level privileges to exploit, making it a persistence and privilege-escalation vector on WordPress sites with multiple user accounts.
