Detailsinfo A vulnerability was found in webmindpt WM JqMath Plugin up to 1.3 on WordPress. It has been classified as problematic. Affected is the function generate_jqMathFormula of the component Shortcode Handler. The manipulation of the argument style with an unknown input leads to a cross site scripting vulnerability. CWE is classifying the issue as CWE-79. The product does not neutralize or incorrectly neutralizes user-controllable input before it is placed in output that is used as a web page that is served to other users. This is going to have an impact on integrity. CVE summarizes: The WM JqMath plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'style' shortcode attribute of the [jqmath] shortcode in all versions up to and including 1.3. This is due to insufficient input sanitization and output escaping on user-supplied shortcode attributes. The generate_jqMathFormula() function directly concatenates the 'style' attribute value into an HTML style attribute without applying esc_attr() or any other 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.
