Description The Flask Micro code-editor plugin for WordPress is susceptible to Stored Cross-Site Scripting. This is due to insufficient input sanitization and output escaping on user-supplied attributes within the plugin’s codeflask shortcode. Authenticated attackers with contributor-level access or higher can inject arbitrary web scripts into pages. These scripts will execute when a user accesses the injected page.
