Ayo Shortcodes WordPress Plugin Stored Cross-Site Scripting Vulnerability

A stored cross-site scripting vulnerability has been identified in the Ayo Shortcodes plugin for WordPress, affecting all versions through 0.2. The issue arises in the 'color' parameter of the 'ayo_action' shortcode, where inadequate input sanitization and output escaping allow authenticated attackers with Contributor-level access or higher to inject arbitrary scripts. These scripts are executed when a user accesses the affected page.

Impact

Exploitation of this vulnerability allows for stored cross-site scripting, where injected scripts are executed in the context of the user viewing the page.

Reproduction

To reproduce this vulnerability, an authenticated user with Contributor-level access or higher can use the 'ayo_action' shortcode and include a script in the 'color' parameter. Once the shortcode is saved and the page is viewed, the injected script will execute.

Remediation

No known patch is available for this vulnerability. It is recommended to uninstall the affected plugin and find a replacement.
