Name of the Vulnerable Software and Affected Versions JSM Screenshot Machine Shortcode plugin for WordPress versions up to, and including, 2.3.0

Description The issue is related to Stored Cross-Site Scripting via the plugin's 'ssm' shortcode due to insufficient input sanitization and output escaping on user-supplied attributes. This allows 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.

Recommendations For versions up to, and including, 2.3.0, update to a version later than 2.3.0 to resolve the issue. As a temporary workaround, consider restricting access to the 'ssm' shortcode for users with contributor-level access and above until a patch is available. Additionally, ensure proper input validation and output escaping for all user-supplied attributes to prevent similar issues in the future.
