Name of the Vulnerable Software and Affected Versions Include Mastodon Feed plugin for WordPress versions up to, and including, 1.9.5

Description The issue is related to Stored Cross-Site Scripting due to insufficient input sanitization and output escaping on user-supplied attributes in the plugin's 'include-mastodon-feed' shortcode. 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, 1.9.5, update to a version that addresses the insufficient input sanitization and output escaping issue. As a temporary workaround, consider restricting access to the 'include-mastodon-feed' shortcode to prevent authenticated attackers from injecting arbitrary web scripts.
