Name of the Vulnerable Software and Affected Versions Sassy Social Share plugin for WordPress versions up to, and including, 3.3.75

Description The issue is related to Reflected Cross-Site Scripting due to insufficient input sanitization and output escaping. This allows unauthenticated attackers to inject arbitrary web scripts in pages that execute if they can successfully trick a user into performing an action, such as clicking on a link. The heateor mastodon share parameter is specifically vulnerable to this type of attack.

Recommendations For Sassy Social Share plugin for WordPress versions up to, and including, 3.3.75, update to a version higher than 3.3.75 to resolve the issue. As a temporary workaround, consider restricting access to the heateor mastodon share parameter to minimize the risk of exploitation.
