Summary

The Social Share Buttons & Analytics Plugin – GetSocial.io plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'response' parameter in all versions up to and including 4.5 due to insufficient input sanitization and output escaping. Authenticated attackers with subscriber-level access and above can inject arbitrary web scripts into pages that execute in an administrator's browser when the GetSocial settings page is visited.

Risk Assessment

The injected malicious script may execute in the administrator's browser, potentially leading to session hijacking, data theft, or modification of site configuration.

Recommendation

Update the GetSocial.io plugin to a version later than 4.5 or remove it if unused; additionally review the gs-alert-msg, gs-alert-utm, and gs-alert-cta options for injected scripts.
