What to do
- There is no fixed version yet. If you can live without Social Share Buttons for now, deactivate it and delete it until the developer ships a fix.
- If you must keep it, limit who can log in (remove unused accounts, especially low-level ones) and put a web application firewall in front of the site.
- Watch for an update: get an email when this page changes.
- If you ran a vulnerable version and something looks off (spam pages, strange admins, redirects), run the free scan, or have us clean it: Emergency Cleanup, $499.
With WP-CLI: wp plugin get share-button --field=version shows what you run; wp plugin update share-button updates it.

Details from the advisory
The Social Share Buttons plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'form (containing share_url)' parameter in all versions up to, and including, 1.30 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with subscriber-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. Exploitation requires that the 7-day review-nag timer has elapsed since the attacker's first wp-admin visit, as the nonce needed to reach the save-network handler is only rendered in the DOM once that timer has passed.
