What to do now

Replace Social Web Suite. A closed plugin gets no updates through WordPress, so this hole stays open.
Deactivate and delete it once you have a replacement (Plugins → Deactivate → Delete). Deactivating alone leaves its files on the server.
Not sure which version you run? Check your version against every known Social Web Suite issue.
If you ran an affected version and something looks off (new admin users, spam pages, redirects), run the free scan below.

The advisory

The Social Web Suite WordPress plugin through 4.1.12 does not require its shared secret to be set before accepting requests authorised by it, and does not sanitise and escape a parameter before using it in an SQL statement, allowing unauthenticated users to perform SQL injection attacks.
