WordPress has recently released patch 4.8.3 to fix an SQL injection security vulnerability. This vulnerability concerned an exploit in which a line of maliciouscode could create queries with the potential to perform SQL injection-based attacks, potentially allowing attackers to hijack entire websites. Whilst injection can be severe for website owners, particularly with the potential for site hijacks, the attack has been patched. Users will remain vulnerable if they have not updated, however automatic updates are enabled by default so the number of users remaining should be low.
WordPress versions 4.8.2 and below.
