Injection Guard

Injection Guard is a WordPress plugin designed to block malicious query string attacks and suspicious URL parameters. It logs all incoming attempts, blocks harmful parameters, and adds extra security intelligence to your WordPress admin—like user session tracking and capability audit.

The plugin uses the ig_ prefix for database keys and functions, follows WordPress coding standards, and supports multiple languages. It’s compatible with pretty permalinks and helps in securing your site from automated bots and manual attacks.

How it works: Injection Guard learns which query-string parameters your visitors use (only the names, never the values). You mark each one as good or bad from the Log tab; bad parameters are blocked on that URL from then on. New in 1.4: an optional attack-signature scan, a global blacklist, safe-parameter patterns, a blocked-requests list with CSV export, and a dashboard that shows what is happening at a glance.

Pro version

Automatic IP ban for repeat offenders, email alerts, a new-administrator watch (also catches accounts created straight in the database), an extended signature set with scanner user-agent blocking, an IP allowlist and a capability-audit CSV export.
