Tips To Solve Most Common WordPress Vulnerabilities 2024

WordPress powers a substantial share of the web, which makes it a perennial target for attackers. The WPScan 2024 Website Threat Report sets out where those attacks tend to concentrate, and the picture is consistent: the platform’s greatest strengths—its extensibility and its vast ecosystem of third-party code—are also its most reliable points of failure.

The Three Main Sources of Risk

Plugins

Plugins account for the overwhelming majority of WordPress security incidents. According to the report, more than 90% of threats traced to WordPress sites originate in plugin code. The usual suspects are plugins that have been abandoned by their developers, or those written without proper attention to input handling, leaving openings for cross-site scripting (XSS) and SQL injection.

Reducing that risk is largely a matter of discipline:

• Apply plugin updates as soon as they are released.
• Delete anything you no longer use rather than leaving it deactivated.
• Favour plugins with active maintainers and a track record of timely patches.
• Where updates are frequent or the stack is complex, hand the work to a developer who can test changes before they go live.

Themes

Themes present a similar problem. Outdated themes, or those built without security in mind, give attackers a straightforward way in. The same rules apply: keep your theme current, source it from a developer with a solid reputation, and treat any custom build as a security project in its own right rather than a purely visual one.

WordPress Core

Core vulnerabilities are rarer than plugin or theme issues, and the WordPress project is generally quick to patch them. The risk lies in delay—an unpatched installation is an exposed one. Keep core on the latest release, allow automatic updates for minor versions, and coordinate major updates with a developer so they don’t collide with your plugins or theme.

Wider Security Practices

Beyond patching, a handful of measures close off the most common routes of attack.

Strong credentials and two-factor authentication. Weak passwords remain an easy way in. Use long, unique passwords for every account tied to the site, and enable two-factor authentication wherever it is offered.

A dedicated security plugin. Tools such as Wordfence and Sucuri monitor for malware and suspicious activity, providing real-time protection and flagging vulnerabilities before they are exploited.

Regular backups. Backups are what let you recover from an attack or a failure. Keep copies both locally and in the cloud so a restore is quick when it is needed.

Login attempt limits. Brute-force attacks rely on unlimited guesses. Capping failed login attempts—manually or through a security plugin that locks out an IP after a set number of failures—removes that advantage.

The Case for Ongoing Maintenance

Security is not a one-off task. Vulnerabilities emerge continuously, and staying ahead of them takes time and technical judgement that many site owners simply do not have in-house. A developer who handles updates, monitors for threats and tests changes before deployment turns security from a periodic scramble into routine maintenance—keeping the site both protected and performing as it should.

The pattern in the 2024 data is clear enough: most compromises trace back to neglected plugins, stale themes and weak configuration. Addressing those three areas, and putting a maintenance routine in place behind them, removes the majority of the risk.
