Top 10 Common WordPress Security Concerns and How to Solve Them
Below is a list of the most common WordPress security concerns that seem to have no impact but can be lethal, if ignored. We will also tell you some easy ways to solve them.
1. Outdated Core, Themes, and Plugins
Neglecting updates for the WordPress core, themes, or plugins leaves sites vulnerable. Hackers exploit known WordPress security vulnerabilities in outdated components, leading to data breaches and compromised performance.
Regular updates are a crucial part of the WordPress security checklist. They often include essential security patches, ensuring the website stays resilient against evolving threats.

Why It Matters:
- Puts site data at risk of unauthorized access.
- Increases susceptibility to malware and ransomware.
- Compromises WordPress security audit results.
- Lowers SEO ranking due to security risks.
- Weakens client confidence in site security.
Solution:
- Enable automatic updates for core WordPress software and plugins to ensure security patches are applied.
- Use a staging tool to test updates in a non-live environment before going live, preventing any compatibility issues.
- Run WordPress security scans regularly to verify that the site remains secure post-update.
2. Weak Passwords and Login Security
Weak passwords and the absence of two-factor authentication (2FA) make sites vulnerable to brute-force attacks. Attackers use automated tools to guess login credentials, often succeeding when passwords are easily guessed.
Strong login protocols are essential for WordPress security best practices, safeguarding both site access and sensitive data.
Why It Matters:
- Increases vulnerability to brute-force attacks.
- Compromises admin control of the site.
- Breaches client data privacy and trust.
- Exposes admin accounts to hijacking.
- Violates WordPress security audit standards.
Solution:
- Enforce strong passwords and enable 2FA for enhanced security.
- Utilize InstaWP’s CLI command feature to automate password strength checks and enforce complex passwords.
- Install a WordPress security plugin to limit login attempts and protect the login page, reducing brute-force attack success rates.
3. Unsecured File Permissions
Insecure file permissions allow unauthorized users to access, modify, or delete files. Common issues arise when permissions are set too loosely, giving attackers a direct path to sensitive directories.
Correct permissions are vital to WordPress security best practices, reducing the risk of accidental or malicious changes.
Why It Matters:
- Exposes critical configuration files to attackers.
- Allows unauthorized file modification or deletion.
- Increases risk of malware injection.
- Compromises overall WordPress security checklist results.
- Undermines server security integrity.
Solution:
- Set file permissions correctly (typically folders at 755, files at 644) to restrict unauthorized access.
- Use WordPress CLI to remotely audit permissions across multiple sites to ensure consistency and security.
- Regularly review permissions, particularly for sensitive files such as wp-config.php.
4. Lack of SSL Encryption
SSL encryption protects data transferred between the server and the user, preventing interception by hackers. Without SSL, websites are vulnerable to man-in-the-middle attacks, which can compromise sensitive information.
SSL is a foundational part of WordPress security best practices and is critical for user trust and data protection.
Why It Matters:
- Secures data transmission against eavesdropping.
- Builds user trust, especially for e-commerce sites.
- Improves SEO by prioritizing HTTPS-secured sites.
- Reduces the risk of data interception by hackers.
- Essential for WordPress security services compliance.
Solution:
- Obtain and correctly configure SSL certificates to secure website data.
- Deploy SSL in staging and live environments using InstaWP’s deployment feature, ensuring consistent SSL coverage.
- Regularly test SSL validity to avoid interruptions in encrypted sessions.
5. Malware and Malicious Code Injections
Malware can infiltrate a site through unvetted plugins, themes, or third-party links. Once inside, malicious code can compromise operations, steal data, and lead to blacklisting by search engines.
Frequent WordPress security scans are crucial to detect and remove malware promptly.
Why It Matters:
- Puts site visitors at risk of malware infection.
- This leads to site blacklisting by search engines.
- Degrades the site’s reputation and credibility.
- Compromises user privacy and data security.
- Disrupts normal site operations.
Solution:
- Perform WordPress security scans regularly using top WordPress security plugins to detect malware early.
- Isolate and test plugins in a staging environment to prevent malicious code from reaching live sites.
- Limit plugin installations to only trusted sources to minimize exposure to malware.
6. SQL Injection Attacks
SQL injections exploit vulnerable input fields, allowing attackers to access or modify database content. This threat can result in unauthorized access to sensitive information like usernames and passwords. Preventing SQL injections is essential for WordPress security.

Why It Matters:
- Puts sensitive user data at risk.
- Allows unauthorized database manipulation.
- Compromises site stability and functionality.
- Undermines the WordPress security audit process.
- Risks exposing client information.
Solution:
- Implement input validation and sanitize all user inputs to mitigate SQL injection risks.
- Use parameterized queries or prepared statements to secure database interactions.
- Use InstaWP’s staging environment to test database-driven features for security.
7. Unmanaged User Roles and Permissions
Improperly managed user roles and permissions can expose sensitive site areas to unauthorized users. Granting excessive privileges is a common oversight that compromises WordPress security best practices.
Why It Matters:
- Allows unauthorized access to site management.
- Risks accidental or malicious data changes.
- Reduces site control and oversight.
- Affects overall WordPress security audit outcomes.
- Increases chances of accidental site errors.
Solution:
- Regularly audit user roles and permissions to ensure only necessary access is granted.
- Restrict admin privileges to only essential personnel to avoid accidental damage.
8. Vulnerable WordPress Themes and Plugins
Themes and plugins are common targets for hackers, who exploit vulnerabilities in unmaintained or poorly-coded add-ons. Using reputable plugins is part of every WordPress security checklist and helps reduce risk exposure.

Why It Matters:
- Makes sites susceptible to malicious attacks.
- Risks unauthorized data extraction.
- Causes unexpected functionality issues.
- Compromises user and client trust.
- Requires costly repairs or site downtime.
Solution:
- Select only well-maintained plugins and themes from reputable sources, regularly updating them.
- Test all new plugins in the staging environment to check for compatibility and security.
- Remove any unused or outdated plugins to reduce the attack surface.
9. Cross-Site Scripting (XSS) Attacks
XSS attacks inject malicious scripts into a website via user inputs, allowing hackers to hijack user sessions or steal sensitive information. Addressing XSS is essential for maintaining WordPress content security policy standards.
Why It Matters:
- Risks exposing user data to hackers.
- Erodes client trust and user confidence.
- Increases vulnerability to data breaches.
- Can lead to site defacement.
- Impacts WordPress security audit scores.
Solution:
- Use input validation and data sanitization to prevent XSS vulnerabilities.
- Test form inputs in InstaWP’s staging environment to verify they’re secure.
- Implement a Content Security Policy (CSP) header to restrict unsafe scripts.
10. Unprotected WP-Admin Area
The wp-admin area is the control hub for WordPress sites, and an unprotected wp-admin exposes the site to unauthorized access. Strengthening this area is critical for WordPress security and overall site integrity.
Why It Matters:
- Allows hackers direct access to backend controls.
- Poses a risk of site defacement.
- Compromises client data and sensitive settings.
- Affects overall WordPress security audit results.
- Diminishes the trustworthiness of the site.
Solution:
- Use IP whitelisting to restrict access to wp-admin to trusted addresses only.
- Require two-factor authentication (2FA) for wp-admin users for extra protection.
Conclusion
Keeping WordPress secure is critical for site owners, agencies, and developers alike. By proactively addressing WordPress security vulnerabilities and following a rigorous WordPress security checklist, you can ensure your sites remain resilient, safe, and trusted by users—empowering your business to grow with confidence.
