What are the Upcoming WordPress Security Updates in 2025?

According to Patchstack’s 2025 mid-year vulnerability report, 6,700 new vulnerabilities were identified in the WordPress ecosystem in just six months, with 41% exploitable in real-world scenarios. WordPress 6.9, releasing December 2nd, 2025, introduces enhanced WordPress security updates, hardening, and improved HTML API protections to address these growing threats.

WP Enchant, serving WordPress agencies and site owners, has analyzed the upcoming security landscape to help businesses prepare for these critical changes. Understanding these updates becomes essential as WordPress sites face an average of 30,000 hacking attempts daily.

This comprehensive guide explores the key security changes arriving in 2025, helping you identify which updates affect your site and how to implement them effectively.

Quick Answer: What WordPress Security Updates Are Coming to WordPress in 2025?

WordPress 6.9 introduces enhanced HTML API security hardening, improved plugin screening processes, and stricter authentication requirements, with release scheduled for December 2nd, 2025. Additional changes include expanded application password controls and automated security update improvements.

The most significant updates focus on proactive threat prevention rather than reactive patching, marking a fundamental shift in WordPress security strategy.

WordPress 6.9 Security Enhancements Overview

Enhanced HTML API Security Hardening

WordPress 6.9’s updated HTML API increases the platform’s reliability and improves security hardening while reducing maintenance burden on the core project.

The HTML API changes represent one of the most significant under-the-hood security improvements in recent WordPress history. These updates strengthen how WordPress processes and sanitizes HTML content, providing better protection against XSS attacks and malicious code injection.

WP Enchant’s security analysis shows these improvements particularly benefit sites handling user-generated content or custom HTML blocks. The enhanced parsing logic better identifies and neutralizes potentially dangerous HTML structures before they can execute malicious code.

Technical Implementation Details

The new HTML API introduces:

• Stricter validation rules for HTML attributes and values
• Enhanced sanitization of dynamic content blocks
• Improved handling of nested HTML structures
• Better protection against DOM-based XSS vulnerabilities

These WordPress security changes automatically activate with WordPress 6.9 installation, requiring no manual configuration from site administrators.

Plugin Security Screening Revolution

WordPress.org now implements automated screening for plugin updates, checking security, compatibility, and compliance before public release.

This represents the most comprehensive plugin security initiative WordPress has ever launched. The screening process analyzes plugin code for known vulnerability patterns, compatibility issues with current WordPress versions, and adherence to coding standards.

For site owners using WP Enchant’s maintenance services, this change means significantly reduced risk from plugin-related security vulnerabilities. The automated screening catches potential issues before they reach production environments.

Impact on Plugin Ecosystem

The new screening process affects:

• Plugin developers: Must ensure code meets security standards before approval
• Site owners: Receive more secure plugin updates with reduced vulnerability risk
• Security professionals: Can rely on enhanced baseline security for WordPress plugins
• Hosting providers: Experience fewer security incidents from plugin vulnerabilities

Application Password Security Controls

WordPress continues expanding its application password functionality with enhanced security controls and better integration with two-factor authentication systems.

Application passwords provide secure API access without exposing primary account credentials. The 2025 updates introduce granular permission controls, allowing administrators to restrict application password capabilities based on user roles and specific API endpoints.

WP Enchant recommends migrating from traditional API authentication methods to application passwords for improved security. The new controls allow precise management of automated processes while maintaining strong security boundaries.

Setting Up Enhanced Application Passwords

1. Navigate to User Profile: Access Users > Your Profile in WordPress admin
2. Locate Application Passwords section: Found under security settings
3. Generate specific passwords: Create unique passwords for different applications
4. Configure permissions: Set appropriate access levels for each application password
5. Monitor usage: Review application password activity in security logs

Automated Security Update Improvements

WordPress 6.8.1 introduced new defense systems against cyberattacks, with automatic minor security updates enabled by default and enhanced Site Health diagnostics.

The improved automatic update system provides faster deployment of security patches while maintaining site stability. WordPress now categorizes WordPress security updates by severity level, with critical patches deploying within hours of release.

These enhancements work seamlessly with WP Enchant’s maintenance plans, ensuring sites receive security updates promptly while maintaining scheduled maintenance protocols.

Update Categories and Timing

• Critical security patches: Deploy automatically within 2-4 hours
• Standard security updates: Roll out over 24-48 hours
• Plug-security fixes: Update based on plugin screening results
• Theme security patches: Implement the following compatibility verification

Enhanced Site Health Diagnostics

WordPress Site Health receives expanded diagnostic capabilities, providing better visibility into security configuration and potential vulnerabilities.

The enhanced diagnostics identify security misconfigurations, outdated components, and potential attack vectors before they become active threats. Site Health now includes specific recommendations for implementing WordPress security best practices.

WP Enchant’s security audits benefit from these expanded diagnostics, providing more comprehensive security assessments and targeted improvement recommendations.

Two-Factor Authentication Expansion

WordPress.org mandates two-factor authentication for all contributors with publishing capabilities, signaling broader 2FA adoption across the ecosystem.

This requirement demonstrates WordPress’s commitment to enhanced authentication security. The mandate affects plugin developers, theme creators, and core contributors, establishing 2FA as the new standard for WordPress ecosystem participation.

The expansion includes:

• Simplified 2FA setup processes for various user roles
• Better integration with popular authenticator applications
• Enhanced backup code management
• Improved recovery procedures for lost authentication devices

Vulnerability Response Improvements

Wordfence reports 1,857 total vulnerabilities in Q3 2025, representing a 32.4% decrease from the previous quarter, indicating improved proactive security measures.

The declining vulnerability numbers reflect the effectiveness of WordPress’s enhanced security initiatives. Improved plugin screening, better code review processes, and proactive security research contribute to this positive trend.

However, with 108 new vulnerabilities still disclosed in November 2025 alone, maintaining current security practices remains critical for all WordPress sites.

Security Threat Landscape 2025

WordPress security professionals have identified four key threat trends emerging in 2025:

AI-Generated Attack Vectors

Malicious actors increasingly use AI to generate polymorphic malware that changes signatures to evade traditional security detection. This trend requires enhanced behavioral analysis and pattern recognition in security tools.

Weaponized Vulnerability Scripts

Automated scripts now weaponize vulnerabilities before security patches become available, reducing the window between disclosure and exploitation. This emphasizes the importance of proactive security hardening.

Supply Chain Attacks

Attackers target plugin and theme developers to inject malicious code into legitimate extensions. WordPress’s enhanced plugin screening directly addresses this growing threat vector.

Zero-Day Exploitation

Sophisticated attackers focus on zero-day vulnerabilities in popular plugins and themes. The improved vulnerability response system helps minimize exposure windows.
