It allows external applications and services to interact with your site without needing direct access to the WordPress dashboard.<\/p>\n\n\n\n<p>In earlier versions of WordPress, XML-RPC was disabled by default. However, starting from version 3.5, it has been enabled by default to support features like integration with the WordPress mobile app, allowing it to communicate seamlessly with WordPress installations.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>What xmlrpc.php Does<\/strong><\/h3>\n\n\n\n<p>Originally introduced to support remote publishing, it allows:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Publishing content through mobile applications (such as the WordPress app)&nbsp;<\/li>\n\n\n\n<li>Remote management tools (e.g., Jetpack)<\/li>\n\n\n\n<li>Trackbacks and pingbacks between blogs<\/li>\n\n\n\n<li>Using an outdated version of WordPress (earlier than 4.7)&nbsp;<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>Security Risks of xmlrpc.php<\/strong><\/h3>\n\n\n\n<p>While useful, it\u2019s also a common attack vector:<\/p>\n\n\n\n<h4 class=\"wp-block-heading\"><strong>1. Brute Force Attacks<\/strong><\/h4>\n\n\n\n<p>Hackers use xmlrpc.php to bypass security measures. The file enables attackers to try hundreds of password combinations with a single request, making such attempts harder for traditional security tools to detect.&nbsp;<\/p>\n\n\n\n<h4 class=\"wp-block-heading\"><strong>2. DDoS Amplification (Pingback Abuse)<\/strong><\/h4>\n\n\n\n<p>Attackers can exploit the pingback feature to carry out Distributed Denial of Service (DDoS) attacks, effectively using your site as a tool to target and disrupt other websites.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\"><strong>3. Authentication Bypass Attempts<\/strong><\/h4>\n\n\n\n<p>Although less common today, misconfigured setups can still be vulnerable to exploitation.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>Why You Should Disable xmlrpc.php<\/strong><\/h3>\n\n\n\n<p>The primary reason to disable xmlrpc.php on your WordPress site is that it can introduce security risks and is often targeted by attackers.<\/p>\n\n\n\n<p>Since XML-RPC is no longer essential for external communication with WordPress, keeping it enabled offers little benefit. Disabling it is a simple step to strengthen your site\u2019s security.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\">1.<strong>How to Verify if xmlrpc.php Is Enabled on Your Site:<\/strong><\/h4>\n\n\n\n<p>Before disabling xmlrpc.php, it\u2019s important to verify whether it\u2019s already active. In many cases, hosting providers or security plugins may have disabled it for you.&nbsp;<\/p>\n\n\n\n<p><strong>Method: The XML-RPC Validator Tool<\/strong><\/p>\n\n\n\n<p>One of the easiest ways to check is by using a free online validator tool.<\/p>\n\n\n\n<p>Steps:<\/p>\n\n\n\n<ol class=\"wp-block-list\">\n<li>Open the tool<br>Go to: https:\/\/xmlrpc.blog\/&nbsp;<\/li>\n\n\n\n<li>Enter your website URL<br>Type the full address of your WordPress site (for example, http:\/\/biocalm.com.au ).&nbsp;<\/li>\n\n\n\n<li>Run the check<br>Click the \u201cCheck\u201d button to analyze your site.&nbsp;<\/li>\n\n\n\n<li>Review the results\n<ul class=\"wp-block-list\">\n<li>If you see a green success message, it means xmlrpc.php is enabled and accessible.&nbsp;<\/li>\n\n\n\n<li>If you see a red error message, it likely means the file is disabled or blocked (which is generally a good sign for security).<\/li>\n<\/ul>\n<\/li>\n<\/ol>\n\n\n\n<figure class=\"wp-block-image size-large\"><a href=\"https:\/\/www.supportpro.com\/blog\/wp-content\/uploads\/2026\/05\/image-4.png\" data-rel=\"penci-gallery-image-content\" ><img fetchpriority=\"high\" decoding=\"async\" width=\"1024\" height=\"346\" src=\"https:\/\/www.supportpro.com\/blog\/wp-content\/uploads\/2026\/05\/image-4-1024x346.png\" alt=\"\" class=\"wp-image-17103\" srcset=\"https:\/\/www.supportpro.com\/blog\/wp-content\/uploads\/2026\/05\/image-4-1024x346.png 1024w, https:\/\/www.supportpro.com\/blog\/wp-content\/uploads\/2026\/05\/image-4-300x101.png 300w, https:\/\/www.supportpro.com\/blog\/wp-content\/uploads\/2026\/05\/image-4-768x259.png 768w, https:\/\/www.supportpro.com\/blog\/wp-content\/uploads\/2026\/05\/image-4-1170x395.png 1170w, https:\/\/www.supportpro.com\/blog\/wp-content\/uploads\/2026\/05\/image-4-585x198.png 585w, https:\/\/www.supportpro.com\/blog\/wp-content\/uploads\/2026\/05\/image-4.png 1537w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" \/><\/a><\/figure>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>How to Disable xmlrpc.php<\/strong><\/h3>\n\n\n\n<h4 class=\"wp-block-heading\"><strong>Method 1: Disable via Plugin (Easiest)<\/strong><\/h4>\n\n\n\n<p>Disabling XML-RPC on your WordPress site is easy with a plugin.
