Back in 2008, Google began testing warnings in Webmaster Tools for sites running an old, vulnerable WordPress version. Today the advice is the same, but the tools are better: WordPress can update itself, and Google Search Console alerts you if your site is hacked. Here&#8217;s why you should <strong>update old WordPress versions<\/strong>, what Google does now, and how to keep your site current in 2026.<\/p>\n<p><img decoding=\"async\" class=\"aligncenter size-full wp-image-67780\" src=\"https:\/\/www.quickonlinetips.com\/archives\/wp-content\/uploads\/update-old-wordpress-versions-2026.webp\" alt=\"Update old WordPress versions: metal gears on a blue background\" width=\"1200\" height=\"630\" srcset=\"https:\/\/www.quickonlinetips.com\/archives\/wp-content\/uploads\/update-old-wordpress-versions-2026.webp 1200w, https:\/\/www.quickonlinetips.com\/archives\/wp-content\/uploads\/update-old-wordpress-versions-2026-300x158.webp 300w, https:\/\/www.quickonlinetips.com\/archives\/wp-content\/uploads\/update-old-wordpress-versions-2026-1024x538.webp 1024w, https:\/\/www.quickonlinetips.com\/archives\/wp-content\/uploads\/update-old-wordpress-versions-2026-150x79.webp 150w, https:\/\/www.quickonlinetips.com\/archives\/wp-content\/uploads\/update-old-wordpress-versions-2026-768x403.webp 768w\" sizes=\"(max-width: 1200px) 100vw, 1200px\" \/><\/p>\n<p><strong>Quick answer:<\/strong> Old WordPress versions, plugins and themes contain known security holes that bots scan for automatically. Keep WordPress core, plugins, themes and PHP up to date, turn on automatic updates, back up before major upgrades, and verify your site in Google Search Console so you&#8217;re alerted to hacked content or malware. Google no longer emails about specific WordPress versions, but it does flag sites that have already been compromised.<\/p>\n<div id=\"ez-toc-container\" class=\"ez-toc-v2_0_89 counter-hierarchy ez-toc-counter ez-toc-custom ez-toc-container-direction\">\n<p class=\"ez-toc-title\" style=\"cursor:inherit\">Table of Contents<\/p>\n<label for=\"ez-toc-cssicon-toggle-item-6af168b8e10ca\" class=\"ez-toc-cssicon-toggle-label\"><span class=\"ez-toc-cssicon\"><span class=\"eztoc-hide\" style=\"display:none;\">Toggle<\/span><span class=\"ez-toc-icon-toggle-span\"><svg style=\"fill: #1a202c;color:#1a202c\" xmlns=\"http:\/\/www.w3.org\/2000\/svg\" class=\"list-377408\" width=\"20px\" height=\"20px\" viewBox=\"0 0 24 24\" fill=\"none\"><path d=\"M6 6H4v2h2V6zm14 0H8v2h12V6zM4 11h2v2H4v-2zm16 0H8v2h12v-2zM4 16h2v2H4v-2zm16 0H8v2h12v-2z\" fill=\"currentColor\"><\/path><\/svg><svg style=\"fill: #1a202c;color:#1a202c\" class=\"arrow-unsorted-368013\" xmlns=\"http:\/\/www.w3.org\/2000\/svg\" width=\"10px\" height=\"10px\" viewBox=\"0 0 24 24\" version=\"1.2\" baseProfile=\"tiny\"><path d=\"M18.2 9.3l-6.2-6.3-6.2 6.3c-.2.2-.3.4-.3.7s.1.5.3.7c.2.2.4.3.7.3h11c.3 0 .5-.1.7-.3.2-.2.3-.5.3-.7s-.1-.5-.3-.7zM5.8 14.7l6.2 6.3 6.2-6.3c.2-.2.3-.5.3-.7s-.1-.5-.3-.7c-.2-.2-.4-.3-.7-.3h-11c-.3 0-.5.1-.7.3-.2.2-.3.5-.3.7s.1.5.3.7z\"\/><\/svg><\/span><\/span><\/label><input type=\"checkbox\"  id=\"ez-toc-cssicon-toggle-item-6af168b8e10ca\" checked aria-label=\"Toggle\" \/><nav><ul class='ez-toc-list ez-toc-list-level-1 ' ><li class='ez-toc-page-1 ez-toc-heading-level-2'><a class=\"ez-toc-link ez-toc-heading-1\" href=\"https:\/\/www.quickonlinetips.com\/archives\/2008\/10\/google-warns-old-wordpress-versions\/#What_Google_did_in_2008\" >What Google did in 2008<\/a><\/li><li class='ez-toc-page-1 ez-toc-heading-level-2'><a class=\"ez-toc-link ez-toc-heading-2\" href=\"https:\/\/www.quickonlinetips.com\/archives\/2008\/10\/google-warns-old-wordpress-versions\/#What_Google_does_today\" >What Google does today<\/a><\/li><li class='ez-toc-page-1 ez-toc-heading-level-2'><a class=\"ez-toc-link ez-toc-heading-3\" href=\"https:\/\/www.quickonlinetips.com\/archives\/2008\/10\/google-warns-old-wordpress-versions\/#Why_old_WordPress_versions_are_risky\" >Why old WordPress versions are risky<\/a><\/li><li class='ez-toc-page-1 ez-toc-heading-level-2'><a class=\"ez-toc-link ez-toc-heading-4\" href=\"https:\/\/www.quickonlinetips.com\/archives\/2008\/10\/google-warns-old-wordpress-versions\/#How_to_keep_WordPress_updated_in_2026\" >How to keep WordPress updated in 2026<\/a><\/li><li class='ez-toc-page-1 ez-toc-heading-level-2'><a class=\"ez-toc-link ez-toc-heading-5\" href=\"https:\/\/www.quickonlinetips.com\/archives\/2008\/10\/google-warns-old-wordpress-versions\/#Should_you_hide_your_WordPress_version\" >Should you hide your WordPress version?<\/a><\/li><li class='ez-toc-page-1 ez-toc-heading-level-2'><a class=\"ez-toc-link ez-toc-heading-6\" href=\"https:\/\/www.quickonlinetips.com\/archives\/2008\/10\/google-warns-old-wordpress-versions\/#FAQ\" >FAQ<\/a><ul class='ez-toc-list-level-3' ><li class='ez-toc-heading-level-3'><a class=\"ez-toc-link ez-toc-heading-7\" href=\"https:\/\/www.quickonlinetips.com\/archives\/2008\/10\/google-warns-old-wordpress-versions\/#Does_WordPress_update_automatically\" >Does WordPress update automatically?<\/a><\/li><li class='ez-toc-page-1 ez-toc-heading-level-3'><a class=\"ez-toc-link ez-toc-heading-8\" href=\"https:\/\/www.quickonlinetips.com\/archives\/2008\/10\/google-warns-old-wordpress-versions\/#Is_it_safe_to_update_WordPress\" >Is it safe to update WordPress?<\/a><\/li><li class='ez-toc-page-1 ez-toc-heading-level-3'><a class=\"ez-toc-link ez-toc-heading-9\" href=\"https:\/\/www.quickonlinetips.com\/archives\/2008\/10\/google-warns-old-wordpress-versions\/#How_do_I_check_my_WordPress_version\" >How do I check my WordPress version?<\/a><\/li><li class='ez-toc-page-1 ez-toc-heading-level-3'><a class=\"ez-toc-link ez-toc-heading-10\" href=\"https:\/\/www.quickonlinetips.com\/archives\/2008\/10\/google-warns-old-wordpress-versions\/#Will_Google_penalize_my_site_for_running_old_WordPress\" >Will Google penalize my site for running old WordPress?<\/a><\/li><\/ul><\/li><\/ul><\/nav><\/div>\n<h2><span class=\"ez-toc-section\" id=\"What_Google_did_in_2008\"><\/span>What Google did in 2008<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>In October 2008 Google ran a limited test in Webmaster Tools (now Search Console), sending Message Center warnings to webmasters running WordPress 2.1.1. That release was notorious because an attacker had broken into a wordpress.org server and modified the 2.1.1 download files. Google said it might expand the warnings to other web software if the test went well.<\/p>\n<p>This was the sample message affected site owners saw:<\/p>\n<p><img decoding=\"async\" class=\"aligncenter size-full wp-image-4487\" src=\"https:\/\/www.quickonlinetips.com\/archives\/wp-content\/uploads\/message-example.png\" alt=\"Google Webmaster Tools warning about an outdated, hackable WordPress version\" width=\"385\" height=\"111\" \/><\/p>\n<p>At the time we thought it was a smart move. We also noted that a blog that hadn&#8217;t been upgraded in over a year was probably abandoned, and abandoned sites are exactly the ones attackers love.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"What_Google_does_today\"><\/span>What Google does today<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>Google doesn&#8217;t send version-specific WordPress warnings any more. Instead, the <a href=\"https:\/\/support.google.com\/webmasters\/answer\/9044101\" target=\"_blank\" rel=\"noopener\">Security issues report in Google Search Console<\/a> tells you if Google detects hacked content, malware or deceptive pages on your site. Visitors may see a browser warning, and your rankings can suffer until you clean up and request a review. Updating is how you avoid getting there.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"Why_old_WordPress_versions_are_risky\"><\/span>Why old WordPress versions are risky<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<ul>\n<li><strong>Known vulnerabilities:<\/strong> once a security fix is released, the flaw it patches becomes public, and automated bots start probing every site that hasn&#8217;t updated.<\/li>\n<li><strong>Plugins and themes:<\/strong> most WordPress hacks come through outdated plugins and themes, not core.<\/li>\n<li><strong>Old PHP:<\/strong> unsupported PHP versions no longer get security fixes and slow your site down.<\/li>\n<li><strong>Abandoned add-ons:<\/strong> plugins that haven&#8217;t been updated in years may never get a fix.<\/li>\n<\/ul>\n<h2><span class=\"ez-toc-section\" id=\"How_to_keep_WordPress_updated_in_2026\"><\/span>How to keep WordPress updated in 2026<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<ol>\n<li><strong>Back up first.<\/strong> Use your host&#8217;s backups or a backup plugin before major updates.<\/li>\n<li><strong>Update core.<\/strong> Go to Dashboard &gt; Updates and install the latest version.
