This week, 79 vulnerabilities may affect over 6.6 million WordPress sites. There are 55 plugin vulnerabilities and 5 themes with security patches available, so run those updates if you use these plugins! Additionally, there are 19 plugin vulnerabilities with no patch available yet. At least three of these have been closed and dropped from the wordpress.org plugin directory so far. If you are using any unpatched plugins or themes, check their vendors’ intentions and progress on a security release. If no patch is forthcoming or the vulnerable plugin or theme has been closed, you should consider deactivation and removal in favor of alternative solutions.

For reference, these reports are published every Wednesday and include all active vulnerabilities tracked by Patchstack as of Monday since the previous report. This leaves a 48-hour window for the newest emerging vulnerabilities to be patched before full public disclosure. iThemes Security Pro users have access to vulnerability alerts emerging within this window.

WordPress vulnerability report
No new WordPress core vulnerabilities were disclosed this week.

WordPress core is very secure when it’s properly configured and maintained. Vulnerable plugins that have not been updated by site owners are the most common vector for attacks on WordPress websites. Our weekly WordPress Vulnerability Report, powered by Patchstack, covers new WordPress plugin, theme, and core vulnerabilities that have emerged since last week’s report. Our goal is to spread awareness of emerging security threats and help you decide what to do if you are using vulnerable software on your website. For a deeper analysis of recent trends in WordPress vulnerabilities and threat vectors, see our 2022 Annual Vulnerability Report.

WordPress Core News

WordPress 6.2 is the first major release of 2023, with over 900 enhancements and fixes. You’ll notice a reimagined Site Editor, blocks get even better, and new tools and improvements in WordPress 6.2. As always, with a major release like this, ensure your site is backed up with BackupBuddy before updating.

If your WordPress sites have enabled automatic background updates, they should have upgraded to 6.2 automatically. You can download WordPress 6.2 from WordPress.org, or visit your WordPress Dashboard, click “Updates,” and then click the “Update Now” button, which will appear when any core updates are available. For more information, check out the version 6.2 HelpHub documentation page.
