WordPress Vulnerability Report – May 31, 2023

On May 20, 2023, WordPress 6.2.2 was released to address a regression — a bug introduced in 6.2.1 that broke shortcode functionality — as well as a security issue. Because 6.2.2 is a security release, you should update your sites immediately. All versions since WordPress 5.9 have also been updated. The next major version of WordPress Core, slated for an August release, will be 6.3.

WordPress core has been updated to secure one vulnerability disclosed with its 6.2.2 release. In the plugin and theme ecosystem, 85 total vulnerabilities emerged in public disclosure. They may affect over 12 million WordPress sites. Out of the total number, there are 57 plugin vulnerabilities and 2 theme vulnerabilities that have security patches available.

Additionally, there are 25 plugin vulnerabilities and 1 theme vulnerability with no patch available yet. 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 software has been closed and dropped from the official WordPress theme and plugin repositories, you should consider deactivation and removal in favor of alternative solutions.

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.
