WordPress 6.3.2 Security Release – What You Need to Know
WordPress Core 6.3.2 was released today, on October 12, 2023. It includes a number of security fixes and additional hardening against commonly exploited vulnerabilities. While all of the vulnerabilities are of Medium severity, several of them are impactful enough to potentially allow site takeover, and thus the 6.3.2 update has the most significant security fixes we’ve seen in a while.
Many of these patches have been backported to every version of WordPress since 4.1, with just a few being backported to the major version in which the functionality was released. WordPress has supported automatic core updates for security releases since WordPress 3.7, and the vast majority of WordPress sites should receive a patch for their major version of WordPress automatically over the next 24 hours. We recommend verifying that your site has been automatically updated to one of the patched versions. Patched versions are available for every major version of WordPress since 4.1, so you can update without risking compatibility issues.
The Wordfence Threat Intelligence Team released two new firewall rules today to protect Wordfence Premium, Wordfence Care, and Wordfence Response customers against the most impactful vulnerabilities patched, and these rules will be available to free Wordfence users in 30 days, on November 11th, 2023.
If your site has not been updated automatically we strongly recommend updating manually as soon as possible, as one of the vulnerabilities patched in this release can be used by an attacker with a low-privileged contributor-level account to take over a site.
Technical Analysis and Overview
As with every WordPress core release containing security fixes, the Wordfence Threat Intelligence team analyzed the code changes in detail to evaluate the impact of these vulnerabilities on our customers, and to ensure our customers remain protected.
