WordPress 5.9.2 Security and Maintenance Release

WordPress 5.9.2 is now available!

This security and maintenance release features 1 bug fix in addition to 3 security fixes. Because this is a security release, it is recommended that you update your sites immediately. All versions since WordPress 3.7 have also been updated.

WordPress 5.9.2 is a security and maintenance release. The next major release will be version 6.0.

You can download WordPress 5.9.2 from WordPress.org, or visit your Dashboard → Updates and click “Update Now”.

If you have sites that support automatic background updates, they’ve already started the update process.

The security team would like to thank the following people for responsively reporting vulnerabilities, allowing them to be fixed in this release:

• Melar Dev, for finding a Prototype Pollution Vulnerability in a jQuery dependency
• Ben Bidner of the WordPress security team, for finding a Stored Cross Site Scripting Vulnerability
• Researchers from Johns Hopkins University, for finding a Prototype Pollution Vulnerability in the block editor

For more information, browse the full list of changes on Trac, or check out the version 5.9.2 HelpHub documentation page.

Thanks and props!
