3 security issues affects WordPress versions between 5.4 and 5.8. If you haven’t yet updated to 5.8, all WordPress versions since 5.4 have also been updated to fix the following security issues:
- Props @mdawaffe, member of the WordPress Security Team for their work fixing a data exposure vulnerability within the REST API.
- Props to Michał Bentkowski of Securitum for reporting a XSS vulnerability in the block editor.
- The Lodash library has been updated to version 4.17.21 in each branch to incorporate upstream security fixes.
In addition to these fixes, the security team would like to thank Steve Henty and Evan Ricafort for reporting a XSS vulnerability discovered during the 5.8 release’s beta period. This was previously fixed in the final release of WordPress 5.8.
Thank you to all of the reporters for privately disclosing the vulnerabilities. This gave the security team time to fix the vulnerabilities before WordPress sites could be attacked.
