Two security issues affect WordPress versions between 4.7 and 5.7. If you haven’t yet updated to 5.7, all WordPress versions since 4.7 have also been updated to fix the following security issues:
- thank you SonarSource for reporting an XXE vulnerability within the media library affecting PHP 8
- thanks Mikael Korpela for reporting a data exposure vulnerability within the latest posts block and REST API
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.
