Late-breaking news on the 5.2.4 short-cycle security release that landed October 14. When we released the news post, I inadvertently missed giving props to Simon Scannell of RIPS Technologies for finding and disclosing an issue where path traversal can lead to remote code execution.
Simon has done a great deal of work on the WordPress project, and failing to mention his contributions is a huge oversight on our end.
Thank you to all of the reporters for privately disclosing vulnerabilities, which gave us time to fix them before WordPress sites could be attacked.
