The infrastructure team would like to acknowledge the work of security researcher Joël Aviad Ossi from pentest in helping us improve some security weaknesses in our infrastructure. No user data was at risk nor were our downloads vulnerable at any time; this is simply a note of appreciation rather than a disclosure.
Thanks Joël for your assistance. Anyone with security concerns about the project is always welcome to contact the team directly through the email link at https://www.phpmyadmin.net/security/.
