What it is

⚡ Your backend is spilling secrets! Before versions 12.3.1 and 11.5.14, Pimcore was accidentally logging sensitive $_COOKIE and $_SERVER data, just waiting for the wrong hands to find it. 🚨 Think of it like a restaurant that writes down every customer's order, including their credit card details, and leaves that notepad lying around for anyone to see. In the world of data management, that’s a recipe for disaster! An attacker could potentially access sensitive information like database passwords and session data, putting your entire platform at risk. This means your database could be exposed, and an attacker could waltz in and wreak havoc on your system. Absolutely devastating!

Put simply

Think of it like a restaurant that writes down every customer's order, including their credit card details, and leaves that notepad lying around for anyone to see. In the world of data management, that’s a recipe for disaster! This vulnerability in Pimcore allows sensitive data to be logged in the http_error_log file due to misconfigured error handling, exposing critical information to anyone with backend access.

What to do

An attacker could potentially access sensitive information like database passwords and session data, putting your entire platform at risk. This means your database could be exposed, and an attacker could waltz in and wreak havoc on your system. Absolutely devastating! Update immediately to versions 12.3.1 or 11.5.14 to close this security gap. Review your logging and error-handling configurations to ensure no sensitive data is being captured inappropriately. Don't forget to audit your access controls! You've got this! Take these steps, and you'll be on your way to securing your Pimcore setup in no time! 🛡️
