Pimcore ENV Variables and Cookie Informations are exposed in http_error_log

  • Disclosed: 15.01.2026
  • Updated: 11.10.2026 10:22

Summary

The http_error_log file stores the $_COOKIE and $_SERVER variables, which means sensitive information such as database passwords, cookie session data, and other details can be accessed or recovered through the Pimcore backend.

Details

It’s better to remove both lines, as this information makes little sense in this context anyway.
