Details

As written in the advisory (Markdown source, shown as plain text).

### 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. https://github.com/pimcore/pimcore/blob/12.x/bundles/SeoBundle/src/EventListener/ResponseExceptionListener.php#L92 https://github.com/pimcore/pimcore/blob/12.x/bundles/SeoBundle/src/EventListener/ResponseExceptionListener.php#L93 ### PoC In the Pimcore backend, navigate to "Search Engine Optimization" and click on "HTTP Errors." Double-click on an entry to view its details. Here, you may find sensitive data exposed. ### Impact Pimcore backend users can access sensitive environment variables, potentially exposing critical information.
