Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-200: Exposure of Sensitive Information to an Unauthorized Actor, where the product exposes sensitive information to an actor that is not explicitly authorized to have access to that information. In Ibexa/post install, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

The default configuration for platform.sh (.platform.app.yaml) allows access to uploaded files if you know or can guess their location, regardless of whether roles grant content read access to the content containing those files. If you're using Legacy Bridge, the default configuration also allows access to certain legacy files that should not be readable, including the legacy var directory and extension directories.
