ezsystems/ezpublish-kernel fixed: 7.5.31 
Upgrade ezsystems/ezpublish-kernel to 7.5.31
Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release: 

inspect dependencies for ezsystems/ezpublish-kernel

How to Check if You Are Affected

To determine whether your application is affected by GHSA-946c-f9w6-2c25, inspect your project dependencies for Ezsystems/ezpublish kernel:

inspect dependencies for ezsystems/ezpublish-kernel

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under General Security Weakness. In Ezsystems/ezpublish kernel, 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

### Impact The route used for file downloads allows specifying the name of the downloaded file. This is an unintended side effect of the implementation, and means one could construct download URLs with filenames that have no relation to the actual file, which could lead to misunderstandings and confusion, and possibly other harm. As such it is a low severity vulnerability. It affects all supported versions of Ibexa DXP and eZ Platform, in installations where downloadable files exist. ### Patches The issue is fixed in all supported versions of ezsystems/ezpublish-kernel, see "Patched versions". An advisory is also published for ezsystems/ezplatform-kernel and ibexa/core, please see those repositories. Commit: https://github.com/ezsystems/ezpublish-kernel/commit/142152f9bae4c4835713df0bdfe22bc98d03f9a1 ### Workarounds None, other than blocking all downloads. ### References https://developers.ibexa.co/security-advisories/ibexa-sa-2023-005-vulnerabilities-in-solr-search-and-file-downloads
