GHSA-g95c-xc83-8353 Ibexa DXP Download route allows filename change

• Packagist ibexa/core: >= 4.5.0, < 4.5.4 → fixed in 4.5.4

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 ibexa/core, see "Patched versions". An advisory is also published for ezsystems/ezpublish-kernel and ezsystems/ezplatform-kernel, please see those repositories. Commit: https://github.com/ibexa/core/commit/704f221031ea4e32bd5510fe4c1fa8e0f664cbd4 Workarounds None, other than blocking all downloads.
