Duplicate Advisory: Cross Site Scripting in eZ Platform Ibexa Kernel
## Duplicate Advisory
This advisory has been withdrawn because it is a duplicate of GHSA-mrvj-7q4f-5p42. This link is maintained to preserve external references.

## Original Description
## Impact

In file upload it is possible by certain means to upload files like .html and .js. These may contain XSS exploits which will be run when links to them are accessed by victims.
Patches

## Patches

The fix consists simply of adding common types of scriptable file types to the configuration of the already existing filetype blacklist feature. See "Patched versions". As such, this can also be done manually, without installing the patched versions. This may be relevant if you are currently running a considerably older version of the kernel package and don't want to upgrade it at this time. Please see the settting "ezsettings.default.io.file_storage.file_type_blacklist" at:
https://github.com/ezsystems/ezplatform-kernel/blob/master/eZ/Bundle/EzPublishCoreBundle/Resources/config/default_settings.yml#L109
Important note

## Important note

You should adapt this setting to your needs. Do not add file types to the blacklist that you actually need to be able to upload. For instance, if you need your editors to be able to upload SVG files, then don't blacklist that. Instead, you could e.g. use an approval workflow for such content.

Download route allows filename change in eZpublish kernel
### 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.

Duplicate Advisory: User account enumeration in eZ Publish Ibexa Kernel
## Duplicate Advisory
This advisory has been withdrawn because it is a duplicate of GHSA-gmrf-99gw-vvwj. This link is maintained to preserve external references.

## Original Description

This Security Advisory is about a vulnerability in eZ Platform v1.13, v2.5, and v3.2, and in Ibexa DXP and Ibexa Open Source v3.3. The /user/sessions endpoint can let an attacker detect if a given username or email refers to a valid account. This can be detected through differences in the response data or response time of certain requests. The fix ensures neither attack is possible. The fix is distributed via Composer.
