File validation can be configured to reject certain files by file type. When this happens, validation fails, and the content can't be published. However, the file can be saved when saving the content draft. This means unwanted files can be present in storage, even if they are not easily accessible due to the content not being published. The fix ensures these unwanted file types are never stored. An attacker would …
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 …

This also applies to any other user that has the role / assign policy. Any subtree limitation in place does not have any effect.

This implementation was found to not be good enough in some situations. The fix replaces this with constant time functionality, configured in the new security.yml parameter 'ibexa.security.authentication.constant_auth_time'. It will log a warning if the constant time is …
Object state limitation is a policy you can use in your roles to limit access to content based on specific object state values. Due to a flawed earlier update, these limitations were ineffective in releases made since February 16th 2022. They would grant access to the given content regardless of the object state. Depending on how your frontent is designed, knowing the URL to the content may or may not …
