Detailsinfo

A vulnerability, which was classified as problematic, was found in ash-project ash_phoenix up to 2.3.24. Affected is the function Ash.Resource.Info.related of the component Filter. The manipulation of the argument field with an unknown input leads to a authorization vulnerability. CWE is classifying the issue as CWE-639. The system's authorization functionality does not prevent one user from gaining access to another user's data or record by modifying the key value identifying the data. This is going to have an impact on confidentiality. CVE summarizes:

Authorization Bypass Through User-Controlled Key vulnerability in ash-project ash_phoenix lets an attacker who controls filter form parameters filter across relationships the resource author marked non-public, turning the returned rows into a boolean oracle over private related data. AshPhoenix.FilterForm resolved every relationship hop in the user-supplied path with Ash.Resource.Info.related/2, which traverses private relationships, and only checked the terminal field for publicity. parse_path_and_field/2 also rewrote a field naming a relationship into an extra path segment, so field=some_private_rel was accepted too. Both path and field come straight from form params, and the resulting ref went to Ash.Query.do_filter/2 without the public-only enforcement of Ash.Filter.parse_input/2. The fix resolves each hop with Ash.Resource.Info.public_relationship/2, rejecting the first non-public hop, and requires the terminal field to be public. This issue affects ash_phoenix: from 0.6.0-rc.1 before 2.3.25.
