Vulnerability from fkie_nvd - Published: 2026-07-30 15:16 - Updated: 2026-07-30 17:16
Severity
Summary
Improper Isolation or Compartmentalization vulnerability in malach-it boruta (Elixir.Boruta.Openid module) allows attackers to register OpenID Connect clients with administrative privileges through the dynamic client registration entry point. Boruta.Openid.register_client/3 forwards caller-supplied registration parameters to the administrative client creation path without a public/admin field-level allowlist, so an unauthenticated registrant can set security-sensitive attributes including supported grant types, authorized scopes, PKCE enforcement, public refresh and revocation behavior, token lifetimes, and signing settings. The library does not distinguish between metadata a public registrant is allowed to set and administrative controls that should require operator approval.
This vulnerability is associated with program files lib/boruta/openid.ex and program routines 'Elixir.Boruta.Openid':register_client/3, 'Elixir.Boruta.Openid':parse_registration_params/2.
This issue affects boruta from 2.3.0 before 2.3.7.
