CyberRota Analysis
AI-GeneratedThe vulnerability allows an attacker to overwrite existing records in the ETS or Mnesia data layers of the ash-project ash by using a create action with a primary key that already exists, bypassing intended access controls. This can lead to unauthorized data manipulation, potentially compromising the integrity of the application’s data. Organizations utilizing affected versions of ash (from 0.4.0 to before 3.32.2) should prioritize patching this issue to prevent potential data loss or corruption.

Original NVD Description
Improper Access Control vulnerability in ash-project ash lets a create action overwrite an existing record when the ETS or Mnesia data layer is used, because neither enforced primary-key uniqueness on insert. Unlike a SQL data layer, whose unique primary-key constraint rejects a duplicate, the ETS and Mnesia data layers implemented create as a keyed insert that replaces any existing entry with the same primary key (lib/ash/data_layer/ets/ets.ex, lib/ash/data_layer/mnesia/mnesia.ex). An actor who can set the primary key on a create (for example a user-supplied string or integer key) can submit a create whose key matches an existing record and silently overwrite it, destroying and replacing another entity's data without going through the update action or its policies. The fix rejects a create whose primary key already exists with an already-taken error, and only allows duplicates for keyless resources. This issue affects ash: from 0.4.0 before 3.32.2.
