Sources and claim methodology

Upstream source description

Cleartext Storage of Sensitive Information vulnerability in ash-project ash_paper_trail allows an attacker with read access to the generated version resource to recover sensitive values nested inside embedded resources, unions, or lists. sensitive_attributes :redact and :ignore only act on the tracked resource's top-level attributes. maybe_redact_changes/3 and the stored-action-input path in AshPaperTrail.Resource.Changes.CreateNewVersion derive the sensitive set from the resource's own attributes and never descend into embedded, union, or list values, so a non-sensitive attribute or action argument that holds an embed with a sensitive? field (for example an accepted credentials embed carrying a token) is written to the version table in cleartext. This issue affects ash_paper_trail: from 0.3.0 before 0.7.0.
