CVE-2026-77970 Medium · 5.9 CWE-312 Aug 29, 2026

Sensitive fields nested in embedded values are not redacted in AshPaperTrail versions

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.

CVE-2026-77831 Low · 2.1 CWE-407 Aug 29, 2026

Algorithmic-complexity denial of service in AshPaperTrail full-diff list tracking

Inefficient Algorithmic Complexity vulnerability in ash-project ash_paper_trail allows a user who can submit a large array attribute to a paper-trailed create or update action to cause a denial of service through excessive CPU and memory use. With full-diff change tracking, AshPaperTrail.ChangeBuilders.FullDiff.ListChange pairs each prior array element against the new list by rebuilding the remaining-elements accumulator with acc ++ [tuple] on every step, copying the growing list each time, so the pairing scales cubically in the array length. Nothing bounds the length and the value comes straight from action input, so one request carrying a large accepted {:array, _} attribute forces tens of seconds of CPU and multi-gigabyte allocations. This issue affects ash_paper_trail: from 0.1.1 before 0.7.0.

CVE-2026-75847 Medium · 5.9 CWE-312 Aug 29, 2026

Sensitive attribute values stored in a non-sensitive public changes map in AshPaperTrail

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 the plaintext of sensitive? attributes. AshPaperTrail stores the values of tracked sensitive? attributes in the generated version resource's changes map, which is declared public? true and sensitive? false, so the values are returned by the version resource's default read action and printed in logs, inspect output, and error messages instead of being redacted. AshPaperTrail.Resource.Transformers.CreateVersionResource derives the changes map's sensitivity from the ignore_attributes list (the attributes excluded from changes) rather than from the tracked attributes actually stored in it, and ignore_attributes defaults to empty, so the flag is effectively always false. This issue affects ash_paper_trail: from 0.1.1 before 0.7.0.
