EEF-CVE-2026-75847

## Summary

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.

## Configuration

The tracked resource must declare one or more sensitive? attributes that are not listed in ignore\_attributes. Exposure requires read access to the generated version resource, which ships with defaults \[:read, ...\] and a changes field that is selectable by default.
