CVE-2026-75847
MediumCVSS 5.9Summary
The ash_paper_trail library (ash-project) has a cleartext storage of sensitive information vulnerability. An attacker with read access to the generated version resource can recover the plaintext of sensitive? attributes. These values are stored in the changes map, which is public and not marked as sensitive, so they are returned by the default read action and printed in logs and error messages.
Risk Assessment
Anyone with access to version resources can obtain sensitive data, leading to confidentiality breaches. The vulnerability affects versions from 0.1.1 before 0.7.0.
Recommendation
Update ash_paper_trail to version 0.7.0 or later, which includes the fix. Restrict access to version resources and logs.
Other vulnerabilities in ash_paper_trail
See all- CVE-2026-77970Medium
The ash_paper_trail library (ash-project) has a cleartext storage of sensitive information vulnerability. An attacker with read access to the generated version resource can recover sensitive values nested inside embedded resources, unions, or lists. The sensitive_attributes :redact and :ignore only act on top-level attributes, not descending into nested structures.
- CVE-2026-77831Low
The ash_paper_trail library (ash-project) has an inefficient algorithmic complexity vulnerability. A user who can submit a large array attribute to a paper-trailed create or update action can cause a denial of service through excessive CPU and memory use. This results from cubic scaling of list comparison operations in full-diff mode.
Original NVD description (English source)
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.
