CVE-2026-77970Public exploit

Sensitive-data disclosure via shallow audit-log redaction

Published Aug 30, 2026 · Updated Aug 30, 2026

Cleartext storage in Ash Framework AshPaperTrail 0.3.0 through 0.6.0 allows attackers to recover nested secrets via reads of generated version resources. maybe_redact_changes/3 and the stored-action-input path derive a flat sensitive-field set from only top-level resource attributes, then persist embedded, union, map, or list values without recursively redacting sensitive fields. Exposure requires :redact or :ignore mode, a nested sensitive field inside a versioned attribute or accepted action input, and read access to the generated version resource.
