      <title>CVE-2026-81322 — Cloaked plaintext leaks through a non-sensitive action argument in AshCloak</title>
      <link>https://vulnerability.circl.lu/vuln/cve-2026-81322</link>
      <description>&lt;p&gt;&lt;strong&gt;Affected:&lt;/strong&gt; ash-project ash_cloak&lt;/p&gt;
&lt;p&gt;Exposure of Sensitive Information to an Unauthorized Actor vulnerability in ash-project ash_cloak allows anyone with access to logs, error trackers, or crash reports, or anyone who can trigger a validation error, to recover the plaintext of a field the library encrypts.&lt;/p&gt;
&lt;p&gt;AshCloak.Transformers.SetUpEncryption removes each cloaked attribute from the action&amp;#39;s accept list and adds an action argument that carries the plaintext into the encryption change. That argument is built with sensitive?: attr.sensitive?, inheriting the flag from the source attribute, so a cloaked attribute declared without sensitive? true produces a non-sensitive argument. It is the only place the cleartext value lives, and the one place Ash will not redact: it appears verbatim in inspect(changeset), Ash.Error.Invalid and validation error messages, telemetry, :sys dumps, and error-tracker payloads. The generated encrypted attribute and decrypt calculation are already hardcoded sensitive.&lt;/p&gt;
&lt;p&gt;This issue affects ash_cloak: from 0.1.0 before 0.4.0.&lt;/p&gt;</description>
