CVE-2026-82723 Details
Description
Insertion of Sensitive Information into Log File vulnerability in team-alembic AshAuthentication allows disclosure of user password digests to readers of the audit store. The audit_log add-on builds each entry's extra_data in AshAuthentication.AddOn.AuditLog.Auditor.build_extra_data/4, which takes :actor from the action callback context verbatim. Any audited action invoked with actor: set to a user record therefore deposits that record, including its hashed_password attribute, into the audit entry. The same module already collapses the audited identity to an opaque string via AshAuthentication.user_to_subject/1 and filters params against the strategy's configured allow-list, so the actor is the only stored value that reaches the audit store unfiltered. Marking the attribute sensitive?: true does not help, because that redacts inspect/1 output rather than JSON encoding or raw-term storage. There is no attacker-controlled trigger and no network disclosure path: entries accumulate from ordinary authenticated activity, and an attacker's own requests deposit only their own digest. Exploitation requires independent read access to the audit store, such as database credentials, an audit role, a backup, or a log shipper, at which point the digests support offline password attack against every active account. Whether the material persists depends on the data layer, since raw-term stores keep it verbatim while a SQL store raises Protocol.UndefinedError and drops the entry unless the user resource derives Jason.Encoder. This issue affects ash_authentication: from 4.12.0 before 4.15.0 and from 5.0.0-rc.0 before 5.0.0-rc.2.
A vulnerability in the Team-Alembic AshAuthentication library's audit logging feature allows for the unauthorized disclosure of user password digests. This issue arises because the audit_log add-on captures and stores the entire user resource, including the hashed_password, in the audit entries' extra_data. The vulnerability affects AshAuthentication versions 4.12.0 prior to 4.15.0 and 5.0.0-rc.0 prior to 5.0.0-rc.2.
Users can upgrade to AshAuthentication version 5.0.0-rc.2 or later, where the vulnerability has been addressed. For those on the 4.x line, the advisory recommends backporting the fix from the 5.x version.
