Remediation Suggestions
-
Remove caller-controlled identity selection
- Delete the public or hidden
--open-idargument from the ordinary Skill entry point. - Do not treat argument suppression as an access-control mechanism.
- Delete the public or hidden
-
Use a trusted identity channel
- Accept identity only from an authenticated runtime integration.
- Bind the supplied identity to the invoking principal through a signed assertion, verified session, or mutually authenticated service channel.
- Maintain an explicit allowlist of trusted identity sources.
-
Require proof of account ownership
- Do not authenticate by submitting only
openIdormobile. - Require a server-verifiable credential, signed nonce, authorization code, or equivalent challenge-response mechanism.
- Disable identifier-only silent registration and login for this workflow.
- Do not authenticate by submitting only
-
Enforce authorization server-side
- Ensure history and report endpoints derive tenant and user scope from verified token claims rather than caller-submitted fields such as
pnaUserName. - Reject mismatches between authenticated token claims and requested account identifiers.
- Ensure history and report endpoints derive tenant and user scope from verified token claims rather than caller-submitted fields such as
-
Protect locally cached credentials
- Store tokens in an operating-system credential store or encrypted secret store rather than ordinary SQLite fields.
- Apply restrictive file permissions to any unavoidable local credential database.
- Expire and rotate tokens already issued through the identifier-only flow.
-
Separate default-user behavior from real accounts
- Use a narrowly scoped anonymous or device identity when no authenticated user exists.
- Prevent generated default identities from accessing records belonging to other users.
- Require explicit authenticated account linking before historical reports can be queried.
-
Add security tests
- Verify that arbitrary
--open-idvalues cannot produce credentials. - Test that one identity cannot list, fetch, or create records in anothe ...[truncated 147 chars]
