## Overview

### Impact
Changes to the OIDC claims of a user after initial login are not reflected in policy evaluation when using [`allowed_idp_claims`](https://www.pomerium.com/reference/#allowed-idp-claims) as part of policy.  If using `allowed_idp_claims` and a user's claims are changed, Pomerium can make incorrect authorization decisions.

### Patches
v0.15.6

### Workarounds
- Clear data on `databroker` service by clearing redis or restarting the in-memory databroker to force claims to be updated
