CVE-2021-41230
November 05, 2021
Pomerium is an open source identity-aware access proxy. In affected versions changes to the OIDC claims of a user after initial login are not reflected in policy evaluation when using "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. This issue has been resolved in v0.15.6. For users unable to upgrade clear data on "databroker" service by clearing redis or restarting the in-memory databroker to force claims to be updated.
