GHSA-J6WP-3859-VXFG

Vulnerability from github – Published: 2021-11-10 16:52 – Updated: 2021-11-08 21:37
VLAI
Summary
OIDC claims not updated from Identity Provider in Pomerium
Details

Impact

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.

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
