Affected packages
• Go github.com/pomerium/pomerium: >= 0.14.0, < 0.15.6 → fixed in 0.15.6
Description
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
