Vulnerability Description

Pocket ID is an OIDC provider that allows users to authenticate with their passkeys to your services. Prior to 2.6.0, The createTokenFromRefreshToken function (oidc_service.go) validates the refresh token's cryptographic integrity but does not re-validate the user's current authorization state before issuing new tokens. This allows (1) the client to refresh the token indefinitely after authorization revocation, (2) the refresh token to continue to work after the account is disabled, and (3) the token to work after the client is removed from the group. This vulnerability is fixed in 2.6.0.
