GMS-2023-136: JWT audience claim is not verified

January 25, 2023

All versions of Argo CD starting with v1.8.2 is vulnerable to an improper authorization bug causing the API to accept certain invalid tokens.

OIDC providers include an aud (audience) claim in signed tokens. The value of that claim specifies the intended audience(s) of the token (i.e. the service or services which are meant to accept the token).
