Description
Zipline from 4.2.0 before 4.6.2 contains an information disclosure vulnerability that logs sensitive environment variable values, such as OAUTH_OIDC_CLIENT_SECRET, without redaction at startup. Attackers with access to system journal or docker logs can obtain OAuth2 client secrets and use them to exchange intercepted OAuth2 callbacks for valid tokens.
