From 1.31.0 until 1.42.0, the Account API handlers in packages\/core\/src\/routes\/account\/third-party-tokens.ts allow a caller holding a same-user access token with only the openid scope to retrieve stored social or enterprise SSO provider access tokens through GET \/api\/my-account\/identities\/{target}\/access-token or GET \/api\/my-account\/sso-identities\/{connectorId}\/access-token. The handlers authenticate the user but do not require the identities scope that protects neighboring identity-detail operations, bypassing the intended Account API consent boundary. Exploitation requires federated token-set storage to be enabled and the affected user to have authenticated through a supported connector. A low-trust application can use the disclosed provider token against upstream APIs within that token&#8217;s granted scopes.
