UnverifiedAuthorization protocols such as OAuth provide a certain degree of permission boundary protection, but the actual scope of authorization depends on whether users carefully read the permissions request list.70% similarUnverifiedRevocable access permissions are usually implemented through short-lived tokens (such as OAuth 2.0 short-lived Access Tokens) or dynamic credentials, and operations staff can revoke them immediately upon detecting abnormal behavior.67% similarUnverifiedSpecific strategies to prevent the OAuth email auto-linking vulnerability include: requiring the email to be verified, separating registration from linking, using a provider + provider_user_id combined identifier, secondary confirmation, and auditing and logging.67% similarUnverifiedOAuth 2.0 is an authorization delegation protocol in which the user does not have to hand over their password to a third-party app; instead, an authorization server issues an access token and a refresh token. The access token typically has a validity period of only a few tens of minutes to a few hours, and after it expires it must be exchanged for a new token using the refresh token; the refresh token itself may also be revoked or rotated.66% similar
