Prior to @tinacms\/auth 1.1.4 and next-tinacms-azure 15.0.1, isAuthorized accepts a request-controlled clientID and asks isUserAuthorized to validate the bearer token against that selected TinaCloud app instead of the self-hosted site&#8217;s configured app. An attacker with any TinaCloud account can submit the attacker&#8217;s own app ID and valid token to a victim endpoint, causing TinaCloudBackendAuthProvider or an affected media authorized callback to accept the attacker&#8217;s verified status across the tenant boundary. The vulnerable logic is present in packages\/@tinacms\/auth\/src\/index.ts and packages\/next-tinacms-azure\/src\/auth.ts. Successful exploitation permits media listing, reading, upload, or deletion and, when TinaCloudBackendAuthProvider is used, GraphQL read, create, update, and delete operations on the victim&#8217;s content without a victim account or victim interaction.
