Short explanation
SuperTokens Core contains a high-severity vulnerability where unknown tenant paths and older cdi-version values can bypass API key and public-tenant enforcement.
Allows an unauthenticated caller to create and enumerate application roles without a valid API key.
What should be done?
- Update to versions 11.3.6, 11.4.6, and 12.0.8
- Follow vendor advisories and security releases
Chain of evidence and sources
SuperTokens Core, bilinmeyen kiracı yolları ve eski cdi-version değerleri kullanıldığında API anahtarı ile genel kiracı denetimlerini atlatabilir.
Kimliği doğrulanmamış bir çağırıcı PUT ve GET istekleri ile geçerli bir API anahtarı olmadan uygulama rolleri oluşturabilir ve listeleyebilir.
Show the technical text from the sources
SuperTokens Core is an open source authentication server. Prior to 11.3.6, 11.4.6, and 12.0.8, app-specific management requests using an unknown tenant path and an older supported cdi-version can bypass API-key and public-tenant enforcement. In src/main/java/io/supertokens/webserver/WebserverAPI.java, checkIPAccess and assertThatAPIKeyCheckPasses suppress TenantOrAppNotFoundException, while the later app-specific handler resolves app/public storage and the public-tenant guard applies only to CDI versions 5.0 and later. An unauthenticated caller able to reach the Core endpoint can therefore use PUT /ghosttenant/recipe/role and GET /ghosttenant/recipe/roles to create and enumerate application roles without a valid API key. This issue is fixed in versions 11.3.6, 11.4.6, and 12.0.8.
