Description
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.
