description

Affected supertokens-core releases can mishandle management requests for an unknown tenant when an older supported CDI version is selected. An unauthenticated attacker who can reach the Core service may create and enumerate application roles without supplying a valid API key.

mitigation

Upgrade supertokens-core to 11.3.6, 11.4.6, or 12.0.8 or later, as appropriate for the deployed release line. Restrict network access to Core management endpoints until the upgrade is complete.

fixed in 12.0.8, 11.4.6, 11.3.6
