  "details": "Deserialization of Untrusted Data vulnerability in Apache Storm.\n\nVersions Affected:\nbefore 2.8.6.\n\n\nDescription:\nWhen processing topology credentials submitted via the Nimbus Thrift API, Storm deserializes the base64-encoded TGT blob using ObjectInputStream.readObject() without any class filtering or validation. An authenticated user with topology submission rights could supply a crafted serialized object in the \"TGT\" credential field, leading to remote code execution in both the Nimbus and Worker JVMs.\n\n\nMitigation:\n2.x users should upgrade to 2.8.6.\n\n\nUsers who cannot upgrade immediately should monkey-patch an ObjectInputFilter allow-list to ClientAuthUtils.deserializeKerberosTicket() restricting deserialized classes to javax.security.auth.kerberos.KerberosTicket and its known dependencies. A guide on how to do this is available in the release notes of 2.8.6.\n\nCredit: This issue was discovered by K.",
