The Operator should be able to safely issue Accounts to other entities which it does not fully trust.\n\nA malicious Account could create and sign a User JWT with a state not created by the normal tooling, such that decoding by the NATS JWT library (written in Go) would attempt a nil dereference, aborting execution.\n\nThe NATS Server is known to be impacted by this.\n\n\n## Affected versions\n\n#### JWT library\n\n * all versions prior to 1.1.0\n\n#### NATS Server\n\n * Version 2 prior to 2.1.9\n\n\n## Impact\n\n#### JWT library\n\n * Programs would nil dereference and panic, aborting execution by default.\n\n#### NATS server\n\n * Denial of Service caused by process termination\n\n\n## Workaround\n\nIf your NATS servers do not trust any accounts which are managed by untrusted entities, then malformed User credentials are unlikely to be encountered.\n\n\n## Solution\n\nUpgrade the JWT dependency in any application using it.\n\nUpgrade the NATS server if using NATS Accounts.",
