What is CVE-2023-46129?

The NATS.io nkeys library introduced an encryption feature for authentication callouts but contained an implementation flaw. The logic passed an array by value into an internal function, leading to the population of the encryption key with an all-zeros value. Consequently, any data encrypted using this method was effectively unsecured, though the signing function remained unaffected. Users utilizing nkeys in conjunction with NATS Server versions 2.10.0 to 2.10.3 should update to nkeys library version 0.4.6 or later, as it addresses this critical encryption handling bug. There are no known workarounds, making prompt updates essential for maintaining security.

Affected Version(s)

nkeys >= 2.10.0, < 2.10.4 < 2.10.0, 2.10.4

nkeys >= 0.4.0, < 0.4.6 < 0.4.0, 0.4.6
