CVE-2026-65770 is a critical remote code execution vulnerability in Microsoft Azure Managed Instance for Apache Cassandra. The flaw is caused by improper neutralization of argument delimiters in a command, i.e., argument injection. Insufficient handling of attacker-controlled parameters can allow crafted input to alter command arguments processed by the service, resulting in execution of arbitrary code in the context of the vulnerable cloud service component. The vulnerability is remotely reachable over the network, requires no authentication or user interaction, and is associated with CVSS v3.1 vector AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:H.
