Critical CVSS 10
CVE-2026-65770
Microsoft Azure Managed Instance For Apache Cassandra
Improper neutralization of argument delimiters in a command ('argument injection') in Azure Managed Instance for Apache Cassandra allows an unauthorized attacker to execute code over a network.
What this means
- Exposure

- Impact
- An attacker can read sensitive data, modify or destroy data and take the service offline. The impact spreads beyond the vulnerable component into other parts of the system.
- Weakness
- The attacker slips extra arguments into the invocation of an external program.
- Likelihood
- Its EPSS score stays low: nothing points to imminent exploitation, which is no reason to leave it unpatched.
