CVE-2021-44521 [CRITICAL] CWE-94 CVE-2021-44521: When running Apache Cassandra with the following configuration: enable_user_defined_functions: true When running Apache Cassandra with the following configuration: enable_user_defined_functions: true enable_scripted_user_defined_functions: true enable_user_defined_functions_threads: false it is possible for an attacker to execute arbitrary code on the host. The attacker would need to have enough permissions to create user defined functions in the

CVE-2015-0225 [HIGH] CWE-77 CVE-2015-0225: The default configuration in Apache Cassandra 1.2.0 through 1.2.19, 2.0.0 through 2.0.13, and 2.1.0 The default configuration in Apache Cassandra 1.2.0 through 1.2.19, 2.0.0 through 2.0.13, and 2.1.0 through 2.1.3 binds an unauthenticated JMX/RMI interface to all network interfaces, which allows remote attackers to execute arbitrary Java code via an RMI request.

CVE-2025-23015 [HIGH] CWE-267 CVE-2025-23015: Privilege Defined With Unsafe Actions vulnerability in Apache Cassandra. An user with MODIFY permiss Privilege Defined With Unsafe Actions vulnerability in Apache Cassandra. An user with MODIFY permission ON ALL KEYSPACES can escalate privileges to superuser within a targeted Cassandra cluster via unsafe actions to a system resource. Operators granting data MODIFY permission on all keyspaces on affected versions should review data access rules for po

CVE-2026-27314 [HIGH] CWE-267 CVE-2026-27314: Privilege escalation in Apache Cassandra 5.0 on an mTLS environment using MutualTlsAuthenticator all Privilege escalation in Apache Cassandra 5.0 on an mTLS environment using MutualTlsAuthenticator allows a user with only CREATE permission to associate their own certificate identity with an arbitrary role, including a superuser role, and authenticate as that role via ADD IDENTITY. Users are recommended to upgrade to version 5.0.7+, which fixes this
