What is CVE-2025-26467?

A privilege escalation vulnerability exists in Apache Cassandra where a user granted MODIFY permissions on all keyspaces can execute unsafe actions, allowing them to elevate their privileges to superuser status within a targeted Cassandra cluster. Operators who have assigned data MODIFY permissions should verify and review their data access controls to prevent potential exploitation. Particularly, users running version 4.0.16 are advised to upgrade to version 4.0.17 for resolution, while users on versions 3.0, 3.11, 4.1, and 5.0 should follow the recommendations outlined in associated advisories.
