CVE-2026-80346 StarRocks CVE debrief

Who should care

StarRocks administrators and users with access to materialized views should assess their exposure and ensure proper authorization is in place. This includes verifying the exposure of legacy synchronous materialized views in StarRocks deployments and ensuring proper authorization is configured for materialized views. Additionally, defenders should monitor for suspicious activity related to materialized view drops and review compensating controls for exposed

Why it matters

CVE-2026-80346 allows unauthorized drops of legacy synchronous materialized views in StarRocks, impacting data integrity and confidentiality.

• Defenders must verify exposure of legacy synchronous materialized views in StarRocks deployments
• Unauthorized drops of materialized views can occur without proper authorization
• Defensive priority is high due to potential for data loss or corruption

Technical summary

StarRocks performs no privilege check when a legacy synchronous materialized view is dropped, allowing any authenticated account to drop such views without proper authorization. The vulnerability is due to the lack of authorization checks in the drop materialized view statement, which can be exploited by any authenticated user. This issue impacts data integrity and confidentiality, as unauthorized drops can lead to data loss or corruption. Defenders should prioritize verifying exposure of legacy synchronous materialized views in their StarRocks deployments and ensure proper authorization is in place.
