{"apiVersion":"1.0","identifier":"CVE-2026-80346","description":"StarRocks performs no privilege check when a legacy synchronous materialized view is dropped. Every other statement type routed through AuthorizerStmtVisitor calls into Authorizer before execution, but visitDropMaterializedViewStatement returns immediately with a comment stating the check happens in execution logic. That holds only for asynchronous materialized views: LocalMetastore.dropMaterializedView calls Authorizer.checkMaterializedViewAction inside a branch taken when the resolved table is a MaterializedView. A legacy synchronous materialized view is stored as a rollup index on an OlapTable rather than a MaterializedView, so the other branch runs, reaching AlterJobMgr.processDropMaterializedView and MaterializedViewHandler, neither of which contains any Authorizer call. The former locates the target by scanning every OlapTable in the named database for a matching rollup index, and the latter validates only table state and name conflicts. Any authenticated account can therefore drop a legacy synchronous materialized view belonging to any database, holding no grant on the view, the base table or the database, and the drop is indistinguishable from an authorized one.","publishedAt":"2026-08-26T10:16:42","lastModifiedAt":null,"sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-80346","cvssScore":7.1,"cvssVector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:H/A:L","epssProbability":0.00386,"riskScore":0.73,"affectedProduct":"StarRocks","affectedVersions":"unknown","vulnerabilityType":"Other","operatingSystems":[],"links":{"self":"https://www.redsauce.net/api/cves/CVE-2026-80346","webPages":{"es":"https://www.redsauce.net/es/cves/CVE-2026-80346","en":"https://www.redsauce.net/en/cves/CVE-2026-80346","fr":"https://www.redsauce.net/fr/cves/CVE-2026-80346","pt":"https://www.redsauce.net/pt/cves/CVE-2026-80346","de":"https://www.redsauce.net/de/cves/CVE-2026-80346","sk":"https://www.redsauce.net/sk/cves/CVE-2026-80346","el":"https://www.redsauce.net/el/cves/CVE-2026-80346"},"source":"https://nvd.nist.gov/vuln/detail/CVE-2026-80346"}}
