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.
Detection & mitigation playbook
VulnerabilityDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for the affected component. O3's reachability analysis confirms whether the vulnerable code path is actually invoked in your application, so you act on real exposure instead of every transitive match.
Remediation status
No patched version of the affected component has shipped for CVE-2026-80346 yet. Where your build allows, override or pin the dependency away from the vulnerable range, and apply any maintainer-recommended mitigation.
Mitigate without a patch
If you can't upgrade right away: gate or disable the affected feature, validate untrusted input at the boundary, and avoid passing attacker-controlled data into the vulnerable path. O3's runtime protection blocks exploitation in production as an interim safeguard until the upgrade lands.
How O3 protects you
O3 pinpoints whether CVE-2026-80346 is reachable in your code and exactly where to fix it, then blocks exploitation in production at runtime until the patched version is deployed.
Tailored to CVE-2026-80346. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
