Preliminary research
Unauthenticated RCE in Taskcluster via a GraphQL filter reaching sift's `$where`
Unauthenticated RCE in Taskcluster web-server via GraphQL filter argument (sift $where)
AI-collected research leads through 22 September 2026, including targeted additions between broader sweeps. Unranked, incomplete, not community-vetted, and subject to change.
Traces an anonymous Taskcluster GraphQL filter into sift’s JavaScript-evaluating $where operator. The report identifies a scope that guarantees nonempty input and uses propagated error text to observe service-side execution, illustrating how API reachability and collection behavior expose an established injection sink.
