How NewScan reports it
COMPONENT VERSION RANGE
NewScan fingerprints google.golang.org/grpc from its response and reports this CVE when the detected version falls inside the affected range below.
Added 2026-09-02 (/daily-cve). Version source is the exact google.golang.org/grpc module pin in an anonymously served go.mod, already parsed by mine_versions; the module path is the pack key, so the join needs no code or alias. Releases through 1.83.0 retain a separate receive-buffer entry for every tiny DATA frame, allowing unauthenticated streams to exhaust heap memory. Version-match only: actively fragmenting millions of frames is destructive denial-of-service testing and is outside policy.
