CVE-2026-41492
CriticalSummary
Dgraph to otwartoźródłowa rozproszona baza danych GraphQL. W wersjach przed 25.3.3, Dgraph ujawnia linię poleceń procesu przez nieautoryzowany punkt końcowy /debug/vars na Alpha, co pozwala atakującemu na uzyskanie tokena administracyjnego.
Risk Assessment
Nieautoryzowany atakujący może wykorzystać ten token do uzyskania dostępu do punktów końcowych dostępnych tylko dla administratorów, co stwarza poważne zagrożenie dla bezpieczeństwa systemu.
Recommendation
Zaleca się aktualizację Dgraph do wersji 25.3.3, aby usunąć tę podatność oraz zabezpieczyć dostęp do wrażliwych punktów końcowych.

Original NVD description (English source)
Dgraph is an open source distributed GraphQL database. Prior to 25.3.3, Dgraphl exposes the process command line through the unauthenticated /debug/vars endpoint on Alpha. Because the admin token is commonly supplied via the --security "token=..." startup flag, an unauthenticated attacker can retrieve that token and replay it in the X-Dgraph-AuthToken header to access admin-only endpoints. This is a variant of the previously fixed /debug/pprof/cmdline issue, but the current fix is incomplete because it blocks only /debug/pprof/cmdline and still serves http.DefaultServeMux, which includes expvar's /debug/vars handler. This vulnerability is fixed in 25.3.3.
