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."}, {"lang": "es", "value": "Dgraph es una base de datos GraphQL distribuida de c\u00f3digo abierto. Antes de la versi\u00f3n 25.3.3, Dgraph expone la l\u00ednea de comandos del proceso a trav\u00e9s del endpoint /debug/vars no autenticado en Alpha. Dado que el token de administrador se suele suministrar a trav\u00e9s del flag de inicio --security \u2019token=...\u2019, un atacante no autenticado puede recuperar ese token y reutilizarlo en el encabezado X-Dgraph-AuthToken para acceder a endpoints solo para administradores.
