Description
Dgraph is an open source distributed GraphQL database. Versions 25.3.1 and prior contain an unauthenticated credential disclosure vulnerability where the /debug/pprof/cmdline endpoint is registered on the default mux and reachable without authentication, exposing the full process command line including the admin token configured via the --security "token=..." startup flag. An attacker can retrieve the leaked token and reuse it in the X-Dgraph-AuthToken header to gain unauthorized access to admin-only endpoints such as /admin/config/cache_mb, bypassing the adminAuthHandler token validation. This enables unauthorized privileged administrative access including configuration changes and operational control actions in any deployment where the Alpha HTTP port is reachable by untrusted parties. This issue has been fixed in version 25.3.2.
