DescriptionNVD

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.

AnalysisAI

Dgraph distributed GraphQL database versions ≤25.3.1 expose admin authentication tokens through an unauthenticated /debug/pprof/cmdline endpoint, allowing remote attackers to retrieve the token from process command line arguments and gain full administrative access to the database. The vulnerability combines unauthenticated information disclosure (CWE-200) with subsequent authentication bypass, enabling configuration changes and operational control. …

RemediationAI

Within 24 hours: Identify all Dgraph instances running version ≤25.3.1 using inventory/asset management systems and disable or restrict network access to the /debug/pprof/cmdline endpoint if immediate patching is not possible. Within 7 days: Apply vendor-released patch to version 25.3.2 or later across all Dgraph deployments; validate patch application in test environments first. …
