CVE-2026-41492: CWE-200: Exposure of Sensitive Information to an Unauthorized Actor in dgraph-io dgraph
Dgraph versions prior to 25. 3. 3 expose sensitive process command line information via an unauthenticated /debug/vars endpoint on the Alpha service. This exposure allows attackers to retrieve the admin token commonly passed as a startup flag, enabling unauthorized access to admin-only endpoints. The vulnerability is a variant of a previously fixed issue but was incompletely remediated, leaving the /debug/vars endpoint accessible. This issue is rated critical with a CVSS score of 9. 8 and is fixed in version 25. 3. 3.
AI Analysis
Technical Summary
Dgraph, an open source distributed GraphQL database, has a critical vulnerability (CVE-2026-41492) in versions before 25.3.3 where the process command line is exposed through the unauthenticated /debug/vars endpoint on the Alpha node. Since the admin token is often supplied via the --security "token=..." startup flag, an attacker can retrieve this token from the exposed command line and use it in the X-Dgraph-AuthToken header to gain unauthorized admin access. This vulnerability is a variant of a previously fixed issue involving /debug/pprof/cmdline, but the prior fix did not block /debug/vars, leaving sensitive information exposed. The vulnerability is fixed in version 25.3.3.
Potential Impact
An unauthenticated attacker can obtain the admin token by accessing the /debug/vars endpoint, which exposes the process command line containing the token. With this token, the attacker can impersonate an admin and access admin-only endpoints, potentially leading to full compromise of the Dgraph service. The CVSS score of 9.8 reflects the critical impact on confidentiality, integrity, and availability.
Mitigation Recommendations
Upgrade Dgraph to version 25.3.3 or later, where this vulnerability is fixed. Since no official patch or temporary fix is indicated beyond this version, applying the update is the recommended remediation. Until upgraded, restrict access to the /debug/vars endpoint and avoid passing sensitive tokens via command line flags if possible.
