Prior to version 25.3.4, the `checkUserPassword` GraphQL query in Dgraph is vulnerable to DQL (Dgraph Query Language) injection. User-supplied password values are interpolated directly into a DQL `checkpwd()` query via `fmt.Sprintf` without any escaping or parameterization. An attacker can inject a password containing a double-quote character to break out of the DQL string literal and append arbitrary DQL query blocks. Version 25.3.4 patches the issue."}],"affected":[{"source":"security-advisories@github.com","affectedData":[{"vendor":"dgraph-io","product":"dgraph","versions":[{"version":"< 25.3.4","status":"affected"}]}]}],"metrics":{"cvssMetricV31":[{"source":"security-advisories@github.com","type":"Secondary","cvssData":{"version":"3.1","vectorString":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N","baseScore":7.5,"baseSeverity":"HIGH","attackVector":"NETWORK","attackComplexity":"LOW","privilegesRequired":"NONE","userInteraction":"NONE","scope":"UNCHANGED","confidentialityImpact":"HIGH","integrityImpact":"NONE","availabilityImpact":"NONE"},"exploitabilityScore":3.9,"impactScore":3.6}],"ssvcV203":[{"source":"134c704f-9b21-4f2e-91b3-4a467353bcc0","ssvcData":{"timestamp":"2026-07-09T13:28:28.118081Z","id":"CVE-2026-44840","options":[{"exploitation":"poc"},{"automatable":"yes"},{"technicalImpact":"partial"}],"role":"CISA Coordinator","version":"2.0.3"}}]},"weaknesses":[{"source":"security-advisories@github.com","type":"Secondary","description":[{"lang":"en","value":"CWE-943"}]}],"references":[{"url":"https://github.com/dgraph-io/dgraph/commit/cee702c93f141eeb0c96a81f70830ec9e459efac","source":"security-advisories@github.com"},{"url":"https://github.com/dgraph-io/dgraph/releases/tag/v25.3.4","source":"security-advisories@github.com"},{"url":"https://github.com/dgraph-io/dgraph/security/advisories/GHSA-q2m9-6jp9-c6mc","source":"security-advisories@github.com"},{"url":"https://github.com/dgraph-io/dgraph/security/advisories/GHSA-q2m9-6jp9-c6mc","source":"134c704f-9b21-4f2e-91b3-4a467353bcc0"}]}
