CVE-2026-44840

highCVSS 7.5covered by 1 sourcefirst seen 2026-07-08

Dgraph is an open source distributed GraphQL database. 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.
