Summary
Dgraph Vulnerable to DQL Injection via checkUserPassword GraphQL Query
Details

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.
