CVE-2026-63637: Dgraph-Io Dgraph

High severity, CVSS 8.6. EPSS: 0.4% chance of exploitation in the next 30 days.

Dgraph is an open source distributed GraphQL database. Prior to 25.3.8, maybeQuoteArg in graphql/resolve/query_rewriter.go passes regexp filter strings into generated DQL without quoting or validating the /pattern/flags form, allowing crafted GraphQL query or mutation filters to inject DQL operators, disclose unintended nodes, or expand modification and deletion targets. This issue is fixed in version 25.3.8.

Affected products

• Dgraph-Io Dgraph: before 25.3.8 (fixed in 25.3.8)
