CVE-2026-63637 Details
Description
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.
A vulnerability in Dgraph, an open-source distributed GraphQL database, allows for DQL injection via unvalidated regexp filter arguments in GraphQL queries or mutations. This issue affects Dgraph versions through 25.3.7. The vulnerability arises because the 'maybeQuoteArg' function in the query rewriter bypasses sanitization for 'regexp' filters, allowing crafted values to inject DQL operators, access unintended nodes, or manipulate deletion targets. Exploitation can lead to unauthorized data disclosure or mass data modification and deletion.
Users can update to Dgraph version 25.3.8, where this vulnerability has been patched. The update is available on the Dgraph GitHub releases page.
