SCA: security update for github.com/dgraph-io/dgraph/v25 (GHSA-x92x-px7w-4gx4)

critical Tenable Self-Hosted Container Security Plugin ID 440822

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - Dgraph is an open source distributed GraphQL database. Prior to 25.3.3, a vulnerability has been found in
 Dgraph that gives an unauthenticated attacker full read access to every piece of data in the database.
 This affects Dgraph's default configuration where ACL is not enabled. The attack requires two HTTP POSTs
 to port 8080. The first sets up a schema predicate with @unique @index(exact) @lang via /alter (also
 unauthenticated in default config). The second sends a crafted JSON mutation to /mutate?commitNow=true
 where a JSON key contains the predicate name followed by @ and a DQL injection payload in the language tag
 position. The injection exploits the addQueryIfUnique function in edgraph/server.go, which constructs DQL
 queries using fmt.Sprintf with unsanitized predicateName that includes the raw pred.Lang value. The Lang
 field is extracted from JSON mutation keys by x.PredicateLang(), which splits on @, and is never validated
 by any function in the codebase. The attacker injects a closing parenthesis to escape the eq() function,
 adds an arbitrary named query block, and uses a # comment to neutralize trailing template syntax. The
 injected query executes server-side and its results are returned in the HTTP response. This vulnerability
 is fixed in 25.3.3. (CVE-2026-41328)

Solution

Update the github.com/dgraph-io/dgraph/v25 library and its related packages to version 25.3.3 or later.
