Which packages are affected by CVE-2026-44840?

CVE-2026-44840 affects the following packages: github.com/dgraph-io/dgraph/v25 (Go). Ecosystems affected: Go.

How do I fix CVE-2026-44840?

Update github.com/dgraph-io/dgraph/v25 to 25.3.4 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2026-44840 is resolved across your whole dependency graph.

How do I detect CVE-2026-44840 in my Go dependencies?

Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for github.com/dgraph-io/dgraph/v25. O3's reachability analysis confirms whether the vulnerable code path is actually invoked in your application, so you act on real exposure instead of every transitive match.

How do I mitigate CVE-2026-44840 if there is no patch (or I can't update yet)?

If you can't upgrade right away: gate or disable the affected feature, validate untrusted input at the boundary, and avoid passing attacker-controlled data into the vulnerable path. O3's runtime protection blocks exploitation in production as an interim safeguard until the upgrade lands.

How does O3 Security protect against CVE-2026-44840?

O3 pinpoints whether CVE-2026-44840 is reachable in your code and exactly where to fix it, then blocks exploitation in production at runtime until the patched version is deployed.

Is CVE-2026-44840 actively exploited in the wild?

No public exploit code has been indexed for CVE-2026-44840 yet. This does not mean the vulnerability cannot be exploited — absence of public exploits does not imply safety. Apply the recommended fix and use O3 Security to monitor your exposure.

Description

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.
