# CVE-2026-41492: Dgraph: Unauthenticated Admin Token Disclosure Leading to Authentication Bypass via /debug/vars

**Signal:** Critical and remotely reachable. No known exploitation yet, but it is network-reachable without credentials. (Computed from CISA KEV, EPSS and CVSS; not an editorial verdict.)

## Should you act?

- Not in CISA KEV , but CISA’s SSVC assessment records a public proof-of-concept, so attack code exists.
- EPSS 2.5% , percentile 84: FIRST’s model estimates a 2.5% chance of exploitation activity in the next 30 days, higher than 84% of all scored CVEs (elevated). EPSS is a probability, not a verdict.
- Remotely reachable with no login and no user interaction. If the vulnerable service is exposed to the internet, prioritize it.
- Only applies if your dependency tree includes github.com/dgraph-io/dgraph/v25 (Go) < 25.3.3, fixed in 25.3.3 ; github.com/dgraph-io/dgraph/v24 (Go) <= 24.1.8, no fixed version listed ; github.com/dgraph-io/dgraph (Go) <= 1.2.8, no fixed version listed . Check your lockfile, including transitive dependencies.

## What it is

Dgraph is an open source distributed GraphQL database. Prior to 25.3.3, Dgraphl exposes the process command line through the unauthenticated /debug/vars endpoint on Alpha. Because the admin token is commonly supplied via the --security "token=..." startup flag, an unauthenticated attacker can retrieve that token and replay it in the X-Dgraph-AuthToken header to access admin-only endpoints. This is a variant of the previously fixed /debug/pprof/cmdline issue, but the current fix is incomplete because it blocks only /debug/pprof/cmdline and still serves http.DefaultServeMux, which includes expvar's /debug/vars handler. This vulnerability is fixed in 25.3.3.

## Affected packages

- Go `github.com/dgraph-io/dgraph/v25` < 25.3.3 → fixed: 25.3.3
- Go `github.com/dgraph-io/dgraph/v24` <= 24.1.8 → fixed: none listed
- Go `github.com/dgraph-io/dgraph` <= 1.2.8 → fixed: none listed

## Affected products (CVE record)

- dgraph-io dgraph: < 25.3.3

## Severity

- GitHub_M CVSS 3.1: 9.8 `CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H`
- GitHub CVSS 3.1: 9.8 `CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H`

## Exploitation

- CISA KEV: not listed (no confirmed in-the-wild exploitation known to CISA).
- CISA SSVC assessment: exploitation poc , automatable yes , technical impact total .
- FIRST EPSS (model of 2026-10-21): 2.46% probability of exploitation activity in the next 30 days; percentile 84.
