# GHSA: Unauthenticated Remote Code Execution via `found-action` in Dalfox Server Mode ## Summary When dalfox is started in REST API server mode (`dalfox server`), the server binds to `0.0.0.0:6664` by default and requires no API key unless the operator explicitly passes `--api-key`. Because `model.Options` — including `FoundAction` and `FoundActionShell` — is deserialized directly from attacker-supplied JSON in `POST /scan`, and because `dalfox.Initialize` explicitly propagates those two fields into the final scan options without stripping them, any unauthenticated caller who can reach the server port can supply an arbitrary shell command that the dalfox process will execute on the host whenever a scan finding is triggered. ## Severity **Critical** (CVSS 3.1: 10.0) `CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:H` - **Attack Vector:** Network — the server binds to `0.0.0.0` by default; reachable by any network peer. - **Attack Complexity:** Low — the attacker fully controls the scanned URL and can trivially host a one-line reflective server to guarantee a finding is triggered. - **Privileges Required:** None — no API key is enforced in the default configuration. - **User Intera
03 / Response
What to do next
- investigate
Identify the exact component and deployed version, examine the linked publisher’s conditions, and retain evidence of any mitigation.
Confirm current vendor support, compatibility and deployment evidence. This report has not tested a fix in your system. GitHub Advisory Database
A fixed release is not deployment evidence.
Check current vendor support and compatibility. After making a change, verify the deployed build and relevant runtime conditions. Keep the evidence, owner and time. An updated lockfile alone does not prove what is running.
