csurf has been deprecated since 2022 and pins an old cookie release with a known advisory; npm's only fix is a downgrade (issue #1634, item 2). csrf-csrf v4 implements the same double-submit-cookie pattern with an HMAC-signed, session-bound token keyed on the existing boot secret (common.secret_key). The frontend contract is unchanged: the token still arrives via the XSRF-TOKEN cookie/header and is echoed as x-xsrf-token (all token sources csurf accepted are still read), the signed cookie keeps the _csrf name (now httpOnly, secure:false to match the session cookie on plain-HTTP deployments), doubleCsrfProtection attaches req.csrfToken so app.ts keeps working, and the error code is EBADCSRFTOKEN - already handled in app.ts. The websocket upgrade check in authCheck.ts now routes through the shared middleware; upgrade requests are GETs, so its pass-through semantics are unchanged. One fix this surfaced: app.ts called req.csrfToken() twice (cookie and header). Under csurf every token validated against a stable secret; under csrf-csrf each first-visit call mints a new token, desyncing the XSRF-TOKEN cookie from the _csrf cookie it must equal. The token is now generated once per request. Tokens are session-bound, so a token stolen from one session no longer validates in another - a check csurf's cookie mode did not perform. Production npm audit drops from 6 low findings to 4, all in the crypto-browserify/elliptic chain tracked in #1634. Verified against the docker regtest fixture: both API suites (43 checks across LND, CLN and Eclair) plus a dedicated CSRF battery - valid-token auth, missing token 403, garbage token 403, cross-session replay 403, token stability across requests, the XSRF-TOKEN response header for Quickpay, and the websocket handshake. Lint and build are clean. |
