* refactor(backend): sanitize user input before logging to close CRLF injection
Adds a small sanitizeForLog helper that strips CR, LF, tab, and ASCII
control characters (0x00-0x1F, 0x7F) from a value before it is embedded
in a console.log/warn/error/debug call. Wraps every call site where a
user-controlled value (req.params, req.body, req.query, or a value
derived from them) flows into a log message.
Closes the bulk of the open CodeQL alerts in this family:
- 96 js/log-injection
- 28 js/tainted-format-string
The helper is in backend/src/utils/safeLog.ts. Routes still pre-validate
input at the request boundary; this is the second line of defense and
gives static analyzers a sanitizer they can trace through. JSON
responses, Docker filter labels, and other non-log call sites are
intentionally left unwrapped.
* refactor(backend): printf-style format strings for tainted-log call sites
CodeQL's js/tainted-format-string rule flags template literals in the first
arg of console.X when any interpolated value is user-controlled, regardless
of whether each value is sanitized inline. The canonical mitigation is to
use a static format string and pass values as positional args.
Converts the 28 flagged template literals to printf-style ("%s") format
strings, with sanitizeForLog applied to each positional arg. Also fills in
the log-injection wraps on 9 sites where a user-controlled value was
missed in the first sweep (agents, fleet, gitSources, imageUpdates,
GitSourceService).
No behavior change at runtime. Node's util.format substitutes %s tokens
identically to template-literal interpolation.
* fix(backend): wrap nodeId/snapshotId in fleet restore debug log
CodeQL flagged the unwrapped numeric args even though they cannot
contain control chars in practice. Apply the sanitizer for taint-flow
recognition.
Second slice of Phase 4. Pulls the three auth-family route groups out of
index.ts into focused routers. All handlers move verbatim; index.ts drops
~845 lines.
New route files:
- routes/auth.ts: /api/auth core (status, setup, login, password, logout,
check, generate-node-token)
- routes/mfa.ts: /api/auth/login/mfa + full /api/auth/mfa/* surface
(status, enroll start/confirm, disable, backup-codes/regenerate,
sso-bypass)
- routes/sso.ts: /api/auth/sso/{providers,ldap,oidc/:provider/authorize,
oidc/:provider/callback} + getSSOBaseUrl helper. Module-load calls
SSOService.getInstance().seedFromEnv() so env-seeded providers are
available on the first request.
Shared lifts:
- helpers/constants.ts: MFA_REPLAY_TTL_MS + MFA_REPLAY_PURGE_INTERVAL_MS
(used by mfa.ts and the startup purge timer in index.ts) and
BCRYPT_SALT_ROUNDS (shared between setup and password-change handlers).
- middleware/auth.ts: new reissueSessionAfterTokenBump(req, res, userId)
helper collapses three copies of "bump → fetch user → re-sign cookie"
across auth.ts (password change) and mfa.ts (enrol confirm, disable).
Code review fixes:
- File-local requireEnrolledMfaUser helper in mfa.ts eliminates four
copies of "auth check + rejectApiTokenScope + load enrolled MFA" with
near-identical shape.
- Applied BCRYPT_SALT_ROUNDS to auth.ts setup + password handlers.
Mount order in index.ts: authRouter / mfaRouter / ssoRouter sit before
authGate because login / setup / SSO-callback are public; handlers that
need auth use authMiddleware directly on the route.
