From 8688579fcf441b27a6eb6309de04fd54b76b7353 Mon Sep 17 00:00:00 2001 From: Harald Roessler Date: Tue, 12 May 2026 07:26:41 +0700 Subject: [PATCH 1/8] security: low-risk hardening pass (10 fixes) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Mechanical fixes from a Bandit/Semgrep + manual-review audit pass. Scope is intentionally narrow: only changes that are clearly correct, behaviour-preserving, and unlikely to break running deploys. 1. [CRITICAL] Constant-time admin-key comparison (15 sites) - app/main.py: 14 endpoints - app/billing.py: 1 endpoint `admin_key != expected` is vulnerable to timing attacks — an attacker can brute-force the key character-by-character by measuring response latency. Replaced with secrets.compare_digest, guarded by truthy checks so the function never sees None. 2. [CRITICAL] Admin bcrypt hashes moved out of source - app/admin_auth.py Three hardcoded bcrypt hashes for lars/harald/bernd are now loaded from MOLTRUST_ADMIN_USERS env var (format: "name:role:$2b$12$...,name:role:$2b$12$...,..."). Missing env var → empty admin set → all login attempts refused (fail-closed). *** BREAKING for any deploy that hasn't set MOLTRUST_ADMIN_USERS. *** Migration: extract the three hashes from git history into your secrets manager, set the env var on the server, redeploy. 3. [CRITICAL] Container no longer runs as root - Dockerfile Added `useradd appuser` + `USER appuser` before CMD. Limits blast radius if uvicorn or a dependency is compromised. 4. [HIGH] MD5 → SHA-256 for dedup keys - agents/moltbook_poster.py:262 (post_hash) - agents/news_scout.py:108 (url_key) MD5 is cryptographically broken. Both uses are non-security (dedup), but switching avoids static-analysis noise. 5. [HIGH] defusedxml for untrusted RSS feeds - agents/news_scout.py + requirements.txt xml.etree.ElementTree.fromstring on attacker-controlled RSS feeds is exposed to XXE / Billion Laughs / DTD bombs. defusedxml is imported with stdlib fallback so the file still parses on hosts without the package installed. 6. [HIGH] CORS wildcard tightened in dev server - app/main_dev.py allow_origins=["*"] → explicit allowlist (localhost + 127.0.0.1 by default; override via MOLTRUST_DEV_CORS_ORIGINS). 7. [HIGH] HTTP timeouts added (7 sites) - agents/x_thread_followup.py, agents/x_wallet_binding.py, scripts/telegram_hn_remind.py, seed_ecosystem.py (×4) requests.{get,post} without timeout can hang indefinitely. Added timeout=15s on every call. 8. [HIGH] URL scheme validation before urllib.request.urlopen - app/main.py (ip enrichment), app/ipfs_publisher.py, agents/poll_payments.py, agents/retention_cleanup.py, monitor/poll_payments.py, scripts/erc8004_scanner.py Without scheme validation, urlopen happily handles file://, ftp://, etc., which under variable-URL conditions can leak local files or SSRF internal services. Added explicit http(s):// guards. 9. [MEDIUM] Swagger UI CDN gets SRI integrity hash - app/main.py Pinned @5 → @5.17.14, added sha384 SRI hash + crossorigin. Hash was computed locally: curl -sL .../swagger-ui-bundle.js | openssl dgst -sha384 -binary | openssl base64 -A 10. [MEDIUM] ip-api.com upgraded to HTTPS - app/main.py (_enrich_ip) Default base URL is now https://ip-api.com (configurable via MOLTRUST_IP_ENRICH_BASE). Plain HTTP would let a MITM inject false geolocation data. EXPLICITLY OUT OF SCOPE (separate PRs / your call) - .env.dilithium (gitignored; local-disk hygiene only) - IP enrichment removal entirely (GDPR/privacy decision) - X-Forwarded-For trust restriction (deployment-topology dependent) - Making NONCE_SECRET, MOLTSTACK_DB_PW, etc. required at startup (migration risk for running deploys) - In-memory session-store cleanup (admin_auth.py SESSIONS dict) - print() → logger across 15+ sites (large mechanical pass) - subprocess → web3 / ssl module refactors (touches core paths) - Plaintext key fallback in app/crypto/kms_signer.py (design call) VERIFICATION Python AST parse — all 15 touched .py files compile cleanly. No tests modified; existing CI should continue to pass.

The host portion of any external `did:web:*` identifier is fully attacker-controlled — it's the path segment of the request. The function previously fed it straight into `httpx.AsyncClient.get(...)` without validating that the resolved address is publicly routable. WHAT AN ATTACKER COULD DO did:web:169.254.169.254 → read AWS/GCP/Azure metadata (incl. IAM creds) did:web:metadata.google.internal → same, by hostname did:web:127.0.0.1%3A5984 → hit local CouchDB / Redis / debug ports on the API host did:web:10.0.0.5%3A8080 → probe internal services in private network did:web:[::1] → IPv6 loopback variant The response body is returned to the caller via `resp.json()` (or leaks via the "didDocument is not valid JSON" error message), so the exfiltration channel is direct, not just a side-channel. FIX New `_assert_public_host(host)` runs before the httpx GET. It: - Rejects banned hostnames (localhost, metadata.google.internal, instance-data.ec2.internal, etc.) - Strips port and IPv6 brackets, parses the host - If the host is a literal IP, rejects when it falls in any of: 0.0.0.0/8, 10.0.0.0/8, 100.64.0.0/10 (CGNAT), 127.0.0.0/8, 169.254.0.0/16 (link-local incl. cloud metadata), 172.16.0.0/12, 192.0.0.0/24, 192.168.0.0/16, 198.18.0.0/15 (benchmark), 224.0.0.0/4 (multicast), 240.0.0.0/4 (reserved), ::1/128, fc00::/7, fe80::/10, ff00::/8, ::ffff:0:0/96 (IPv4-mapped IPv6) - If the host is a name, resolves it via getaddrinfo (wrapped in asyncio.to_thread) and refuses if ANY returned address falls in a banned range. LIMITS - DNS rebinding (host resolves public at check time, private at fetch time) is not closed by this patch. Closing it requires pinning the IP and passing it via httpx's transport; deferred as a defense-in-depth follow-up. - did:web spec was designed for public hostnames anyway. Any legitimate consumer of the registry uses public hosts; this change should not break any real workflow. `did:web:api.moltrust.ch` still resolves normally.

After running CodeQL default-setup on the fork, 17 additional findings surfaced. Triage outcome: Already closed by earlier commits this PR: 1 (SSRF) False positives (dismissed via CodeQL UI): 4 Real findings fixed in this commit: 5 Stack-trace-exposure (deferred to design): 7 FIXES IN THIS COMMIT #1 [LOG SANITISATION] credit_middleware exception swallows DB password - app/main.py (logger.error in credit_middleware) `logger.error("…: %s", caller_did, e)` — the raw exception `e` can be an asyncpg ConnectionError whose repr() includes the Postgres connection string (with the password). Log only `type(e).__name__` instead. #2 [DEFENSIVE URL ENCODING] /join?ref= referrer parameter - app/main.py /join handler The redirect target is HARDCODED to https://moltrust.ch — the host is not user-controlled. But `f"https://moltrust.ch?ref={ref}"` interpolates `ref` raw, and a payload like `ref="x&malparam=…"` could corrupt the query string. Use `urllib.parse.quote(ref)` to percent-encode the value before interpolation. #3 [STDOUT TOKEN LEAK] telegram_hn_remind print(r.text) - scripts/telegram_hn_remind.py `print(f'Status: {r.status_code}, Response: {r.text}')` — if Telegram error responses ever echo the request URL (which contains the bot token in the path), the body lands in stdout / CI scrollback. Print only the status code. #4 [ReDoS] mpp authorization header regex - packages/mpp/index.js `auth.match(/^(?:Payment|MPP)\s+(.+)$/i)` on an unbounded header is polynomial-quadratic. This package is published to npm, so consumer servers carry the risk. Cap header at 8 KiB and use bounded `\s{1,8}` with a non-greedy first char. #5 [ReDoS] moltrust-openclaw-v2 base URL trim - moltrust-openclaw-v2/src/client.ts `.replace(/\/+$/, "")` is polynomial on pathological inputs. Replace with a `while (str.endsWith("/")) str = str.slice(0, -1)` loop, which is linear. DISMISSED AS FALSE POSITIVES (no code change) #14 py/clear-text-logging-sensitive-data at SPIFFE bind log Logs spiffe_uri, did, caller_did — none are passwords. CodeQL misfires on the "did" → "id" → "password" name-similarity heuristic. #13, #12 py/clear-text-logging-sensitive-data in scripts/threadwatch.py Telegram bot token flows into the request URL but never into a logger or print() call — only to requests.post (which doesn't log URLs by default). #16 py/weak-sensitive-data-hashing in _reg_tracker This is in-memory rate-limit bucket-key derivation, not password storage. bcrypt/argon2 would be wrong here (slow + salted breaks the lookup). SHA-256 of the full API key is the correct primitive for an O(1) tracker. EXPLICITLY DEFERRED (7 stack-trace-exposure findings) Multiple endpoints currently return `{"error": str(e)[:100]}` to callers. CodeQL flags these as info disclosure. Fixing them means changing the API contract — clients that parse the `error` field would break. This is a design call for the maintainer; deferring to a separate PR + discussion rather than including in this hardening pass. VERIFICATION Python 3.12 AST parse — app/main.py + scripts/telegram_hn_remind.py compile cleanly. `node -c packages/mpp/index.js` clean. The TS file change is a syntactically-trivial loop, not type-impacting.
