External audit (@tg12, May 18) found that backend/services/updater.py silently skipped all SHA-256 integrity verification whenever the MESH_UPDATE_SHA256 env var was unset — which is the default. Nothing in any install doc tells operators to set it, so practically every deployment was running the auto-updater with zero integrity check. That made GitHub release pipeline compromise a single-step path to arbitrary code execution on every node that auto-updates. Investigation surfaced a deeper bug too: the updater downloads zipball_url (GitHub's auto-generated source archive) but the maintainer's release process publishes SHA256SUMS.txt for a separate named asset (ShadowBroker_v*.zip). So even if MESH_UPDATE_SHA256 WERE set, operators had no published digest to compare against — the file they were downloading wasn't the file the maintainer had signed. This PR fixes both issues with the same multi-source verification chain we shipped for the Tor bundle in PR #261: backend/services/updater.py _download_release() now prefers a maintainer-signed release asset matching ShadowBroker_v*.zip over zipball_url. Captures the SHA256SUMS.txt asset URL when present. _validate_zip_hash() rewritten as a four-source chain: 1. MESH_UPDATE_SHA256 env var (operator override, preserved) 2. SHA256SUMS.txt asset published with the release (primary — the maintainer's release process already publishes this) 3. Baked-in backend/data/release_digests.json (second line of defense for releases that lack the SHA256SUMS asset, or when the asset can't be fetched at update time) 4. HTTPS-only fallback with a loud warning (preserves the auto- update flow during transient outages) Mismatch from any source that DID respond is fatal — the update is refused and the existing install keeps running. Only the "no source reachable at all" case falls back to HTTPS-only. _fetch_sha256sums() new — fetches and parses a standard SHA256SUMS.txt asset. Handles both "<digest> <name>" and binary- marker "<digest> *<name>" formats. Tolerant to comments, blank lines, and malformed entries. backend/data/release_digests.json (new) Baked-in digest list keyed by release tag. Seeded with the v0.9.79 entries copied from the published SHA256SUMS.txt: ShadowBroker_v0.9.79.zip = f6877c1d6661... ShadowBroker_0.9.79_x64-setup.exe = f7b676ada45c... ShadowBroker_0.9.79_x64_en-US.msi = e0713c3cdda1... Whitelisted in .gitignore alongside the other static reference data files (kiwisdr_directory.json, tor_bundle_digests.json, aisstream_spki_pins.json). backend/tests/test_update_integrity_chain.py (new, 16 tests) - Each source matches → success, identifies which source verified - Each source mismatches → RuntimeError "mismatch" - No source reachable → https-only fallback with loud warning - Env override beats all other sources (preserved precedence) - SHA256SUMS.txt parser handles standard, binary-marker, comments, and network-failure cases Validation: pytest backend/tests/test_update_integrity_chain.py → 16 passed pytest (all 15 security test files together) → 105 passed UX impact: zero. Normal auto-update flow is unchanged for legitimate releases (path 2 catches everything because the release publishes SHA256SUMS.txt). Transient network failures during update gracefully fall through to path 3 then path 4 — no operator intervention needed. The only user-visible behavior change is in the compromised-release case, where the update is now refused instead of silently applied.
