From 789bf91eedc70162dcdb6aa0ec3d4b31c9bfbfca Mon Sep 17 00:00:00 2001 From: Owen Rummage Date: Sun, 23 Aug 2026 09:18:17 -0500 Subject: [PATCH] Complete Phase 4: security hardening, player/playlist/admin UI, docs MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Security: - New internal/netguard package: podcast feed/enclosure fetching now refuses to dial non-public IPs (loopback/RFC1918/link-local/cloud metadata/CGNAT), validated per-connection including across redirects, closing an SSRF gap where a malicious or compromised feed URL could probe the server's internal network. Configurable via VIBESONIC_PODCASTS_ALLOW_PRIVATE_NETWORKS for intentional LAN feeds. - Podcast episode downloads capped at 4GB (was unbounded, disk-exhaustion risk) - Cover art decoding now rejects images above a 40-megapixel budget before full decode (decompression-bomb guard) - HTTP server sets ReadHeaderTimeout (slowloris hardening) - Admin folder-scan redirect now validated as same-site instead of trusting the raw Referer header (open-redirect fix) - Legacy Subsonic token/salt auth now uses a constant-time comparison Web UI completion: - Persistent player: shuffle and repeat (off/all/one) controls, wired into queue advance/prev logic and persisted like other player state - Admin user-permissions form: adminRole toggle (with a guard against demoting the last remaining admin) and per-user music-folder access checkboxes, backed by existing schema/enforcement that was previously unreachable from the UI - Playlist M3U8 import/export Docs: added docs/client-compatibility.md (honest tracking template — no client testing has been performed), docs/deployment.md, docs/security.md, docs/backup.md; refreshed README and cross-links; added a footnote in docs/subsonic-compatibility.md distinguishing spec-standard from VibeSonic-original OpenSubsonic extensions. Also added Go fuzz tests for the external-auth CIDR/IP parser and the LRC lyrics parser.
