From 6174836b7fefa11e9faf21d3a00504bf2f938010 Mon Sep 17 00:00:00 2001 From: Claude Date: Mon, 6 Apr 2026 11:03:11 +0000 Subject: [PATCH] Fix critical and high-severity issues from project audit Security: - Fix path traversal via backslash bypass in sync validate_sync_path() - Replace silent HTTP client fallback with proper error propagation - Add 64KB YAML frontmatter size limit to prevent DoS via crafted files Data integrity: - Reorder delete operations: update metadata before removing files to prevent orphaned metadata entries on crash - Fix task deduplication to use file mtime as tiebreaker when versions are equal, preventing non-deterministic data loss - Add rollback on conflict recovery failure (remove orphaned duplicate files when metadata update fails) - Clean up temp files on atomic write rename failure - Add file-based sync lock to prevent concurrent sync operations - Use saturating_add for task version to prevent overflow Error handling: - Surface move_task rollback failures as structured errors instead of silent warnings - Log WebDAV parallel request failures instead of silently swallowing - Emit watcher-error events to frontend instead of only printing to stderr Frontend: - Fix focus listener leak in auto-sync (clean up if stopAutoSync called while promise pending) - Add prefers-reduced-motion CSS media query for accessibility - Add ARIA labels, roles, and keyboard handlers to TaskItem, BottomSheet, and ConfirmDialog components - Replace BottomSheet children: any with Snippet type https://claude.ai/code/session_01AJoK28N4vqLqzskq6ybGri --- apps/tauri/src-tauri/src/lib.rs | 21 +++- apps/tauri/src/app.css | 13 +++ .../src/lib/components/BottomSheet.svelte | 9 +- .../src/lib/components/ConfirmDialog.svelte | 4 +- apps/tauri/src/lib/components/TaskItem.svelte | 11 ++- apps/tauri/src/lib/stores/app.svelte.ts | 11 ++- crates/onyx-core/src/repository.rs | 7 +- crates/onyx-core/src/storage.rs | 48 +++++++--- crates/onyx-core/src/sync.rs | 96 +++++++++++++++---- crates/onyx-core/src/webdav.rs | 23 ++--- 10 files changed, 190 insertions(+), 53 deletions(-) diff --git a/apps/tauri/src-tauri/src/lib.rs b/apps/tauri/src-tauri/src/lib.rs index b40718c..314a8d6 100644 --- a/apps/tauri/src-tauri/src/lib.rs +++ b/apps/tauri/src-tauri/src/lib.rs @@ -111,6 +111,8 @@ fn mute_watcher(_state: &mut AppState) { fn mute_watcher(_state: &mut AppState) {} /// Helper: get or open a TaskRepository for the current workspace. +/// Safe against double-init because it runs under the AppState Mutex and uses +/// get_or_insert to atomically check-and-set. fn ensure_repo(state: &mut AppState) -> Result<(), String> { if state.repo.is_some() { return Ok(());
