From 7bf4a8d5e024090a93034adbc53a4405d9dc7b55 Mon Sep 17 00:00:00 2001 From: Lakshman Patel Date: Tue, 15 Sep 2026 05:25:28 +0530 Subject: [PATCH 1/4] fix(security,concurrency,arch): complete the hardening pass Security: - validatePathAllowed now fails closed without a ToolContext; tests attach a permissive test context. - Delete the dead, bypassable BoundaryChecker (no production callers). - Wrap MCP/remote tool output as untrusted external content. - Bound HTTP clients in stt/media; safewrite uses crypto/rand + O_EXCL; hooks URL validation now actually rejects loopback; plugin index reads are capped. Concurrency: - jobs: snapshot cancel status under lock; guard nil Done. - git context, spec tools, watcher: bounded exec timeouts. - planning prompt: context-aware prompt + ctx timeout. - watcher: bounded fireChange workers. - filewatcher/cron: idempotent Stop (no double-close panic). - event bus RunWaterfall: snapshot handlers under lock. - AutoCommit errors logged; AssertWritable returns an error; SessionPreparations load/wait honor a context. Architecture: - Move IsSensitivePath/ResolvePath into internal/pathsafe; drop config->tool. - Consolidate byte-unsafe truncate copies onto textutil (rune-safe). - Delete dead types.ChatClient and the dead markdown_renderer. --- cmd/markdown_renderer.go | 834 ------------------ cmd/markdown_test.go | 620 ------------- cmd/watch.go | 25 +- internal/config/developer_path.go | 4 +- internal/engine/errs/error_recovery.go | 10 +- internal/engine/event_bus.go | 39 +- internal/engine/external_content.go | 29 +- internal/engine/external_content_test.go | 42 + internal/engine/git/git_context.go | 6 +- internal/engine/io/cron_scheduler.go | 18 +- internal/engine/io/filewatcher.go | 11 +- internal/engine/planning/action_required.go | 27 +- internal/engine/stream_helpers.go | 6 +- internal/engine/trajectory.go | 6 +- internal/feature/eval/benchmark.go | 10 +- internal/hooks/hooks_extra2_test.go | 18 +- internal/hooks/http_hooks.go | 27 +- internal/jobs/jobs.go | 34 +- internal/multiagent/worker.go | 6 +- internal/pathsafe/pathsafe.go | 161 ++++ internal/permissions/boundary.go | 605 ------------- .../permissions/boundary_security_test.go | 40 -
