From fab4545454f3b9a727ea14fffded207935a88e44 Mon Sep 17 00:00:00 2001 From: Tom Maiaroto Date: Thu, 22 Oct 2026 18:59:38 -0700 Subject: [PATCH 1/3] fix: close the three residual findings from the 2026-10-20 security audit MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Completes the audit follow-up left open after #50 and #51: - csync.Map no longer exposes a value-receiver JSONSchemaAlias that copies its own mutex (go vet copylocks). The config JSON schema is now produced by a Reflector.Mapper in the schema command, which also fixes the slash-containing $defs key that broke JSON Pointer $ref resolution for provider entries. - NewFetchTool/NewDownloadTool accept the config so their no-client fallback builds a fail-closed secured client that honors allow_raw_ips and ip_allow_list instead of silently ignoring them. - Security docs no longer point at stale internal/ paths, and the startup symlink-resolution section describes what the code actually does (resolution happens after config parsing, before store construction). ஃ Generated with Phosphor Assisted-by: Phosphor:CYBER-FROST-3.8-EXL3-SAGE-3.87bpw --- docs/security/ENVIRONMENT_HARDENING.md | 14 ++--- .../SECURITY_VALIDATION_TEST_SUITE.md | 32 +++++------ docs/security/WORKSPACE_HARDENING.md | 55 ++++++++++--------- internal/cmd/schema.go | 27 ++++++++- internal/cmd/schema_test.go | 5 +- pkg/agent/common_test.go | 4 +- pkg/agent/coordinator.go | 4 +- pkg/agent/tools/download.go | 5 +- pkg/agent/tools/fetch.go | 5 +- pkg/agent/tools/url_secret_guard_test.go | 10 ++-- pkg/agent/tools/workspace_hardening_test.go | 2 +- pkg/csync/maps.go | 8 --- .../content/security/ENVIRONMENT_HARDENING.md | 14 ++--- .../content/security/WORKSPACE_HARDENING.md | 55 ++++++++++--------- 14 files changed, 133 insertions(+), 107 deletions(-) diff --git a/docs/security/ENVIRONMENT_HARDENING.md b/docs/security/ENVIRONMENT_HARDENING.md index 9d4f655..f92c425 100644 --- a/docs/security/ENVIRONMENT_HARDENING.md +++ b/docs/security/ENVIRONMENT_HARDENING.md @@ -39,13 +39,13 @@ but absent from the process environment entirely. └───────────────────────────────────────────────────────────┘ │ ▼ - internal/shell/shell.go → NewShell() + pkg/shell/shell.go → NewShell() (the single enforcement point for all shell surfaces) ``` ## Layer 2: Environment Filtering -**Location:** `internal/shell/env.go`, `internal/shell/shell.go` +**Location:** `pkg/shell/env.go`, `pkg/shell/shell.go` When `NewShell` is called without an explicit `Env` slice, the process environment (`os.Environ()`) is filtered through an allowlist.

Add a newConfigSchema() helper that reflects ProviderConfig with ExpandedStruct and promotes its nested definitions to the root, and point both the schema command and the schema tests at it so they validate the exact document the command emits. Also quote the -run regex in the hardening docs so the documented test command is copy-pasteable, and clarify that the workspace config merge happens after ConfigStore construction. ஃ Generated with Phosphor Assisted-by: Phosphor:CYBER-FROST-3.8-EXL3-SAGE-3.87bpw --- docs/security/ENVIRONMENT_HARDENING.md | 2 +- docs/security/WORKSPACE_HARDENING.md | 8 ++++--- internal/cmd/schema.go | 24 ++++++++++++++++++- internal/cmd/schema_test.go | 9 ++++--- .../content/security/ENVIRONMENT_HARDENING.md | 2 +- .../content/security/WORKSPACE_HARDENING.md | 8 ++++--- 6 files changed, 39 insertions(+), 14 deletions(-) diff --git a/docs/security/ENVIRONMENT_HARDENING.md b/docs/security/ENVIRONMENT_HARDENING.md index f92c425..f9228fa 100644 --- a/docs/security/ENVIRONMENT_HARDENING.md +++ b/docs/security/ENVIRONMENT_HARDENING.md @@ -454,5 +454,5 @@ Comprehensive tests are in `pkg/shell/env_test.go` and Run with: ```bash -go test ./pkg/shell/ ./pkg/agent/tools/ -run TestFilterEnv|TestSafeDefaultEnv|TestPhosphorEnvMarkers|TestNewShell|TestBashTool_ConfigAwareBannedCommands +go test ./pkg/shell/ ./pkg/agent/tools/ -run 'TestFilterEnv|TestSafeDefaultEnv|TestPhosphorEnvMarkers|TestNewShell|TestBashTool_ConfigAwareBannedCommands' ``` diff --git a/docs/security/WORKSPACE_HARDENING.md b/docs/security/WORKSPACE_HARDENING.md index 99a945d..7dc2ad4 100644 --- a/docs/security/WORKSPACE_HARDENING.md +++ b/docs/security/WORKSPACE_HARDENING.md @@ -247,9 +247,11 @@ This is defense-in-depth — it tells the LLM the rules so it is less likely to **Location:** `pkg/config/load.go:63-68` -The workspace root is resolved via `filepath.EvalSymlinks` after the config -files are parsed but before the `ConfigStore` is constructed and providers -are wired, so every consumer of the workspace path sees the resolved target +The workspace root is resolved via `filepath.EvalSymlinks` after the initial +config files are parsed but before the `ConfigStore` is constructed.

The +workspace config is merged afterward (after `ConfigStore` construction, at +the highest priority); either way, resolution happens before the store is +built, so every consumer of the workspace path sees the resolved target and bounds checking cannot be bypassed through symlink traversal. If the workspace doesn't exist on disk (e.g., during tests), the original path is used as-is. From 5234ae621a77d5b74c84ba5475580b6aacb8471d Mon Sep 17 00:00:00 2001 From: Tom Maiaroto Date: Thu, 22 Oct 2026 22:08:30 -0700 Subject: [PATCH 3/3] chore: disable CodeRabbit docstring-coverage check for the Go codebase MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Go has no docstrings; godoc comments enforced by our own linters are the Go idiom, so the Python-centric coverage gate flags every Go diff with a false positive. Verified against the CodeRabbit configuration reference: reviews.pre_merge_checks.docstrings.mode: "off" is the supported toggle. ஃ Generated with Phosphor Assisted-by: Phosphor:CYBER-FROST-3.8-EXL3-SAGE-3.87bpw --- .coderabbit.yaml | 7 +++++++ 1 file changed, 7 insertions(+) diff --git a/.coderabbit.yaml b/.coderabbit.yaml index ed7dcbc..4a8d06d 100644 --- a/.coderabbit.yaml +++ b/.coderabbit.yaml @@ -3,6 +3,13 @@ # quota on generated docs, bot PRs, and per-push incremental re-reviews. reviews: + # Go has no docstrings — godoc comments (enforced by the linters we + # already run) are the Go idiom.
