From e4f5519554a40812889db22a293bcceb99619a21 Mon Sep 17 00:00:00 2001 From: Rolando Santamaria Maso Date: Sat, 18 Jul 2026 15:34:46 +0200 Subject: [PATCH] fix: record @-refs, --ctx, and Web-UI attachments in audit log (M-9) Makes the audit ingest recorder and divergence heuristic aware of @-references, --ctx files, and Web-UI attachments. Changes: - cmd/odek/refs.go: enrichTask now accepts a context and uses it for wrapUntrusted/recordIngest. - cmd/odek/main.go: attach the audit recorder before enrichment in odek run --session and odek continue; pass the original prompt to recordTurnAudit so injected resources are not treated as user-mentioned. - cmd/odek/serve.go: attach the audit recorder before @-ref/attachment resolution; recordTurnAudit receives the original prompt. - cmd/odek/audit.go: scan user messages for untrusted wrappers and use the original userText for the divergence heuristic. - Added regression tests for recorder attachment and user-message wrapper handling. - Updated docs/SECURITY.md and AGENTS.md. --- AGENTS.md | 1 + cmd/odek/audit.go | 19 ++ cmd/odek/audit_test.go | 117 +++++++ cmd/odek/main.go | 287 ++++++++++-------- .../next_security_vulnerabilities_test.go | 4 +- cmd/odek/refs.go | 10 +- cmd/odek/refs_test.go | 71 ++++- cmd/odek/repl.go | 30 +- cmd/odek/serve.go | 73 ++--- docs/SECURITY.md | 16 + 10 files changed, 447 insertions(+), 181 deletions(-) diff --git a/AGENTS.md b/AGENTS.md index 2edf48bb..ad9194be 100644 --- a/AGENTS.md +++ b/AGENTS.md @@ -180,6 +180,7 @@ Layered prompt-injection / approval-fatigue defenses. Full reference: [docs/SECU - **Sub-agent trust defaults + delegate_tasks gate** (`cmd/odek/subagent.go`, `internal/loop/loop.go`) — a missing `trust_level` in `delegate_tasks` defaults to `untrusted`; `delegate_tasks` itself is classified as `system_write` so it requires explicit approval before spawning child processes. - **Memory add/replace pipe-to-shell filter** (`internal/memory/memory.go`) — `AddFact` and `ReplaceFact` now run `FactLooksUnsafe` in addition to the general guard scan, blocking agent-driven planting of download-and-execute facts. - **Skill learn-loop provenance propagation** (`internal/skills/learnloop.go`) — conversation-extracted suggestions and LLM-enhanced suggestions both retain the session's `SkillProvenance`, so tainted sessions cannot produce clean-looking auto-saved skills. +- **Audit ingest recording for @-refs, `--ctx`, and Web-UI attachments** (`cmd/odek/refs.go`, `cmd/odek/serve.go`, `cmd/odek/audit.go`) — the per-session ingest recorder is attached before `@`-reference/`--ctx`/attachment resolution, `recordTurnAudit` scans `user` messages for untrusted wrappers in addition to `tool` messages, and the divergence heuristic compares agent actions against the original pre-enrichment prompt so attacker-injected resources are not treated as user-mentioned. - **Session ID entropy + session-scoped auth tokens** (`internal/session/session.go`, `cmd/odek/serve.go`) — session IDs now carry 128 bits of randomness (16 bytes / 32 hex chars); each session stores a 256-bit `AuthToken` required by `GET/DELETE/POST /api/sessions/`, `POST /api/cancel`, and WebSocket session-resume messages via `X-Session-Token` header, `session_token` cookie, or `auth_token` WS field. Per-IP rate limiting (60/min) on session lookups adds a brute-force backstop. - **Skill/episode untrusted wrapper** (`internal/loop/loop.go` + `odek.go`) — skill context and retrieved session-episode context are passed through the caller-provided untrusted wrapper (the same nonce'd `` boundary used for tool output) before being injected into the model's system context. This prevents a compromised or tainted skill/episode from being treated as trusted system instructions. - **`env` / `printenv` environment-dump gate** (`internal/danger/classifier.go`) — bare `env` and `printenv` invocations are classified as `system_write` because they can leak process-environment secrets that the redaction scanner does not recognise. `env VAR=value ` still classifies `` normally. diff --git a/cmd/odek/audit.go b/cmd/odek/audit.go index 65730d08..140746f4 100644 --- a/cmd/odek/audit.go +++ b/cmd/odek/audit.go @@ -21,6 +21,11 @@ import ( // user's message, or (b) were introduced by the untrusted content itself. // This is exactly the footprint of a successful prompt injection that // steered the agent toward an attacker-chosen resource. +// +// userText must be the original user prompt *before* @-reference, +// --ctx, or attachment expansion.
