From 2fe7163c89aac312939d44f7ed1ae6d4de4dbc81 Mon Sep 17 00:00:00 2001 From: Cal Corum Date: Sun, 8 Mar 2026 16:04:25 -0500 Subject: [PATCH] fix: resolve MEDIUM-severity issues from code review Prompt injection mitigation: - Wrap user question in XML tags in LLM prompt - Add system prompt instruction to treat tagged content as untrusted Docker security: - Bind ChromaDB and API ports to localhost only (127.0.0.1) - Remove redundant DB init command from api service (lifespan handles it) - Remove deprecated version field and unused volume definitions - Add API_SECRET env var to api and discord-bot services Gitea labels fix: - Remove string labels from API payload (Gitea expects integer IDs) - Include label names as text in issue body instead Conversation cleanup: - Add periodic background task in lifespan (every 5 minutes) - Cleans up conversations older than CONVERSATION_TTL (default 30 min) - Graceful cancellation on shutdown Co-Authored-By: Claude Opus 4.6 --- adapters/outbound/gitea_issues.py | 5 ++-- adapters/outbound/openrouter.py | 3 ++- config/container.py | 22 ++++++++++++++++- docker-compose.yml | 21 ++++------------ tests/adapters/test_gitea_issues.py | 37 ++++++++++++++++------------- 5 files changed, 51 insertions(+), 37 deletions(-) diff --git a/adapters/outbound/gitea_issues.py b/adapters/outbound/gitea_issues.py index e37726e..9b9cac9 100644 --- a/adapters/outbound/gitea_issues.py +++ b/adapters/outbound/gitea_issues.py @@ -15,7 +15,7 @@ from domain.ports import IssueTracker logger = logging.getLogger(__name__) -_LABELS: list[str] = ["rules-gap", "ai-generated", "needs-review"] +_LABEL_TAGS: list[str] = ["rules-gap", "ai-generated", "needs-review"] _TITLE_MAX_QUESTION_LEN = 80 @@ -90,7 +90,6 @@ class GiteaIssueTracker(IssueTracker): payload: dict = { "title": title, "body": body, - "labels": _LABELS, } url = f"{self._base_url}/repos/{self._owner}/{self._repo}/issues" @@ -149,6 +148,7 @@ class GiteaIssueTracker(IssueTracker): input cannot alter the issue structure.
