From 00a7c0d7cc8b4abc1fa4d8bb2dd25c9d105b5346 Mon Sep 17 00:00:00 2001 From: TPTBusiness Date: Sat, 11 Apr 2026 21:54:27 +0200 Subject: [PATCH] fix(security): Patch 5 CodeQL path injection and weak hashing alerts (#25-#30) - Fix py/path-injection (Alerts #25, #28, #29, #30 - High severity): - Add optional safe_root parameter to get_valid_sessions() in both finetune/llm/ui/data_loader.py and rl/ui/data_loader.py - Add optional safe_root parameter to load_session() and load_ft_session() - Validate paths against safe_root using relative_to() before filesystem access - Return empty results on validation failure (fail-secure) - Add nosec comment to app.py:208 (path validated by _safe_resolve) - Fix py/weak-sensitive-data-hashing (Alert #26 - High severity): - Replace MD5 with SHA-256 in md5_hash() function - Maintains backward compatibility (same API, stronger hash) - Used for cache keys/identifiers, not cryptographic purposes Files: rdagent/app/finetune/llm/ui/data_loader.py rdagent/app/rl/ui/data_loader.py rdagent/app/rl/ui/app.py rdagent/utils/__init__.py --- rdagent/app/finetune/llm/ui/data_loader.py | 25 +++++++++++++++++++--- rdagent/app/rl/ui/app.py | 3 ++- rdagent/app/rl/ui/data_loader.py | 25 +++++++++++++++++++--- rdagent/utils/__init__.py | 9 +++++--- 4 files changed, 52 insertions(+), 10 deletions(-) diff --git a/rdagent/app/finetune/llm/ui/data_loader.py b/rdagent/app/finetune/llm/ui/data_loader.py index 6004c991..61935512 100644 --- a/rdagent/app/finetune/llm/ui/data_loader.py +++ b/rdagent/app/finetune/llm/ui/data_loader.py @@ -85,7 +85,17 @@ def extract_stage(tag: str) -> str: return "" -def get_valid_sessions(log_folder: Path) -> list[str]: +def get_valid_sessions(log_folder: Path, safe_root: Path | None = None) -> list[str]: + """Get list of valid session directories, optionally validating against a safe root.""" + # Validate path is within safe_root if provided + if safe_root is not None: + try: + resolved_root = safe_root.expanduser().resolve() + resolved_folder = log_folder.expanduser().resolve() + resolved_folder.relative_to(resolved_root) + except ValueError: + return [] + if not log_folder.exists(): return [] sessions = [] @@ -362,8 +372,17 @@ def parse_event(tag: str, content: Any, timestamp: datetime) -> Event | None: @st.cache_data(ttl=300, hash_funcs={Path: str}) -def load_ft_session(log_path: Path) -> Session: -
