This looks like a sensible hardening step with minimal functional impact. Rejecting symlinked repository directories early in _validate_repo_path_for_linking strengthens the trust boundary around repo path handling and reduces the risk of unexpected path resolution outside the intended workspace. I also like that this check happens before the filesystem existence validation, since it makes the sanitization flow more explicit and easier to reason about from both a security and static-analysis perspective. Assuming symlinked repos are not an intended supported use case, this seems like a clean way to tighten validation without changing normal behavior for valid linked repositories.

Potential fix for https://github.com/ArshVermaGit/SentinelOps-Autonomous-DevOps-AI/security/code-scanning/27
General fix: ensure user-provided repo paths are validated with a dedicated “safe canonical path” gate before any filesystem sink use, and enforce that the resulting canonical path is strictly inside the allowed root and not a symlinked repo directory.
Best single fix here: strengthen
_validate_repo_path_for_linkinginsentinelops-backend/app/services/local_git_service.pyby rejecting symlinked repository directories (normalized) before callingos.path.isdir(normalized). This prevents attackers from linking a symlink path that resolves unexpectedly and also makes taint-to-sink flow more explicitly guarded.Change region:
sentinelops-backend/app/services/local_git_service.py_validate_repo_path_for_linkingNo new imports or dependencies are required.
