# NousResearch/hermes-agent · RPC socket file permissions security hardening

## Open now

- Nothing open on GitHub.

A reported bug and multiple fix attempts address RPC sockets being created with world-accessible permissions, proposing restriction to owner-only access to prevent local privilege escalation.

## TL;DR

- 5 member(s): 0 open issue(s), 1 closed issue(s), 0 open PR(s), 1 merged PR(s), 3 PR(s) closed without merging.
- A fix was merged to main in PR #14217. Verify it addresses your case.
- **Recommended:** read PR #14217 (and any competing PRs below) before filing. Confirm the merged change covers your symptom.

## Maintainer resolution verdict

- Internal-tracker verdict over this cluster's issue members: `unresolved`. This is distinct from the fix status above. Weigh it yourself.

## How this cluster was grouped

- Link evidence (`STRUCTURAL_SPANNING`): every member is connected by structural evidence: shared changed files, or a closing/superseded reference.
- Pairwise link density `0.40`: the share of member pairs that carry a link, counting a structural link in full and a relevance-only link at 0.36. `1.00` means every pair is linked.
