# NousResearch/hermes-agent · Multiplex profile .env leaking into shared process env

## Open now

- Nothing open on GitHub.

These items concern a bug where loading a profile-scoped .env file with override=True writes that profile's variables into the shared process environment, potentially exposing credentials across profiles in multiplex mode. The group includes a bug report and two proposed fixes targeting the same issue.

## TL;DR

- 4 member(s): 0 open issue(s), 1 closed issue(s), 0 open PR(s), 1 merged PR(s), 2 PR(s) closed without merging.

## Maintainer resolution verdict

- Internal-tracker verdict over this cluster's issue members: `resolved` · deciding PR(s): `pr-101244`. 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evidence (`STRUCTURAL_SPANNING`): every member is connected by structural evidence: shared changed files, or a closing/superseded reference.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 `0.50`: 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.

## Closed / duplicate issues

- #77562: \[Bug\]: multiplex — a turn-scoped load_hermes_dotenv() writes the active profile's entire .env into the shared process os.environ (override=True), cross-contaminating every other profile
