# NousResearch/hermes-agent · env parser splitting secrets on embedded KEY= substrings

## Open now

- Nothing open on GitHub.

These items concern a vulnerability and related fixes in the .env sanitizer where values containing a KEY= substring could be incorrectly split, corrupting or leaking secret values. The work addresses parsing logic to preserve opaque env values.

## 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.

- **Recommended:** read PR #71005 (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evidence (`STRUCTURAL_SPANNING`): every member is connected by structural evidence: shared changed files, or a closing/superseded reference.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 `0.50`: 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.
