Description
## Summary diffs viewer misclassifies proxied remote requests as loopback when `allowRemoteViewer` is disabled ## Current Maintainer Triage - Status: open - Normalized severity: low - Assessment: Shipped v2026.3.28 misclassified proxied diff-viewer requests as local loopback in some cases, a real but low-severity access-control flaw. ## Affected Packages / Versions - Package: `openclaw` (npm) - Latest published npm version: `2026.3.31` - Vulnerable version range: `<=2026.3.28` - Patched versions: `>= 2026.3.31` - First stable tag containing the fix: `v2026.3.31` ## Fix Commit(s) - `30a1690323088fd291abd11643a264a6828a002c` — 2026-03-30T14:17:27-06:00 ## Release Process Note - The fix is already present in released version `2026.3.31`. - This draft looks ready for final maintainer disposition or publication, not additional code-fix work.
