    ## Summary macOS Wide-Area Discovery Accepts Arbitrary Tailnet Peer as DNS Authority and Exfiltrates Operator Credentials ## Current Maintainer Triage - Status: narrow - Normalized severity: medium - Assessment: Real shipped macOS discovery steering bug, but exploitation needs same-tailnet position, a CA-trusted endpoint, and user selection, so medium not high. ## 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) - `a23c33a681f8c1b22dc793995acc4c5c4b568346` — 2026-03-31T10:04:11+01:00 OpenClaw thanks @nexrin for reporting.
