CVE-2026-35659
OpenClaw: Bonjour/DNS-SD TXT metadata steers CLI routing after failed service resolution
Description
## Summary Bonjour and DNS-SD TXT metadata could still steer CLI routing even when actual service resolution failed, allowing unresolved hints to influence the chosen target. ## Affected Packages / Versions - Package: `openclaw` (npm) - Affected: < 2026.3.22 - Fixed: >= 2026.3.22 - Latest released tag checked: `v2026.3.23-2` (`630f1479c44f78484dfa21bb407cbe6f171dac87`) - Latest published npm version checked: `2026.3.23-2` ## Fix Commit(s) - `deecf68b59a9b7eea978e40fd3c2fe543087b569` ## Release Status The fix shipped in `v2026.3.22` and remains present in `v2026.3.23` and `v2026.3.23-2`. ## Code-Level Confirmation - src/infra/bonjour-discovery.ts now resolves and returns only concrete endpoints instead of falling back to unresolved TXT host and port hints. - src/cli/gateway-cli/discover.ts consumes only the fail-closed resolved endpoint path. OpenClaw thanks @nexrin for reporting.
