Title

OpenClaw < 2026.3.22 - Unresolved Service Metadata Routing via Bonjour and DNS-SD Discovery

Summary

OpenClaw before 2026.3.22 contains a service discovery vulnerability where TXT metadata from Bonjour and DNS-SD could influence CLI routing even when actual service resolution failed. Attackers can exploit unresolved hints to steer routing decisions to unintended targets by providing malicious discovery metadata.

BREW-OPENCLAW-CLI-CVE-20… (GHSA-RVQR-HRCC-J9VV)

Vulnerability from osv_homebrew – Published: 2026-08-13 17:21 – Updated: 2026-09-20 10:38 – Source website

Summary

OpenClaw: Bonjour/DNS-SD TXT metadata steers CLI routing after failed service resolution

Details

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.

GHSA-RVQR-HRCC-J9VV

Vulnerability from github – Published: 2026-03-26 19:50 – Updated: 2026-04-10 19:38

Summary

OpenClaw: Bonjour/DNS-SD TXT metadata steers CLI routing after failed service resolution

Details

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.
