GHSA-2mc2-g238-722j · OpenClaw affected by iMessage remote attachment SCP hardening (strict host-key checks and remoteHost validation)

This page contains facts from public vulnerability sources. Check the original advisory before updating.

## Summary Remote iMessage attachment fetches used SCP with trust-on-first-use host-key behavior and accepted unvalidated remote host tokens. Before the fix: - SCP used `StrictHostKeyChecking=accept-new` in the remote attachment path. - `channels.imessage.remoteHost` was not validated as a strict SSH host token. ## Impact In remote iMessage deployments that use SCP attachment fetching, a first-connection MITM/DNS-poisoning scenario could cause the wrong host key to be trusted. Unsafe remote host token values could also alter SCP argument semantics. ## Affected Packages / Versions - Package: `openclaw` (npm) - Latest published npm version currently affected: `2026.2.17` - Vulnerable range (structured field): `<= 2026.2.17` - Patched version (pre-set for next release): `>= 2026.2.19` ## Fix The fix hardens remote attachment SSH/SCP handling by: - requiring `StrictHostKeyChecking=yes` for SCP and SSH tunnel paths, - adding strict `remoteHost` normalization/validation, - adding `--` argument barrier for SCP remote source parsing, - validating `channels.imessage.remoteHost` in config schema, - rejecting unsafe auto-detected host tokens at runtime. ## Fix Commit(s) - Pushed to `main`: 49d0def6d1e88f002026b1d2a35aa615d48a751a OpenClaw thanks @allsmog for reporting.
