GHSA-2MC2-G238-722J
Vulnerability from github – Published: 2026-03-03 21:35 – Updated: 2026-03-03 21:35Summary
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.

Mitigation
Certificates should be carefully managed and checked to assure that data are encrypted with the intended owner's public key.
Mitigation
If certificate pinning is being used, ensure that all relevant properties of the certificate are fully validated before the certificate is pinned, including the hostname.
CAPEC-459: Creating a Rogue Certification Authority Certificate
An adversary exploits a weakness resulting from using a hashing algorithm with weak collision resistance to generate certificate signing requests (CSR) that contain collision blocks in their "to be signed" parts. The adversary submits one CSR to be signed by a trusted certificate authority then uses the signed blob to make a second certificate appear signed by said certificate authority. Due to the hash collision, both certificates, though different, hash to the same value and so the signed blob works just as well in the second certificate. The net effect is that the adversary's second X.509 certificate, which the Certification Authority has never seen, is now signed and validated by that Certification Authority.
CAPEC-475: Signature Spoofing by Improper Validation
An adversary exploits a cryptographic weakness in the signature verification algorithm implementation to generate a valid signature without knowing the key.
