Overview

CVE-2026-100532 is a high-severity vulnerability. It was published on September 26, 2026 and has a CVSS 3.1 base score of 8.1 (HIGH).

This vulnerability has a CVSS 3.1 base score of 8.1, rated HIGH. It can be exploited remotely over the network. Some level of privileges is required for exploitation.

Technical description

@openclaw/whatsapp (npm) before 2026.8.1 exposes the WhatsApp login tool through the generic channel-tool path without preserving the originating sender's owner status, so the owner-only tool boundary is not enforced. An admitted non-owner sender able to steer the tool can request a forced login and receive a new QR code for a configured account, disconnecting the Gateway's WhatsApp account and causing loss of availability; full account relinking additionally requires the attacker to scan the returned QR code with another phone. The issue affects the owner-only tool boundary rather than WhatsApp transport authentication. Fixed in 2026.8.1.

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
