CVE-2026-100532: Missing Authorization in openclaw whatsapp
CVE-2026-100532 is a missing authorization vulnerability in the @openclaw/whatsapp npm package before version 2026.8.1. It allows non-owner users to access an owner-only WhatsApp login tool via a generic channel-tool path, bypassing the intended owner-only restrictions. This can lead to forced login requests that disconnect the Gateway's WhatsApp account, causing availability loss. Exploitation requires the attacker to scan a returned QR code with another phone to fully relink the account. The issue is fixed in version 2026.8.1.
AI Analysis
Technical Summary
@openclaw/whatsapp versions prior to 2026.8.1 expose a WhatsApp login tool through a generic channel-tool path without enforcing the owner-only boundary. This missing authorization allows a non-owner sender with limited privileges to request a forced login and obtain a new QR code for a configured WhatsApp account. The forced login disconnects the Gateway's WhatsApp account, resulting in loss of availability. Full account relinking requires the attacker to scan the QR code with a separate device. The vulnerability affects the owner-only tool boundary rather than WhatsApp transport authentication. The issue is resolved in version 2026.8.1.
Potential Impact
An attacker with non-owner sender privileges can force a login on the Gateway's WhatsApp account, causing disconnection and loss of availability. Full account takeover requires scanning the QR code with another phone, so the impact is primarily denial of service unless the attacker can physically scan the QR code. This vulnerability compromises the owner-only access control for the login tool but does not bypass WhatsApp's own authentication mechanisms.
Mitigation Recommendations
Upgrade to @openclaw/whatsapp version 2026.8.1 or later, where this missing authorization issue is fixed. No other mitigation is required as the vulnerability is resolved by the official patch.
