Technical Analysis
CVE-2026-106409 is an incorrect reference resolution vulnerability in the WebAppInstalls feature of Google Chrome on Mac platforms before version 155.0.8059.39. An attacker with control over the renderer process can exploit this flaw by sending specially crafted network traffic, enabling arbitrary code execution outside the browser sandbox. This breaks the isolation normally enforced by the sandbox, increasing the risk of system compromise.
Potential Impact
Successful exploitation allows arbitrary code execution outside the sandbox by an attacker who already has compromised the renderer process. This elevates the attacker's privileges and can lead to further system compromise beyond the browser sandbox. The severity is rated medium by Chromium security.
Mitigation Recommendations
Google has released an official fix in Chrome version 155.0.8059.39. Users should update to this version or later to remediate the vulnerability. No additional mitigation steps are indicated by the vendor advisory.
