Technical Analysis
This vulnerability involves missing authorization checks in an actor component of Google Chrome versions before 155.0.8059.39. An attacker who has already compromised the renderer process could exploit this flaw by delivering a specially crafted HTML page, enabling execution of arbitrary code outside the sandbox environment. This elevates the attacker's privileges and could lead to full system compromise. The issue is tracked as CVE-2026-106191 and has been assigned a high severity with a CVSS 3.1 score of 8.3.
Potential Impact
Successful exploitation allows remote code execution outside the sandbox, which can lead to complete compromise of the affected system. The attacker must have already compromised the renderer process to leverage this vulnerability. The impact includes confidentiality, integrity, and availability being fully compromised.
