Inappropriate implementation in DevTools in Google Chrome prior to 136.0.7103.59 allowed a remote attacker who convinced a user to engage in specific UI gestures to bypass discretionary access control via a crafted HTML page. This vulnerability is classified as critical due to its high CVSS score of 9.8, indicating severe potential impacts on confidentiality, integrity, and availability.
Risk to organizations includes unauthorized access and manipulation of sensitive data, making it imperative for security teams to act swiftly. Although the vulnerability does not have known exploits at this time, the potential for remote exploitation underscores the urgency for immediate remediation.
Organizations should prioritize patching immediately to mitigate the risks associated with this vulnerability. Staying updated with the latest security patches is crucial in defending against potential attacks leveraging this flaw.
The vulnerability has been analyzed and classified under CWE-838, which indicates a failure to enforce access controls. This highlights the necessity for developers to implement more robust security measures within applications.
Vulnerability Details
The vulnerability exists due to inappropriate implementation in the DevTools of Google Chrome. Specifically, it allows attackers to exploit UI gestures to bypass access controls. The CVSS score of 9.8 underscores its critical nature, with high impacts on confidentiality, integrity, and availability.
Affected products include Google Chrome versions prior to 136.0.7103.59, with the vulnerability being publicly disclosed on May 5, 2025.
Technical Analysis
The root cause of this vulnerability stems from the improper handling of UI gestures within the DevTools, leading to an oversight in access control enforcement. The attack vector is network-based, requiring no privileges or user interaction, which increases its exploitability.
The attack complexity is low, and the potential impacts include significant confidentiality, integrity, and availability issues, making this a high-priority concern for organizations relying on Chrome for secure operations.
Risk & Impact Analysis
Organizations relying on Google Chrome for daily operations face tangible risks due to this vulnerability. The ability for attackers to bypass access controls can lead to unauthorized data access and manipulation, posing significant threats to sensitive information.
Given the critical severity rating, organizations should assess their deployment of Chrome and prioritize the necessary updates. The implications of an attack leveraging this vulnerability could result in a large blast radius, affecting not only individual users but potentially impacting broader organizational security.
