Inappropriate implementation in Downloads in Google Chrome prior to 145.0.7632.45 allowed a remote attacker to perform UI spoofing via a crafted HTML page. This vulnerability is classified as a medium severity issue with a CVSS score of 4.3. The risk to organizations includes potential deception of users who may be misled by manipulated interface elements, which can lead to unauthorized actions or data leakage.
Given that this vulnerability affects a widely used web browser, organizations should prioritize patching immediately. The exploitation potential is moderate, and while there is currently no known exploit or public proof of concept, this does not diminish the importance of addressing the vulnerability promptly.
This vulnerability presents a risk that could be leveraged by attackers aiming to perform phishing attacks or other malicious activities. As such, ensuring that users are using the latest version of Google Chrome is crucial to maintaining security against such threats.
Organizations should not only patch their systems but also conduct a review of their user training programs to ensure that employees are aware of such risks and how to recognize potential spoofing attempts.
Vulnerability Details
The vulnerability CVE-2026-2323 stems from an inappropriate implementation in the Downloads feature of Google Chrome. The specific issue allows remote attackers to perform UI spoofing via a crafted HTML page. The CVSS score assigned to this vulnerability is 4.3, indicating a medium severity level.
The affected product is Google Chrome, specifically any version prior to 145.0.7632.45. The vulnerability was published on February 11, 2026, and is classified under CWE-451.
Technical Analysis
The root cause of CVE-2026-2323 is linked to a flaw in the implementation of the Downloads feature that does not properly validate the user interface elements displayed to the user. This creates a potential attack vector where an attacker can craft a malicious HTML page that tricks users into believing they are interacting with legitimate elements of the browser.
The attack vector for this vulnerability is network-based, requiring low attack complexity. No privileges are required for exploitation, but user interaction is necessary as the user must visit the crafted HTML page.
The impact on confidentiality is none, while the integrity impact is low. There is no availability impact associated with this vulnerability.
Risk & Impact Analysis
Organizations deploying Google Chrome with versions below 145.0.7632.45 face risks related to UI spoofing, which could mislead users and facilitate phishing attacks. The potential blast radius is significant due to the widespread use of the Chrome browser, increasing the urgency for organizations to address this vulnerability in their patch cycle.
Given the CVSS score of 4.3, organizations should treat this vulnerability with moderate urgency. Regular updates and user training are essential components in mitigating the risks associated with such vulnerabilities.
