CVE-2026-2322 is a security vulnerability identified in Google Chrome prior to version 145.0.7632.45. The issue stems from an inappropriate implementation of the File input element within the browser's UI. Specifically, this flaw allows a remote attacker to craft a malicious HTML page that, when visited by a user who performs certain UI gestures, can trigger UI spoofing. UI spoofing involves the attacker presenting fake or misleading interface elements that appear legitimate, potentially tricking the user into performing unintended actions or divulging sensitive information. This vulnerability requires the attacker to convince the user to interact with the crafted page in a specific manner, meaning user interaction is mandatory. There is no indication that authentication is required for exploitation, but the attacker must lure the user to the malicious page. The Chromium security team has assigned a low severity rating to this vulnerability, and as of the publication date, no known exploits have been observed in the wild. The lack of a CVSS score limits precise severity quantification, but the nature of the vulnerability suggests a moderate risk primarily due to social engineering potential rather than direct system compromise. The vulnerability affects all Chrome users running versions before 145.0.7632.45, emphasizing the importance of timely patching.

For European organizations, the primary impact of CVE-2026-2322 lies in the potential for UI spoofing attacks that could facilitate phishing, social engineering, or credential theft. While the vulnerability itself does not directly compromise system integrity or availability, successful exploitation could lead to users being deceived into disclosing sensitive information or performing harmful actions. This is particularly concerning for sectors with high reliance on web applications and sensitive data, such as finance, healthcare, and government services. The requirement for user interaction reduces the likelihood of widespread automated exploitation but does not eliminate risk, especially in environments where users may be targeted via phishing campaigns. The absence of known exploits in the wild currently limits immediate impact, but the vulnerability could be leveraged in targeted attacks. Organizations with large numbers of Chrome users running outdated versions are at higher risk. The impact is thus primarily on confidentiality and user trust rather than direct system compromise.

European organizations should prioritize updating Google Chrome to version 145.0.7632.45 or later to remediate this vulnerability. Beyond patching, user awareness training should emphasize caution when interacting with unexpected or suspicious UI elements, especially on untrusted websites. Implementing browser security policies that restrict or monitor the use of potentially risky web features can reduce exposure. Organizations may also consider deploying browser extensions or security tools that detect or block UI spoofing attempts. Regular audits of browser versions across the enterprise and automated patch management systems will help ensure timely updates. Additionally, employing multi-factor authentication can mitigate the impact of credential theft resulting from UI spoofing. Monitoring for phishing campaigns targeting employees can further reduce risk. Since no known exploits exist yet, proactive defense and user education are key to minimizing potential exploitation.
