CVE-2026-2320 is a vulnerability identified in Google Chrome prior to version 145.0.7632.45, stemming from an inappropriate implementation of the File input element. The flaw enables a remote attacker to craft malicious HTML pages that exploit specific user interface (UI) gestures performed by the user to execute UI spoofing attacks. UI spoofing involves deceiving users by displaying fake or misleading UI elements, potentially causing users to disclose sensitive information or perform unintended actions. This vulnerability requires the attacker to convince the user to interact with the crafted page in a particular way, making social engineering a key component of exploitation. Although no known exploits have been reported in the wild, the vulnerability poses a risk to the confidentiality and integrity of user interactions within the browser. The absence of a CVSS score suggests the need for a severity assessment based on impact and exploitability factors. The vulnerability does not require authentication but depends on user interaction, limiting the attack scope to users who visit malicious or compromised websites. The flaw affects a widely used browser, increasing the potential attack surface globally. The issue was publicly disclosed on February 11, 2026, and patched in Chrome version 145.0.7632.45. Organizations relying heavily on Chrome for web access should prioritize patching to mitigate risks associated with UI spoofing, which can lead to phishing, credential theft, or unauthorized actions.

For European organizations, the impact of CVE-2026-2320 centers on the potential for UI spoofing attacks that can undermine user trust and lead to credential theft, phishing, or unauthorized transactions. Since Chrome is a dominant browser in Europe, many organizations' employees and customers may be exposed if they use vulnerable versions. The vulnerability could facilitate targeted social engineering campaigns, especially against sectors with high-value data such as finance, healthcare, and government. UI spoofing can compromise the integrity of user interactions, potentially leading to data leakage or fraudulent activities. Although the vulnerability does not directly compromise system availability, the indirect effects of successful attacks could disrupt business operations and damage reputations. The lack of known exploits reduces immediate risk, but the medium severity indicates a need for proactive mitigation. Organizations with remote or hybrid workforces relying on Chrome for accessing corporate resources are particularly at risk. Failure to patch could also expose organizations to regulatory scrutiny under GDPR if user data is compromised through phishing or spoofing attacks.

The primary mitigation is to update Google Chrome to version 145.0.7632.45 or later, which contains the fix for this vulnerability. Organizations should enforce automated browser updates or centrally manage Chrome deployments to ensure timely patching. User education is critical: train users to recognize suspicious UI behaviors and avoid interacting with untrusted or unexpected file input prompts. Implement browser security policies that restrict or monitor file input usage on untrusted sites. Employ web filtering solutions to block access to known malicious or suspicious websites that could host crafted HTML pages exploiting this vulnerability. Consider deploying endpoint protection tools capable of detecting and blocking phishing or UI spoofing attempts. Regularly audit browser extensions and plugins to prevent additional attack vectors. For high-risk sectors, consider multi-factor authentication to reduce the impact of credential theft resulting from UI spoofing. Finally, monitor security advisories from Google and update incident response plans to include scenarios involving UI spoofing attacks.
