CVE-2026-2322 is a vulnerability identified in Google Chrome versions prior to 145.0.7632.45 related to an inappropriate implementation of the File input element. The issue allows a remote attacker to craft a malicious HTML page that, when visited by a user who performs certain UI gestures, can lead to UI spoofing. UI spoofing can mislead users by displaying deceptive interface elements, potentially tricking them into performing unintended actions or disclosing sensitive information. The vulnerability is classified under CWE-451 (Incorrect Expression of UI in Web Pages) and has a CVSS v3.1 base score of 5.4, indicating medium severity. The attack vector is network-based (AV:N), requires no privileges (PR:N), but does require user interaction (UI:R). The scope is unchanged (S:U), with no confidentiality impact (C:N), but with low integrity (I:L) and availability (A:L) impacts. Although no exploits are currently known in the wild, the vulnerability poses a risk primarily through social engineering and user deception. The lack of a patch link suggests that users should upgrade to Chrome 145.0.7632.45 or later once available to remediate the issue.

The primary impact of CVE-2026-2322 is on the integrity and availability of the user interface within affected Chrome browsers. UI spoofing can lead to users being deceived into performing harmful actions such as submitting sensitive data to attackers or executing unintended commands. While confidentiality is not directly compromised, the deceptive UI could facilitate phishing or other social engineering attacks, indirectly risking sensitive information. The requirement for user interaction limits automated exploitation but does not eliminate risk, especially in environments where users may be targeted with crafted web content. Organizations relying heavily on Chrome for web access, especially those with users less trained in security awareness, may face increased risk of fraud or operational disruption. The absence of known exploits reduces immediate threat but does not preclude future exploitation attempts.

To mitigate CVE-2026-2322, organizations should prioritize updating Google Chrome to version 145.0.7632.45 or later as soon as the patch is available. Until then, users should be educated about the risks of interacting with untrusted websites and performing unexpected UI gestures. Implementing browser security policies that restrict or monitor the use of file input elements on untrusted sites can reduce exposure. Employing web content filtering and URL reputation services can help block access to malicious pages designed to exploit this vulnerability. Additionally, organizations should consider deploying endpoint protection solutions that detect anomalous browser behavior indicative of UI spoofing attempts. Regular security awareness training emphasizing caution with unfamiliar web content and UI prompts will further reduce the likelihood of successful exploitation.
