CVE-2026-2316 is a vulnerability identified in Google Chrome versions prior to 145.0.7632.45, stemming from insufficient policy enforcement related to Frames. Frames are HTML elements used to embed content within a webpage, and improper enforcement of security policies in these frames can allow attackers to manipulate the user interface. Specifically, this vulnerability enables remote attackers to craft malicious HTML pages that perform UI spoofing, misleading users by displaying fake or deceptive interface components that appear legitimate. This can trick users into performing unintended actions, such as clicking on malicious links or entering sensitive information into fraudulent forms. The vulnerability is classified under CWE-451, indicating a failure to enforce security policies adequately. The CVSS 3.1 base score is 6.5, with vector AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:H/A:N, meaning the attack can be launched remotely over the network with low attack complexity, requires no privileges, but does require user interaction. The impact is primarily on integrity, as the attacker can manipulate the UI to deceive users, but there is no direct impact on confidentiality or availability. No known exploits are currently active in the wild, and no official patches or mitigation links are provided in the data, though updating to version 145.0.7632.45 or later is implied. This vulnerability poses a risk to any organization or individual using affected Chrome versions, especially in environments where users might be targeted by phishing or social engineering attacks leveraging UI spoofing.

The primary impact of CVE-2026-2316 is on the integrity of user interactions within Google Chrome. By enabling UI spoofing, attackers can deceive users into performing actions they did not intend, such as submitting credentials, authorizing transactions, or clicking malicious links. This can lead to downstream consequences including credential theft, unauthorized access, or malware installation. Since the vulnerability requires user interaction, the risk is elevated in environments where users are less security-aware or where phishing attacks are common. There is no direct impact on confidentiality or availability, but the indirect effects of successful UI spoofing can be significant. Organizations worldwide that rely on Chrome for web access, especially those with high-value targets or sensitive data, face increased risk of social engineering attacks exploiting this vulnerability. The absence of known exploits in the wild reduces immediate risk, but the medium severity and ease of exploitation warrant prompt attention to prevent future attacks.

To mitigate CVE-2026-2316, organizations should prioritize updating Google Chrome to version 145.0.7632.45 or later, where the vulnerability is addressed. Since no official patch links are provided, users should monitor official Google Chrome security advisories for updates. Additionally, organizations should implement user training focused on recognizing phishing and UI spoofing attempts, emphasizing caution when interacting with unfamiliar or suspicious web content. Deploying browser security extensions that detect or block malicious scripts and frames can add a layer of defense. Network-level protections such as web filtering and intrusion prevention systems should be configured to block known malicious URLs and content. For high-risk environments, consider restricting the use of frames or sandboxing browser sessions to limit potential attack surfaces. Continuous monitoring for suspicious user activity and incident response readiness are also recommended to quickly address any exploitation attempts.
