CVE-2025-11212 is a vulnerability identified in the Media component of Google Chrome on Windows platforms prior to version 141.0.7390.54. The flaw arises from an inappropriate implementation that allows a remote attacker to perform domain spoofing attacks. Specifically, the attacker crafts a malicious HTML page that, when visited, can exploit certain UI gesture interactions by the user to manipulate the browser's display of the domain. This manipulation can deceive users into believing they are interacting with a legitimate domain when they are not, facilitating phishing or other social engineering attacks. The attack requires the victim to engage in specific UI gestures, indicating that user interaction is necessary for exploitation. The vulnerability impacts the integrity and confidentiality of user sessions by undermining trust in the browser's address bar and domain indicators. There are no known exploits in the wild at the time of publication, and no CVSS score has been assigned. The vulnerability was publicly disclosed on November 6, 2025, with the patch released in Chrome version 141.0.7390.54. The absence of a CVSS score necessitates an independent severity assessment based on the attack vector, impact, and exploitation complexity.

For European organizations, this vulnerability poses a significant risk primarily through phishing and social engineering attacks that exploit domain spoofing. By misleading users about the legitimacy of websites, attackers can steal credentials, deploy malware, or conduct fraudulent transactions. Organizations in sectors such as finance, government, healthcare, and critical infrastructure are particularly vulnerable due to the high value of their data and services. The requirement for user interaction reduces the likelihood of automated widespread exploitation but does not eliminate targeted attacks against high-value individuals or employees. The confidentiality and integrity of sensitive information are at risk, potentially leading to data breaches, financial loss, and reputational damage. Additionally, the widespread use of Google Chrome in Europe amplifies the potential impact, especially in environments where patch management is delayed or user awareness is low.

1. Immediate update of all affected Google Chrome installations on Windows to version 141.0.7390.54 or later to apply the official patch. 2. Implement enterprise-wide browser update policies to ensure timely deployment of security patches. 3. Conduct user awareness training focusing on recognizing suspicious UI behaviors and the risks of interacting with untrusted web content. 4. Employ browser security extensions or enterprise security solutions that can detect or block domain spoofing attempts. 5. Monitor network traffic and browser logs for unusual activities indicative of phishing or spoofing attempts. 6. Encourage the use of multi-factor authentication (MFA) to reduce the impact of credential theft resulting from successful spoofing. 7. For high-risk environments, consider restricting browser usage to managed and monitored devices with hardened configurations. 8. Collaborate with cybersecurity teams to conduct phishing simulations that incorporate domain spoofing scenarios to improve user resilience.
