CVE-2025-11216 is a vulnerability identified in Google Chrome's Storage implementation on Mac platforms prior to version 141.0.7390.54. The flaw allows a remote attacker to craft a specially designed video file that can trigger domain spoofing within the browser. Domain spoofing here means that the attacker can manipulate the browser's UI or storage-related mechanisms to make a malicious domain appear as a legitimate one, potentially deceiving users into trusting fraudulent websites or content. The vulnerability is classified with a CVSS score of 6.3 (medium severity), reflecting its moderate impact on confidentiality, integrity, and availability. The attack vector is network-based (AV:N), requires no privileges (PR:N), but does require user interaction (UI:R), such as opening or playing the crafted video file. The scope is unchanged (S:U), meaning the impact is limited to the vulnerable component without affecting other system components. Although no known exploits are currently reported in the wild, the vulnerability poses a risk for phishing and social engineering attacks that leverage domain spoofing to trick users into divulging sensitive information or executing malicious actions. The vulnerability is specific to Mac versions of Chrome, highlighting a platform-specific implementation issue in the Storage subsystem. The lack of patch links suggests that the fix is included in Chrome version 141.0.7390.54 or later, and users should upgrade promptly to mitigate the risk.

For European organizations, this vulnerability could facilitate targeted phishing campaigns or social engineering attacks that exploit domain spoofing to deceive users. Confidentiality could be compromised if users are tricked into submitting credentials or sensitive data to spoofed domains. Integrity and availability impacts are limited but possible if attackers manipulate stored data or cause browser instability through crafted media. Organizations with a significant Mac user base running outdated Chrome versions are at higher risk. Sectors such as finance, government, and critical infrastructure could be targeted due to the potential for credential theft or unauthorized access. The requirement for user interaction limits automated exploitation but does not eliminate risk, especially in environments where users frequently handle multimedia content. The absence of known exploits in the wild reduces immediate threat but does not preclude future exploitation once the vulnerability becomes publicly known.

European organizations should prioritize updating all Mac-based Chrome browsers to version 141.0.7390.54 or later to remediate the vulnerability. Implement strict update policies and automated patch management to ensure timely deployment. Educate users about the risks of opening unsolicited or unexpected video files, especially from untrusted sources. Employ email and web filtering solutions to detect and block malicious multimedia content. Consider deploying endpoint security solutions capable of analyzing and sandboxing media files before execution. Monitor network traffic and browser logs for unusual domain resolution or spoofing indicators. Additionally, enforce multi-factor authentication (MFA) to reduce the impact of credential theft resulting from phishing attacks leveraging this vulnerability. Regularly review and update incident response plans to include scenarios involving domain spoofing and social engineering attacks.
