CVE-2025-11216 is a security vulnerability identified in Google Chrome's Storage implementation on Mac platforms prior to version 141.0.7390.54. The flaw arises from an inappropriate handling of storage mechanisms related to video files, which enables a remote attacker to craft a malicious video file that can spoof domain information. Domain spoofing in this context means that an attacker can make a malicious site or content appear as if it originates from a legitimate domain, potentially deceiving users and bypassing security controls that rely on domain validation. The vulnerability does not require prior authentication but likely requires the victim to interact with the crafted video file, such as opening or playing it within Chrome. Although the Chromium security team has classified this issue as low severity, the lack of a CVSS score necessitates an independent evaluation. There are no known exploits in the wild, indicating that active exploitation is not currently observed. The vulnerability affects only Mac versions of Chrome before 141.0.7390.54, limiting the scope to users on that platform and version. The technical root cause is an inappropriate implementation in the Storage component, which may involve incorrect validation or handling of metadata or domain-related information embedded in video files. This flaw could be leveraged in phishing or social engineering attacks to increase their success by making malicious content appear trustworthy. The vulnerability was published on November 6, 2025, with the reservation date on September 30, 2025. No patches or exploit code links were provided in the source information, but updating to the fixed version is the primary remediation.

For European organizations, the primary impact of CVE-2025-11216 lies in the potential for domain spoofing attacks that can facilitate phishing, social engineering, or other deception-based intrusions. This could lead to unauthorized disclosure of sensitive information if users are tricked into submitting credentials or confidential data to spoofed domains. The integrity of communications and trust in web-based services could be undermined, especially in sectors relying heavily on Chrome on Mac devices, such as finance, legal, and technology firms. Availability impact is minimal as the vulnerability does not enable denial-of-service conditions. Since exploitation requires crafted video files and user interaction, the attack vector is somewhat limited but still significant in environments where users frequently handle multimedia content. The lack of known exploits reduces immediate risk but does not eliminate the threat, especially as attackers may develop exploits in the future. Organizations with remote or hybrid workforces using Mac devices are particularly at risk if update policies are lax. Overall, the impact is moderate but warrants timely remediation to prevent potential escalation or combined attacks.

1. Immediately update all Google Chrome installations on Mac devices to version 141.0.7390.54 or later to apply the fix for CVE-2025-11216. 2. Implement strict policies for handling and opening video files, especially those received from untrusted or external sources, including email attachments and downloads. 3. Employ endpoint security solutions capable of scanning and blocking malicious multimedia files before they reach users. 4. Educate users about the risks of interacting with unsolicited or suspicious video content and the importance of verifying domain authenticity even when content appears legitimate. 5. Monitor network traffic and logs for unusual domain resolution or spoofing attempts that could indicate exploitation attempts. 6. Consider deploying browser security extensions or configurations that enhance domain validation and reduce the risk of spoofing. 7. Coordinate with IT asset management to identify all Mac devices running vulnerable Chrome versions and prioritize patching. 8. For high-security environments, restrict the use of Chrome on Mac or enforce additional sandboxing and isolation measures for multimedia processing. 9. Stay informed on updates from Google and Chromium security advisories for any new patches or exploit disclosures related to this vulnerability.
