CVE-2025-14372 is a use-after-free vulnerability identified in the Password Manager component of Google Chrome prior to version 143.0.7499.110. Use-after-free vulnerabilities occur when a program continues to use memory after it has been freed, leading to undefined behavior that attackers can exploit to execute arbitrary code or escalate privileges. In this case, the flaw allows a remote attacker to craft a malicious HTML page that triggers the vulnerability, potentially enabling sandbox escape. Sandbox escape is critical because it breaks the isolation that browsers enforce to protect the underlying operating system and user data from malicious web content. The vulnerability does not require authentication but likely requires the victim to visit a malicious webpage, making it a remote code execution vector with user interaction. Although no public exploits are currently known, the medium severity rating by Chromium indicates a significant risk that could be leveraged in targeted attacks. The vulnerability affects a widely used browser component, increasing the potential attack surface. The lack of a CVSS score means severity must be inferred from the nature of the vulnerability, its exploitability, and potential impact. The vulnerability was publicly disclosed on December 12, 2025, with a patch available in Chrome 143.0.7499.110, emphasizing the need for timely updates.

For European organizations, the impact of CVE-2025-14372 could be substantial due to the widespread use of Google Chrome in enterprise and public sectors. Successful exploitation could allow attackers to escape the browser sandbox, leading to unauthorized access to the host system, data theft, or further lateral movement within corporate networks. This could compromise sensitive information, including credentials managed by the browser's Password Manager, potentially leading to broader breaches. The vulnerability's remote exploitation capability increases the risk of drive-by attacks through malicious websites or phishing campaigns. Organizations in sectors with high regulatory requirements for data protection, such as finance, healthcare, and government, could face compliance violations and reputational damage if exploited. The absence of known exploits currently provides a window for proactive defense, but the potential for rapid weaponization necessitates urgent patching and monitoring. The impact on availability is limited, but confidentiality and integrity could be severely affected.

1. Immediately update all Google Chrome installations to version 143.0.7499.110 or later to apply the official patch addressing this vulnerability. 2. Implement strict Content Security Policies (CSP) to restrict the execution of untrusted scripts and reduce the risk of malicious HTML content triggering the vulnerability. 3. Employ browser isolation technologies or sandboxing at the enterprise level to contain potential exploitation attempts. 4. Educate users about the risks of visiting untrusted websites and phishing attacks that could deliver malicious payloads exploiting this vulnerability. 5. Monitor network traffic and endpoint logs for unusual activity indicative of sandbox escape attempts or exploitation. 6. Disable or restrict the use of the Password Manager feature in Chrome where feasible, especially in high-risk environments, until patches are fully deployed. 7. Coordinate with IT asset management to ensure all devices, including remote and mobile endpoints, receive timely updates. 8. Stay informed through official Google security advisories and threat intelligence feeds for any emerging exploit reports or additional mitigations.
