CISA Tags Recently Patched Chrome Bug as Actively Exploited, Urging Immediate Action for Federal Agencies and Network Defenders Alike
In a recent development that has sent shockwaves through the cybersecurity community, the Cybersecurity and Infrastructure Security Agency (CISA) has identified a high-severity vulnerability in Google Chrome that has been exploited by malicious actors in the wild. The identified bug, CVE-2025-4664, was previously discovered by Solidlab security researcher Vsevolod Kokorin on May 5th and shared technical details online.
According to CISA, the vulnerability is due to insufficient policy enforcement in Google Chrome's Loader component. This flaw allows remote attackers to leak cross-origin data via maliciously crafted HTML pages. The severity of this vulnerability has been deemed high by CISA, which warns that successful exploitation can lead to significant risks for federal agencies and other organizations.
Google released security updates to patch the vulnerability on Wednesday, May 7th. However, it is imperative that all users and organizations take immediate action to secure their systems against ongoing attacks exploiting this zero-day flaw.
The identified vulnerability has been labeled as actively exploited by CISA, with evidence suggesting that malicious actors have already utilized CVE-2025-4664 in recent attacks. This designation underscores the critical nature of the bug and emphasizes the need for swift remediation.
CISA's warning is part of a larger trend in which the agency continues to track and address emerging threats in the cybersecurity landscape. By identifying and addressing high-severity vulnerabilities like CVE-2025-4664, CISA plays a crucial role in protecting federal agencies and other organizations from potential breaches.
In addition to its warning about the Chrome zero-day vulnerability, CISA also highlighted the importance of patching this bug within three weeks of the advisory being issued. This deadline applies specifically to U.S. Federal Civilian Executive Branch (FCEB) agencies but is also advisable for all network defenders who prioritize their organization's security.
As part of its efforts to combat cyber threats, CISA has emphasized that federal civilian executive branch agencies must patch this vulnerability by May 7th to secure their systems against potential breaches. This directive underscores the critical nature of zero-day vulnerabilities and serves as a reminder of the importance of staying vigilant in the ever-evolving cybersecurity landscape.
While the severity of CVE-2025-4664 has been deemed high, it is essential for organizations to prioritize patching this vulnerability alongside other security measures. By doing so, network defenders can minimize the risk of successful exploitation and protect their organization's systems from potential breaches.
In summary, the identified Chrome zero-day vulnerability, CVE-2025-4664, has been labeled as actively exploited by CISA due to its high severity. Urged to take immediate action to patch this bug within three weeks, all network defenders are advised to prioritize securing their systems against ongoing attacks exploiting this zero-day flaw.
