CISA flags four critical security flaws under active exploitation, emphasizing the importance of keeping software up-to-date and taking proactive measures to secure systems against known vulnerabilities. Find out more about these vulnerabilities and how they can be addressed.
CISA has flagged four critical security flaws currently under active exploitation. The vulnerabilities include CVE-2026-2441, a use-after-free vulnerability in Google Chrome; and CVE-2008-0015, a stack-based buffer overflow vulnerability in Microsoft Windows Video ActiveX Control. A report by GreyNoise revealed that about 400 IP addresses were actively exploiting multiple SSRF vulnerabilities, including CVE-2020-7796. Federal Civilian Executive Branch (FCEB) agencies are recommended to apply necessary fixes by March 10, 2026, for optimal protection.
CISA, or the U.S. Cybersecurity and Infrastructure Security Agency, has recently flagged four critical security flaws that are currently under active exploitation. This is based on the latest Known Exploited Vulnerabilities (KEV) update. The list of vulnerabilities includes CVE-2026-2441, a use-after-free vulnerability in Google Chrome; CVE-2024-7694, an arbitrary file upload vulnerability in TeamT5 ThreatSonar Anti-Ransomware versions 3.4.5 and earlier; CVE-2020-7796, a server-side request forgery (SSRF) vulnerability in Synacor Zimbra Collaboration Suite (ZCS); and CVE-2008-0015, a stack-based buffer overflow vulnerability in Microsoft Windows Video ActiveX Control.
The addition of CVE-2026-2441 to the KEV catalog comes days after Google acknowledged that "an exploit for CVE-2026-2441 exists in the wild." However, it is not yet clear how this vulnerability is being weaponized. Typically, such information is withheld until a majority of users are updated with a fix to prevent other threat actors from joining the exploitation bandwagon.
In contrast, a report published by GreyNoise in March 2025 revealed that about 400 IP addresses were actively exploiting multiple SSRF vulnerabilities, including CVE-2020-7796. This cluster of IP addresses targeted susceptible instances in several countries, including the U.S., Germany, Singapore, India, Lithuania, and Japan.
For CVE-2008-0015, a threat encyclopedia by Microsoft notes that when a user visits a web page containing an exploit detected as Exploit:JS/CVE-2008-0015, it may connect to a remote server and download other malware. The worm comes with capabilities such as retrieving and running additional binaries, overwriting certain system files, terminating security-related processes, and even replacing the Windows Hosts file to prevent users from accessing websites associated with security programs.
The TeamT5 ThreatSonar Anti-Ransomware vulnerability is currently being exploited, but it is not clear how. Federal Civilian Executive Branch (FCEB) agencies are recommended to apply necessary fixes by March 10, 2026, for optimal protection.
These four security flaws highlight the importance of keeping software up-to-date and taking proactive measures to secure systems against known vulnerabilities. As organizations continue to navigate the ever-evolving threat landscape, it is crucial that they prioritize cybersecurity awareness and invest in robust security protocols to prevent exploitation.
In this context, cybersecurity professionals, IT teams, and individual users are urged to monitor their systems for any signs of these vulnerabilities and apply necessary patches as soon as possible. The recent KEV update serves as a stark reminder of the ongoing threat landscape and the need for continuous vigilance.
Furthermore, it is essential to note that the use of patched software does not guarantee complete security against all threats. However, taking proactive steps to address known vulnerabilities can significantly reduce the risk of exploitation.
In conclusion, the recent KEV update by CISA underscores the critical importance of staying informed about emerging security flaws and taking swift action to protect systems from known vulnerabilities. As we continue to navigate the complex threat landscape, it is crucial that organizations prioritize cybersecurity awareness and invest in robust security protocols to prevent exploitation.
