In 2025, there were more than 48,000 vulnerabilities published, amounting to over a 20% increase from 2024. More troubling than the sheer volume of vulnerabilities in 2025 is that more than a third of them were given a rating of “high” or “critical” severity. For security teams already stretched too thin, a proactive vulnerability management plan that patches or otherwise remediates all vulnerabilities is too far out of reach.

On January 13, 2025, Fortinet released fixes for a critical-severity FortiSIEM vulnerability (CVE-2025-64155) that stems from improper neutralization of special elements used in OS commands within the phMonitor service (TCP/7900). An unauthenticated, remote threat actor can exploit this vulnerability via crafted TCP requests to execute unauthorized code or commands on affected systems.

In AI-powered security, advantage comes not from automation alone, but from clear insight into how decisions are made. At Arctic Wolf, home to one of the world’s largest commercial security operations centers (SOC), we process over 10 trillion security events weekly. Rather than chasing automation for its own sake, we build AI that scales human expertise – preserving judgment where it matters most. But what is the optimal combination of humans and machines for security operations?

On January 13, 2026, Fortinet released an advisory describing a high-severity remote code execution vulnerability affecting its FortiOS and FortiSwitchManager products. According to Fortinet, the vulnerability stems from a flaw in the CAPWAP Wireless Aggregate Controller Daemon and could allow an unauthenticated, remote threat actor to execute arbitrary code or commands. The vulnerability was discovered internally by Fortinet’s Product Security Team.

On January 7, 2026, Trend Micro released a critical patch for Apex Central on-premises versions below Build 7190, addressing multiple vulnerabilities. The most severe of the vulnerabilities disclosed is CVE-2025-69258, a critical severity vulnerability, which allows unauthenticated threat actors to load malicious DLLs and execute arbitrary code as SYSTEM without user interaction. The advisory also includes two medium-severity denial-of-service vulnerabilities, CVE-2025-69259 and CVE-2025-69260.

On January 7, 2026, fixes were released for a maximum severity vulnerability (CVE-2026-21858) impacting n8n, a workflow automation application primarily used with artificial intelligence. Labeled “Ni8mare” by the researchers who discovered it, the vulnerability allows unauthenticated remote threat actors to take over locally deployed instances via publicly accessible webhook and form endpoints.

Arctic Wolf entered 2025 with momentum and a clear focus: advancing security operations in ways that deliver measurable outcomes for organizations facing an increasingly complex threat environment. As the year comes to a close, we’re building on that momentum — strengthening our platform, expanding globally, and laying the foundation for what comes next in 2026.

On December 19, 2025, MongoDB issued an advisory for CVE-2025-14847, known as “MongoBleed,” a high-severity vulnerability in the server’s zlib-based network compression functionality. This vulnerability affects how the database handles compressed network communications and can cause it to accidentally leak sensitive information from its memory when abused by unauthenticated threat actors. The problem occurs when MongoDB receives a specially crafted message.

On December 17, 2025, Cisco published an advisory detailing a new threat campaign identified on December 10, affecting the Cisco AsyncOS software used on Cisco Secure Email Gateway and Cisco Secure Email and Web Manager. The campaign is exploiting an unpatched zero-day vulnerability, which only affects deployments with the Spam Quarantine feature enabled. It allows threat actors to execute arbitrary commands with root privileges on affected devices. This feature is not enabled by default.

On December 18, 2025, WatchGuard released fixes for CVE-2025-14733, a critical out-of-bounds write vulnerability in the Internet Key Exchange daemon (iked) process used to establish VPN tunnels in Fireware OS, which powers Firebox firewall appliances. Exploitation of this vulnerability allows a remote, unauthenticated threat actor to execute arbitrary code. WatchGuard has confirmed in-the-wild exploitation in their advisory.
