MITRE has released its 2025 Top 25 Most Dangerous Software Weaknesses list, identifying root causes of 39,080 Common Vulnerability and Exposure (CVE™) records this year. Common vulnerabilities are easy to spot and exploit, allowing attackers to take control of systems, steal sensitive information, or disrupt applications.

Developers, security teams, and executives now have a plan to prioritize fixes and improve software development lifecycles (SDLC). The annual ranking using real CVE data is now more important due to rising cyber threats.
