MITRE and CISA Release 2025 Top 25 Most Dangerous Software Weaknesses
MITRE, in collaboration with the Cybersecurity and Infrastructure Security Agency (CISA) and the Homeland Security Systems Engineering and Development Institute (HSSEDI), has published the 2025 list of the Top 25 Most Dangerous Software Weaknesses. This annual ranking is based on the analysis of over 39,000 CVE records from June 2024 to June 2025, scoring each weakness by severity and frequency. The list highlights critical software flaws such as Cross-Site Scripting (CWE-79), SQL Injection (CWE-89), and Cross-Site Request Forgery (CWE-352), with notable changes in rankings and several new entries including various buffer overflows and improper access control issues.
CISA emphasizes the importance of this list for organizations aiming to reduce vulnerabilities, improve cost efficiency by addressing weaknesses early in the software lifecycle, and strengthen trust through Secure by Design principles. The Top 25 serves as a guide for developers, product teams, and consumers to prioritize mitigation efforts, make informed purchasing decisions, and adopt secure engineering practices to protect against the most commonly exploited software weaknesses.
