Which Code Vulnerabilities Actually Get Fixed? New Code Security Data from 50,000+ Repos
Mar 30, 2026
Most application security (AppSec) teams know their OWASP Top 10, the industry-standard list of the most critical software security risks. Fewer know which of those categories their organization actually fixes. In conversations with security teams, I hear the same story: "We prioritize criticals, so the important stuff gets handled." The data tells a different story. Fix rates vary dramatically by OWASP vulnerability class, and not in the ways most teams expect. The data comes from Semgrep's Remediation at Scale report , which analyzed anonymized remediation patterns across 50,000+ repositories and hundreds of organizations during 2025. The methodology is straightforward: group organizations into two cohorts by fix rate (top 15% as "leaders," remaining 85% as "field"), then compare what each group actually does differently. The gap between leaders and the field isn't about detection quality or prioritization frameworks. Both cohorts apply the s...
