Anthropic OSS Scanner Uncovers 29,439 Vulnerability Candidates in Open Source Projects, Delivering 6,157 Reports and 516 Fixes

Anthropic has published detailed metrics from its six-month coordinated vulnerability disclosure program that preceded the launch of its automated OSS Scanner service. The company’s models identified 29,439 potential vulnerabilities, of which external firms verified 6,123 candidates and confirmed 5,674 as genuine issues. From the 6,157 reports sent to maintainers across 591 projects, only 516 fixes have been merged so far, representing an 8.4 percent remediation rate among delivered reports. Anthropic emphasizes that 78 percent of reports were sent without independent human triage, and the new OSS Scanner now delivers fully model-generated findings directly to approved projects. Maintainers from PostgreSQL, curl, OpenSSL, wolfSSL and HotCRP have praised the quality of recent reports while noting that earlier AI-generated submissions were largely noise. The dashboard snapshot dated 2 October 2026 shows that 584 identifiers (219 CVE and 365 GHSA) have been issued, yet many confirmed issues remain in the triage queue due to limited human resources.
