Summary
Anthropic has launched a public coordinated vulnerability disclosure dashboard tracking security issues discovered using Claude Mythos Preview, its advanced vulnerability-finding AI model. Since February 2026, Claude Mythos Preview has identified 1,596 vulnerabilities across 281 open-source software projects. Working with six external security research firms, Anthropic has triaged and responsibly disclosed these findings to maintainers, with 97 vulnerabilities already patched and 88 assigned official CVE or GitHub Security Advisory records.
The dashboard represents a significant demonstration of AI applied to cybersecurity, combining Claude's automated vulnerability detection with rigorous human expert review and responsible disclosure practices. Anthropic emphasizes that the disclosed vulnerabilities represent only a portion of what Claude Mythos Preview has identified, as human review and triage remain the limiting factor in their workflow. The initiative illustrates how advanced language models can contribute to open-source software security through systematic, transparent, and ethically-grounded vulnerability reporting.
