Anthropic has launched a coordinated vulnerability disclosure dashboard, revealing 1,596 vulnerabilities across 281 open-source projects as of May 22, 2026. The vulnerabilities were identified using the Claude Mythos Preview tool, with 97 confirmed patched and 88 assigned CVE or GHSA identifiers. The dashboard emphasizes that the disclosed vulnerabilities represent a subset of total findings, as human triage is the limiting factor in reporting. Project names and bug types are withheld until maintainers release fixes, ensuring a collaborative relationship with developers. The dashboard aims to improve transparency in open-source security by tracking remediation progress and providing visibility into the volume of discovered vulnerabilities.
