Anthropic's coordinated vulnerability disclosure dashboard Overview · Ledger · Archive · About Light Dark System Last updated 2026-05-22 10:27 PT. In February 2026, Anthropic began using an early snapshot of Claude Mythos Preview to find security vulnerabilities in open-source software. We then partnered with external security research firms to triage findings, validate them, and report human-reviewed critical- or high-severity vulnerabilities to the software's maintainers under our Coordinated Vulnerability Disclosure policy. This page tracks the findings that we've disclosed, and, in line with our policy, publishes details of the ones whose disclosure window has now closed. As of May 22, 2026, we've disclosed 1,596 vulnerabilities across 281 open source projects.
