Anthropic says its Claude Mythos model discovered thousands of severe vulnerabilities across more than 1,000 open source software (OSS) projects.<\/strong><\/p>\n

According to the AI giant, Mythos Preview has identified more than 23,000 potential vulnerabilities. Of these, 1,900 have been reviewed by external security firms, and 1,726 have been confirmed, including over 1,000 rated \u2018high\u2019 or \u2018critical\u2019 severity.<\/p>\n

The findings are still being reviewed, and Anthropic estimates that nearly 3,900 critical and high-severity vulnerabilities will be confirmed based only on current findings. As the scans are ongoing, the company believes the number of severe vulnerabilities may reach 6,200.<\/p>\n

Anthropic says more than 1,100 unverified findings have been reported to vendors, and 75 issues with a critical or high severity rating have been patched. Vendors have published 65 security advisories.<\/p>\n

\u201cThe number of patches is still relatively low for three reasons. First, we\u2019re still early in the 90-day window that\u2019s set out in our Coordinated Vulnerability Disclosure policy: we expect many more patches to land soon,\u201d the AI company explained.\u00a0<\/p>\n

\u201cSecond, we are likely to be undercounting patches because some vulnerabilities are patched without a public advisory: in those cases, we\u2019re reliant on scanning for the patches ourselves using Claude. Third, the low volume of patches reflects a genuine problem: even at our relatively slow pace of disclosures, Mythos Preview is adding to an already-overloaded security ecosystem,\u201d it added.<\/p>\n

In response to the surge in AI-powered vulnerability discovery, Anthropic recently unveiled Claude Security, a codebase scanner designed to help developers find security issues in their applications.\u00a0<\/p>\n

The vulnerabilities described in Anthropic\u2019s new report are limited to OSS projects, with much of the scanning conducted…<\/p>\n
