Epoch AI 分析：Claude Mythos Preview 公布后高危 CVE 数量升至此前月度纪录 3.5 倍以上

In April 2026, Anthropic announced that its latest internal model (Claude Mythos Preview) was capable of autonomous cybersecurity vulnerability discovery and exploitation. Since then, both Anthropic and OpenAI have launched efforts to use frontier models to harden critical software before malicious actors are able to use the same models for harm.

We show that the number of Common Vulnerabilities and Exposures (CVEs) jumped significantly following these announcements. Compared to the previous monthly record before the Mythos Preview announcement, the number of high- and critical-severity vulnerabilities increased more than 3.5x in June.

Data

Our Cyber Vulnerability Reports hub visualizes data from cve.org, a public repository of CVE reports from software companies and third-party security researchers. We focus our analysis on CVEs reported by 21 notable organizations to avoid capturing noisy submissions from less reputable sources. These notable organizations include:

Microsoft · Google · Apple · Adobe · Oracle · Cisco · IBM · Red Hat · Intel · AMD · NVIDIA · Qualcomm · Samsung · SAP · Amazon (AWS) · VMware (Broadcom) · GitHub (own products) · Linux · Mozilla · Apache · OpenSSL

Assumptions and limitations

Our figures come from publicly disclosed vulnerabilities, which do not include discovered but not publicly disclosed vulnerabilities. Anthropic claims that their Project Glasswing alone has identified over 10,000 high- and critical-severity vulnerabilities.

While some of the increase in observed vulnerability disclosure is almost certainly due to increased feasibility of discovery, the spike may also be caused in part by an increase in the amount of interest in discovering bugs.
