Anthropic says Project Glasswing partners uncovered at least 129,000 verified software vulnerabilities between April and July 2026 and its own scanning found 5,500 more between April and October 2026; of these together, more than 33,000 have so far been rated critical- or high-severity, a figure based on survey data from a subset of partners.

The exact words it rests on

our partners uncovered at least 129,000 verified software vulnerabilities between April and July 2026. And through our own open-source scanning efforts, we found an additional 5,500 verified software vulnerabilities between April and October 2026. Of these verified vulnerabilities, more than 33,000 have so far been rated as critical- or high-severity. This is likely an undercount, as it is based on survey data from only a subset of Glasswing partners.
