Anthropic launches free OSS Scanner for open-source vulnerabilities

Anthropic launched OSS Scanner, a free, opt-in service that runs its strongest models, including Claude Mythos, against enrolled critical open-source projects. Reports go directly to maintainers without human review.

Why it matters: Skipping human review speeds findings but moves triage onto often volunteer maintainers, who may face a flood of reports. It also follows recent cases of AI models finding serious flaws, such as the PHP bug, and marks vendors shifting from demos to routine defensive scanning.
