Anthropic's OSS Scanner Flags 29,000 Vulnerabilities, Including Critical Curl Flaw On October 8, 2026, Anthropic launched its free OSS Scanner, which has identified 29,439 potential vulnerabilities in open-source software since November 2025. Among these, a serious flaw in the curl project was highlighted by maintainer Daniel Stenberg as one of the worst in years. The scanner operates without human review, meaning reports may contain inaccuracies. As of October 2, 2026, external security firms had reviewed 6,123 of the flagged vulnerabilities, resulting in 584 security advisories. The initiative aims to enhance security for critical infrastructure operators, including partners like CrowdStrike and Palo Alto Networks. However, nearly 5,000 unverified reports were sent directly to maintainers, raising concerns about the reliability of the findings. The program reflects lessons learned from previous efforts that failed to reduce cyber risk effectively. 4 sources 51
