  "account": "Anthropic's super bug-hunting model, Mythos, has demonstrated exceptional mathematical prowess in uncovering a critical vulnerability in the Rejetto HTTP File Server (HFS). Initially discovered by Chinese-based attackers, the authentication-bypass bug grants full admin access and enables remote code execution. HFS, an open-source web file server, had previously appeared on the US Cybersecurity and Infrastructure Security Agency’s list of Known Exploited Vulnerabilities. In response, researchers from AI pen-testing company Horizon3 utilized Mythos to identify a new flaw in HFS, now tracked as CVE-2026-61500. Upon learning of the vulnerability, Horizon3's researchers promptly updated HFS to version 3.2.1 or later, which addresses the security flaw.",
