Three Critical Buffer Overflow Vulnerabilities Disclosed in Hashcat — Penetration Testing Toolchain at Risk

Security researchers have disclosed three buffer overflow vulnerabilities (CVE-2026-42482, CVE-2026-42483, CVE-2026-42484) in Hashcat, the widely-used open-source password recovery and penetration testing tool. The flaws can be triggered via maliciously crafted hash files or wordlists and may allow code execution in environments where Hashcat processes untrusted input — including shared red team infrastructure and automated password auditing pipelines.
