Researchers at Snyk disclosed four "Leaky Vessels" vulnerabilities affecting container runtimes and build tooling — notably runC (CVE-2024-21626, CVSS 8.6) and three BuildKit flaws (CVE-2024-23651, CVE-2024-23653, CVE-2024-23652) — that can enable container escape and arbitrary host file deletion; the issues are easy to exploit given local build/run access but require the ability to run or build containers on the target, and organizations are urged to apply vendor fixes promptly due to the widespread use of these components.
