CVE-2026-42306
Last modified
CVE-2026-42306 is a high-severity vulnerability rated 7.2/10 on the CVSS scale. Moby is an open source container framework. In Docker Engine prior to version 29.5.1, Docker Daemon versions 28.5.2 and prior, and Moby Daemon prior to version 2.0.0-beta.14, a race condition during docker cp mount setup allows a malicious container to redirect a bind mount target to an arbitrary host path, potentially overwriting host files or causing denial of service. EPSS estimates a 0.10% chance of exploitation in the next 30 days.
