CVE-2021-41091 is a medium-severity vulnerability in Moby (Docker Engine) affecting Fedora and Moby products. It allows unprivileged Linux users on the host to traverse container data directories, discover and execute programs with extended permissions (like setuid), and potentially read or modify container files due to UID collisions. The vulnerability has a CVSS score of 6.3, indicating a local attack vector with low complexity, leading to potential low impact on confidentiality, integrity, and availability. There is no evidence of active exploitation, public exploit code (Metasploit, Nuclei, ExploitDB), or significant community discussion or media coverage. Users are advised to update to Moby 20.10.9 and restart containers, or implement host access and volume restrictions if unable to upgrade.
