CVE-2018-10856

25
FAUCET Score

CVE-2018-10856 describes a privilege escalation vulnerability in Podman versions prior to 0.6.1, where containers executed by non-root users retain unnecessary capabilities, granting them elevated privileges. This high-severity flaw (CVSS 8.8) is easily exploitable over the network with low privileges and no user interaction, potentially leading to complete compromise of confidentiality, integrity, and availability. Despite its severity, there is no evidence of active exploitation, public exploit code, or significant community discussion surrounding this vulnerability.
