Last modified Jun 17, 2026

CVE-2019-11480 is a high-severity vulnerability rated 8.1/10 on the CVSS scale. The pc-kernel snap build process hardcoded the --allow-insecure-repositories and --allow-unauthenticated apt options when creating the build chroot environment. This could allow an attacker who is able to perform a MITM attack between the build environment and the Ubuntu archive to install a malicious package within the build chroot. EPSS estimates a 0.51% chance of exploitation in the next 30 days.
