CVE-2026-16487 (GCVE-0-2026-16487)
Vulnerability from cvelistv5

Red Hat Product Security has determined that this is not a vulnerability in bootc or containers-common. bootc fetches images under /etc/containers/policy.json. The shipped default is insecureAcceptAnything for registries without an explicit signature requirement; registry.redhat.io and registry.access.redhat.com require signatures. Updating a mutable tag requires the ability to publish to the reference an administrator has already configured the host to follow. Requiring signatures is available through that policy and through bootc enforce-container-sigpolicy, which is off by default. Persistence of /var across bootc rollback is expected image-mode behavior.
