Trivy's own label is CRITICAL. Rated critical by NVD. Rated lower by GHSA (high), Ubuntu (medium).

Description

OctoRPKI does not escape a URI with a filename containing "..", this allows a repository to create a file, (ex. rsync://example.org/repo/../../etc/cron.daily/evil.roa), which would then be written to disk outside the base cache folder. This could allow for remote code execution on the host machine OctoRPKI is running on.
