CVE-2021-3907 is fixed in 2 products on 1 platform, first by DEBIAN-CVE-2021-3907, released November 11, 2021. It is not reported as exploited. Patch Radar priority: Urgent.
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.
