Details
As written in the advisory (Markdown source, shown as plain text).
### Impact
When copying files with rsync, octorpki uses the "-a" flag 0, which forces rsync to copy binaries with the suid bit set as root. Since the provided service definition defaults to root (https://github.com/cloudflare/cfrpki/blob/master/package/octorpki.service) this could allow for a vector, when combined with another vulnerability that causes octorpki to process a malicious TAL file, for a local privilege escalation.
