Thank you for sharing this with oss-security!

There's now also a disclosure by Cyata, the researchers who found these
issues:
https://cyata.ai/blog/exploiting-a-full-chain-of-trust-flaws-how-we-went-from-unauthenticated-to-arbitrary-remote-code-execution-rce-in-cyberark-conjur/

They also looked for and found logic flaws in HashiCorp Vault, but I am
hoping we'll have a separate thread on that (I am asking them to post).

Meanwhile, attached is a plain text export of the above blog post.
