CVE-2022-3616
Attackers can create long chains of CAs that would lead to OctoRPKI exceeding its max iterations parameter.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (0.43%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
