CVE-2021-37579
But there's an exception that the attacker can use to skip the security check (when enabled) and reaching a deserialization operation with native java serialization.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (6.56%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
