CVE-2022-30633
Uncontrolled recursion in Unmarshal in encoding/xml before Go 1.17.12 and Go 1.18.4 allows an attacker to cause a panic due to stack exhaustion via unmarshalling an XML document into a Go struct which has a nested field that uses the 'any' field tag.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (1.96%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
