Description

Unmarshaling an XML document into a Go struct which has a nested field that uses the 'any' field tag can panic due to stack exhaustion.

NVD description

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.
