A flaw was found in golang. Calling Unmarshal on an XML document into a Go struct, which has a nested field that uses the "any" field tag, can cause a panic due to stack exhaustion.

Other sources

Calling Unmarshal on a XML document into a Go struct which has a nested field that uses the any field tag can cause a panic due to stack exhaustion.

— Red Hat

Golang Go is vulnerable to a denial of service, caused by an uncontrolled recursion flaw in Unmarshal in encoding/xml due to stack exhaustion. By parsing a specially-crafted XML document, a remote attacker could exploit this vulnerability to cause a panic.

— IBM

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.
