When a full CVSS v2.0 vector string is parsed using ParseVector, an Out-of-Bounds Read is possible due to a lack of tests. The Go module will then panic.
The problem is patched in tag v0.4.0, by the commit d9d478ff0c13b8b09ace030db9262f3c2fe031f4.
The only way to avoid it is by parsing CVSS v2.0 vector strings that does not have all attributes defined (e.g. AV:N/AC:L/Au:N/C:P/I:P/A:C/E:U/RL:OF/RC:C/CDP:MH/TD:H/CR:M/IR:M/AR:M).

As stated in SECURITY.md, the CPE v2.3 to refer to this Go module is cpe:2.3:a:pandatix:go_cvss:*:*:*:*:*:*:*:*.
The entry has already been requested to the NVD CPE dictionnary.
package main
import (
"log"
gocvss20 "github.com/pandatix/go-cvss/20"
)
func main() {
_, err := gocvss20.ParseVector("AV:N/AC:L/Au:N/C:P/I:P/A:C/E:U/RL:OF/RC:C/CDP:MH/TD:H/CR:M/IR:M/AR:M")
if err != nil {
log.Fatal(err)
}
}
When ran, the following trace is returned.
