go-cvss is a Go module to manipulate Common Vulnerability Scoring System (CVSS). In affected versions 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`. Users are advised to upgrade. Users unable to upgrade may avoid this issue by parsing only CVSS v2.0 vector strings that do 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`).
