{"id":"GHSA-886v-mm6p-4m66","summary":"High severity vulnerability that affects gun","details":"## Urgent Upgrade\n\nThe static file server module included with GUN had a **serious vulnerability**:\n\n - Using `curl --path-as-is` allowed reads on any parent directory or files.\n\nThis did not work via the browser or via curl without as-is option.\n\n ### Fixed\n\nThis has been fixed since version `0.2019.416` and higher.\n\n ### Who Was Effected?\n\nMost NodeJS users who use the default setup, such as:\n\n - `npm start`\n - `node examples/http.js`\n - `Heroku` 1-click-deploy\n - `Docker`\n - `Now`\n\nIf you have a custom NodeJS code then you are probably safe *unless* you have something like `require('http').createServer(Gun.serve(__dirname))` in it.\n\nIf you have not upgraded, it is **mandatory** or else it is highly likely your environment variables and AWS (or other) keys could be leaked.\n\n ### Credit\n\nIt was reported and fixed by [JK0N](https://github.com/amark/gun/pull/527), but I did not understand the `--path-as-is` condition.\n\nJoonas Loppi from [function61](http://function61.com) rediscovered it and explained the urgency to me to fix it.\n","modified":"2021-09-07T15:24:35Z","published":"2019-06-05T09:48:02Z","database_specific":{"nvd_published_at":null,"cwe_ids":["CWE-22"],"severity":"HIGH","github_reviewed":true,"github_reviewed_at":"2020-06-16T21:24:52Z"},"references":[{"type":"WEB","url":"https://github.com/amark/gun/security/advisories/GHSA-886v-mm6p-4m66"},{"type":"ADVISORY","url":"https://github.com/advisories/GHSA-886v-mm6p-4m66"},{"type":"PACKAGE","url":"https://github.com/amark/gun"}],"affected":[{"package":{"name":"gun","ecosystem":"npm","purl":"pkg:npm/gun"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0"},{"fixed":"0.2019.416"}]}],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2019/06/GHSA-886v-mm6p-4m66/GHSA-886v-mm6p-4m66.json"}}],"schema_version":"1.9.0"}
