{"id":"CVE-2024-49770","aliases":["GHSA-qm92-93fv-vh7m"],"url":"https://o3.security/vulnerability/CVE-2024-49770","summary":"oak's path traversal allows transfer of hidden files within the served root directory","details":"`oak` is a middleware framework for Deno's native HTTP server, Deno Deploy, Node.js 16.5 and later, Cloudflare Workers and Bun. By default `oak` does not allow transferring of hidden files with `Context.send` API. However, prior to version 17.1.3, this can be bypassed by encoding `/` as its URL encoded form `%2F`. For an attacker this has potential to read sensitive user data or to gain access to server secrets. Version 17.1.3 fixes the issue.","published":"2024-11-01T16:16:29.482Z","modified":"2026-07-15T01:48:56.383780143Z","cvss":null,"epss":null,"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"npm","name":"@oakserver/oak","fixedVersion":null}],"fix":{"url":"https://github.com/oakserver/oak/commit/4b2f27efd5cba5a45b2c3982e610da3af0869209","label":"oakserver/oak@4b2f27e"},"references":[{"type":"WEB","url":"https://github.com/oakserver/oak/blob/3896fe568b25ac0b4c5afbf822ff8344c3d1712a/send.ts#L117-L125"},{"type":"WEB","url":"https://github.com/oakserver/oak/blob/3896fe568b25ac0b4c5afbf822ff8344c3d1712a/send.ts#L182C10-L182C25"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2024/49xxx/CVE-2024-49770.json"},{"type":"ADVISORY","url":"https://github.com/oakserver/oak/security/advisories/GHSA-qm92-93fv-vh7m"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2024-49770"},{"type":"FIX","url":"https://github.com/oakserver/oak/commit/4b2f27efd5cba5a45b2c3982e610da3af0869209"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-07-15T01:48:56.383780143Z"}}
