{"id":"CVE-2024-27932","aliases":["GHSA-5frw-4rwq-xhcr"],"url":"https://o3.security/vulnerability/CVE-2024-27932","summary":"Deno's improper suffix match testing for DENO_AUTH_TOKENS","details":"Deno is a JavaScript, TypeScript, and WebAssembly runtime. Starting in version 1.8.0 and prior to version 1.40.4, Deno improperly checks that an import specifier's hostname is equal to or a child of a token's hostname, which can cause tokens to be sent to servers they shouldn't be sent to. An auth token intended for `example[.]com` may be sent to `notexample[.]com`. Anyone who uses DENO_AUTH_TOKENS and imports potentially untrusted code is affected. Version 1.40.0 contains a patch for this issue","published":"2024-03-06T20:45:16.373Z","modified":"2026-08-07T11:49:24.023290959Z","cvss":{"score":4.6,"severity":"MEDIUM","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:U/C:L/I:L/A:N"},"epss":null,"cisaKev":null,"exploitsKnown":1,"affectedPackages":[{"ecosystem":"crates.io","name":"deno","fixedVersion":"1.40.4"}],"fix":{"url":"https://github.com/denoland/deno/commit/de23e3b60b066481cc390f459497d5bef42a899b","label":"denoland/deno@de23e3b"},"references":[{"type":"WEB","url":"https://github.com/denoland/deno/blob/3f4639c330a31741b0efda2f93ebbb833f4f95bc/cli/auth_tokens.rs#L89"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2024/27xxx/CVE-2024-27932.json"},{"type":"ADVISORY","url":"https://github.com/denoland/deno/security/advisories/GHSA-5frw-4rwq-xhcr"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2024-27932"},{"type":"FIX","url":"https://github.com/denoland/deno/commit/de23e3b60b066481cc390f459497d5bef42a899b"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-07T11:49:24.023290959Z"}}
