{"id":"CVE-2025-48888","aliases":["GHSA-xqxc-x6p3-w683"],"url":"https://o3.security/vulnerability/CVE-2025-48888","summary":"Deno run with --allow-read and --deny-read flags results in allowed","details":"Deno is a JavaScript, TypeScript, and WebAssembly runtime. Starting in version 1.41.3 and prior to versions 2.1.13, 2.2.13, and 2.3.2, `deno run --allow-read --deny-read main.ts` results in allowed, even though 'deny' should be stronger. The result is the same with all global unary permissions given as `--allow-* --deny-*`. This only affects a nonsensical combination of flags, so there shouldn't be a real impact on the userbase. Users may upgrade to version 2.1.13, 2.2.13, or 2.3.2 to receive a patch.","published":"2025-06-04T19:15:55.041Z","modified":"2026-08-12T03:51:14.427494883Z","cvss":null,"epss":null,"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"crates.io","name":"deno","fixedVersion":"2.1.13"},{"ecosystem":"crates.io","name":"deno","fixedVersion":"2.2.13"},{"ecosystem":"crates.io","name":"deno","fixedVersion":"2.3.2"},{"ecosystem":"crates.io","name":"deno_runtime","fixedVersion":"0.212.0"}],"fix":{"url":"https://github.com/denoland/deno/commit/2f0fae9d9071dcaf0a689bc7097584b1b9ebc8db","label":"denoland/deno@2f0fae9"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2025/48xxx/CVE-2025-48888.json"},{"type":"ADVISORY","url":"https://github.com/denoland/deno/security/advisories/GHSA-xqxc-x6p3-w683"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2025-48888"},{"type":"FIX","url":"https://github.com/denoland/deno/commit/2f0fae9d9071dcaf0a689bc7097584b1b9ebc8db"},{"type":"FIX","url":"https://github.com/denoland/deno/commit/9d665572d3cd39f997e29e6daac7c1102fc5c04f"},{"type":"FIX","url":"https://github.com/denoland/deno/commit/ef315b56c26c9ef5f25284a5100d2ed525a148cf"},{"type":"FIX","url":"https://github.com/denoland/deno/pull/22894"},{"type":"FIX","url":"https://github.com/denoland/deno/pull/29213"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-12T03:51:14.427494883Z"}}
