{"cve":"CVE-2025-48888","nvd":{"published":"2025-06-04T20:15:23.977","modified":"2026-06-17T09:30:26.283","status":"Analyzed","description":"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.","cvss_v4":{"vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:L/VA:N/SC:N/SI:N/SA:N/E:P","score":5.5},"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:N","score":5.3},"cwes":["CWE-863"],"references":["https://github.com/denoland/deno/commit/2f0fae9d9071dcaf0a689bc7097584b1b9ebc8db","https://github.com/denoland/deno/commit/9d665572d3cd39f997e29e6daac7c1102fc5c04f","https://github.com/denoland/deno/commit/ef315b56c26c9ef5f25284a5100d2ed525a148cf","https://github.com/denoland/deno/pull/22894","https://github.com/denoland/deno/pull/29213"],"products":["deno:deno"],"source":"nvd","synced_at":"2026-10-19T22:02:23.998251710+00:00"},"epss":{"cve":"CVE-2025-48888","score":0.00423,"percentile":0.3665,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-xqxc-x6p3-w683","url":"https://osv.dev/vulnerability/GHSA-xqxc-x6p3-w683","summary":"Deno run with --allow-read and --deny-read flags results in allowed","modified":"2026-09-10T03:50:25.589182092Z","packages":[{"ecosystem":"crates.io","name":"deno","purl":"pkg:cargo/deno","ranges":[">=1.41.3 <2.1.13"],"fixed":["2.1.13"]},{"ecosystem":"crates.io","name":"deno","purl":"pkg:cargo/deno","ranges":[">=2.2.0 <2.2.13"],"fixed":["2.2.13"]},{"ecosystem":"crates.io","name":"deno","purl":"pkg:cargo/deno","ranges":[">=2.3.0 <2.3.2"],"fixed":["2.3.2"]},{"ecosystem":"crates.io","name":"deno_runtime","purl":"pkg:cargo/deno_runtime","ranges":[">=0.150.0 <0.212.0"],"fixed":["0.212.0"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
