{"id":"CVE-2026-54753","aliases":["GHSA-g2r8-wvmj-jf5w"],"url":"https://o3.security/vulnerability/CVE-2026-54753","summary":"Nx: `nx graph` dev server permissive CORS policy","details":"Nx is a monorepo solution for TypeScript and polyglot codebases. From 17.0.4 until 22.7.2 and 23.0.0-beta.2, the local HTTP server started by nx graph sent Access-Control-Allow-Origin: * on every response, letting any website a developer visited read the server's responses cross-origin — including the full project graph and the output of the /help endpoint, which runs a target's configured help command. The practical impact is typically cross-origin information disclosure, but can be arbitrary command injection in rare cases. This vulnerability is fixed in 22.7.2 and 23.0.0-beta.2.","published":"2026-06-26T18:13:34.371Z","modified":"2026-08-12T03:51:17.994717725Z","cvss":{"score":5.9,"severity":"MEDIUM","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:R/S:U/C:H/I:L/A:N"},"epss":{"score":0.01204,"percentile":0.66758,"asOf":"2026-09-17"},"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"npm","name":"nx","fixedVersion":"22.7.2"},{"ecosystem":"npm","name":"nx","fixedVersion":"23.0.0-beta.2"}],"fix":{"url":"https://github.com/nrwl/nx/pull/35494","label":"nrwl/nx#35494"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/54xxx/CVE-2026-54753.json"},{"type":"ADVISORY","url":"https://github.com/nrwl/nx/security/advisories/GHSA-g2r8-wvmj-jf5w"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-54753"},{"type":"FIX","url":"https://github.com/nrwl/nx/pull/35494"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-12T03:51:17.994717725Z"}}
