From 3.0.0 until 3.2.5, 4.1.8, and 5.0.0-beta.4, Vitest Browser Mode exposed a cdp() API that forwarded raw Chrome DevTools Protocol methods without being gated by allowWrite or allowExec, allowing a remote client with exposed browser API metadata to use CDP Page.setDownloadBehavior and Runtime.evaluate to overwrite vite.config.ts and execute attacker-controlled Node.js code. This issue is fixed in versions 3.2.5, 4.1.8, and 5.0.0-beta.","state":0,"publishedAt":"2026-07-14T19:35:42.739+00:00","modifiedAt":"2026-07-29T18:26:18.528+00:00","affected":[{"ecosystem":"Vendor product","name":"vitest","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"vitest-dev\",\n                    \"product\": \"vitest\",\n                    \"versions\": [\n                        {\n                            \"version\": \">= 3.0.0, < 3.2.5\",\n                            \"status\": \"affected\"\n                        },\n                        {\n                            \"version\": \">= 4.0.0, < 4.1.8\",\n                            \"status\": \"affected\"\n                        },\n                        {\n                            \"version\": \">= 5.0.0-beta.0, < 5.0.0-beta.4\",\n                            \"status\": \"affected\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","score":9.8,"severity":"CRITICAL"}],"references":["https://github.com/vitest-dev/vitest/security/advisories/GHSA-g8mr-85jm-7xhm","https://github.com/vitest-dev/vitest/pull/10444","https://github.com/vitest-dev/vitest/pull/10450","https://github.com/vitest-dev/vitest/pull/10456","https://github.com/vitest-dev/vitest/commit/385a1aefd4c2bfa5e7d58bf7c6834c929969f2c7","https://github.com/vitest-dev/vitest/commit/63e3b2eee4d58da56786a6333f517b9b492528c7","https://github.com/vitest-dev/vitest/commit/e4067b3b150005fd42cf75f994300119245806b9","https://github.com/vitest-dev/vitest/releases/tag/v3.2.5","https://github.com/vitest-dev/vitest/releases/tag/v4.1.8","https://github.com/vitest-dev/vitest/releases/tag/v5.0.0-beta.4"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-53633","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-53633","identifiers":["CVE-2026-53633"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
