Prior to version 4.0.10, the regular expression `inline.reflinkSearch` may cause catastrophic backtracking against some strings and lead to a denial of service (DoS). Anyone who runs untrusted markdown through a vulnerable version of marked and does not use a worker with a time limit may be affected. This issue is patched in version 4.0.10. As a workaround, avoid running untrusted markdown through marked or run marked on a worker thread and set a reasonable time limit to prevent draining resources."}],"affected":[{"vendor":"markedjs","product":"marked","versions":[{"version":"< 4.0.10","status":"affected"}]}],"references":[{"url":"https://github.com/markedjs/marked/security/advisories/GHSA-5v2h-r2cx-5xgj"},{"url":"https://github.com/markedjs/marked/commit/8f806573a3f6c6b7a39b8cdb66ab5ebb8d55a5f5"},{"name":"FEDORA-2022-784d729f30","tags":["vendor-advisory"],"url":"https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/AIXDMC3CSHYW3YWVSQOXAWLUYQHAO5UX/"}],"metrics":[{"cvssV3_1":{"version":"3.1","vectorString":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","attackVector":"NETWORK","attackComplexity":"LOW","privilegesRequired":"NONE","userInteraction":"NONE","scope":"UNCHANGED","confidentialityImpact":"NONE","integrityImpact":"NONE","availabilityImpact":"HIGH","baseScore":7.5,"baseSeverity":"HIGH"}}],"problemTypes":[{"descriptions":[{"type":"CWE","lang":"en","description":"CWE-400: Uncontrolled Resource Consumption","cweId":"CWE-400"}]},{"descriptions":[{"type":"CWE","lang":"en","description":"CWE-1333: Inefficient Regular Expression Complexity","cweId":"CWE-1333"}]}],"source":{"advisory":"GHSA-5v2h-r2cx-5xgj","discovery":"UNKNOWN"}},"adp":[{"providerMetadata":{"orgId":"af854a3a-2127-422b-91ae-364da2661108","shortName":"CVE","dateUpdated":"2024-08-03T02:46:39.337Z"},"title":"CVE Program Container","references":[{"url":"https://github.com/markedjs/marked/security/advisories/GHSA-5v2h-r2cx-5xgj","tags":["x_transferred"]},{"url":"https://github.com/markedjs/marked/commit/8f806573a3f6c6b7a39b8cdb66ab5ebb8d55a5f5","tags":["x_transferred"]},{"name":"FEDORA-2022-784d729f30","tags":["vendor-advisory","x_transferred"],"url":"https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/AIXDMC3CSHYW3YWVSQOXAWLUYQHAO5UX/"}]},{"metrics":[{"other":{"type":"ssvc","content":{"timestamp":"2025-04-22T15:42:21.459933Z","id":"CVE-2022-21681","options":[{"Exploitation":"poc"},{"Automatable":"yes"},{"Technical Impact":"partial"}],"role":"CISA Coordinator","version":"2.0.3"}}}],"title":"CISA ADP Vulnrichment","providerMetadata":{"orgId":"134c704f-9b21-4f2e-91b3-4a467353bcc0","shortName":"CISA-ADP","dateUpdated":"2025-04-22T18:33:29.916Z"}}]}}
