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.","status":"published","published":"2022-01-14T17:15:13.27Z","modified":"2026-11-03T06:01:12.548028172Z","updated_at":"2026-11-03T06:44:26.638603Z"},{"id":"ROOT-APP-NPM-CVE-2022-21681","title":"CVE-2022-21681 in marked - Patched by Root","description":"Root has patched CVE-2022-21681 in the marked package for Root:npm.
