      "value": "Marked is a markdown parser and compiler. 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."

Como medida de mitigaci\u00f3n, evite ejecutar markdown no confiable mediante marked o ejecute marked en un hilo de trabajo y establezca un l\u00edmite de tiempo razonable para evitar el agotamiento de los recursos"
