[![🚨 This automated pull request was created by Frogbot and fixes the below:](https://raw.githubusercontent.com/jfrog/frogbot/master/resources/v2/vulnerabilitiesFixBannerPR.png)](https://docs.jfrog-applications.jfrog.io/jfrog-applications/frogbot)
Description:
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.
