There is no fixed version for Debian:10 node-marked.

NVD Description

Note: Versions mentioned in the description apply only to the upstream node-marked package and not the node-marked package as distributed by Debian. See How to fix? for Debian:10 relevant fixed versions and status.

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.
