Marked is a markdown parser and compiler. Prior to version 4.0.10, the
regular expression block.def
may cause catastrophic backtracking against
some strings and lead to a regular expression denial of service (ReDoS).
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.
