CVE-2022-21680 not yet assigned priority: Debian including 1 source packages (node-marked), 5 status rows across 5 suites (bookworm, bullseye, forky, sid, trixie): resolved 4, open 1.
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.
