CVE-2022-21680

Cubic catastrophic backtracking (ReDoS) in marked

Published: Jan 14, 2022Updated: Nov 21, 2024 Sources: CVE List NVD GHSA BDUCWE-400

Description

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.
