3 Security Vulnerabilities

Inefficient Regular Expression Complexity in marked

Published date: 2022-01-14T21:04:46Z
CVE: CVE-2022-21681
Links:

Impact

What kind of vulnerability is it?

Denial of service.

The regular expression inline.reflinkSearch may cause catastrophic backtracking against some strings. PoC is the following.

import * as marked from 'marked';

console.log(marked.parse(`[x]: x

\\[\\](\\[\\](\\[\\](\\[\\](\\[\\](\\[\\](\\[\\](\\[\\](\\[\\](\\[\\](\\[\\](\\[\\](\\[\\](\\[\\](\\[\\](\\[\\](\\[\\](\\[\\](\\[\\](\\[\\](\\[\\](\\[\\](\\[\\](\\[\\](\\[\\](\\[\\](\\[\\](\\[\\](\\[\\](\\[\\](`));

Who is impacted?

Anyone who runs untrusted markdown through marked and does not use a worker with a time limit.

Patches

Has the problem been patched?

Yes

What versions should users upgrade to?

4.0.10

Workarounds

Is there a way for users to fix or remediate the vulnerability without upgrading?

Do not run untrusted markdown through marked or run marked on a worker thread and set a reasonable time limit to prevent draining resources.

Marked ReDoS due to email addresses being evaluated in quadratic time

Published date: 2019-06-05T14:10:03Z
Links:

Versions of marked from 0.3.14 until 0.6.2 are vulnerable to Regular Expression Denial of Service. Email addresses may be evaluated in quadratic time, allowing attackers to potentially crash the node process due to resource exhaustion.

Recommendation

Upgrade to version 0.6.2 or later.

Affected versions: ["0.3.14", "0.3.15", "0.3.16", "0.3.17", "0.3.18", "0.3.19", "0.4.0", "0.5.0", "0.5.1", "0.5.2", "0.6.0", "0.6.1"]
