GitHub Vulnerability Alerts

GHSA-ch52-vgq2-943f

Affected versions of marked are vulnerable to Regular Expression Denial of Service (ReDoS). The _label subrule may significantly degrade parsing performance of malformed input.

Recommendation

Upgrade to version 0.7.0 or later.

CVE-2022-21680

Impact

What kind of vulnerability is it?

Denial of service.

The regular expression block.def may cause catastrophic backtracking against some strings.
PoC is the following.

import * as marked from "marked";

marked.parse(`[x]:${' '.repeat(1500)}x ${' '.repeat(1500)} 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.
