All the vulnerabilities related to the version 3.6.2 of the package
Regular Expression Denial of Service in marked
Affected versions of marked are vulnerable to Regular Expression Denial of Service (ReDoS). The _label subrule may significantly degrade parsing performance of malformed input.
Upgrade to version 0.7.0 or later.
Inefficient Regular Expression Complexity in marked
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.
Has the problem been patched?
Yes
What versions should users upgrade to?
4.0.10
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.
Are there any links users can visit to find out more?

TaffyDB can allow access to any data items in the DB
TaffyDB allows attackers to forge adding additional properties into user-input processed by taffy which can allow access to any data items in the DB. Taffy sets an internal index for each data item in its DB. However, it is found that the internal index can be forged by adding additional properties into user-input. If index is found in the query, TaffyDB will ignore other query conditions and directly return the indexed data item. Moreover, the internal index is in an easily-guessable format (e.g., T000002R000001). As such, attackers can use this vulnerability to access any data items in the DB. Note: taffy and its successor package taffydb are not maintained.
Arbitrary Code Execution in underscore
The package underscore from 1.13.0-0 and before 1.13.0-2, from 1.3.2 and before 1.12.1 are vulnerable to Arbitrary Code Execution via the template function, particularly when a variable property is passed as an argument as it is not sanitized.
Uncontrolled Resource Consumption in markdown-it
Special patterns with length > 50K chars can slow down parser significantly.
const md = require('markdown-it')();
md.render(`x ${' '.repeat(150000)} x \nx`);
Upgrade to v12.3.2+
No.
