Lint-staged version 0.1.0 marks the initial release of a tool designed to streamline the linting process in Git-based workflows. This early iteration focuses on automatically linting JavaScript and CSS files that are staged for commit, ensuring code quality and consistency from the outset. Developers using this version benefit from automated checks performed by popular linters ESLint and Stylelint. The documented dependencies ensure that these linters, specifically ESLint version 1.10.3 and Stylelint version 3.2.2, are compatible and used for the linting process. Key dependencies also include staged-files version 0.1.2, responsible for efficiently identifying the relevant staged files that lint-staged then processes.
Transitioning from the previous (undefined) stable version, if one existed, to 0.1.0 introduces a functional linting solution, albeit in its foundational form. While the initial release laid the groundwork for automated linting of staged files, later releases likely expanded on features, performance, and configuration options. Developers should be aware that this initial version might lack the refinement and feature set found in later releases. For individuals seeking a basic and functional lint-staged, compatible with older ESLint and Stylelint versions, v0.1.0 provides a starting point. However, it's advisable to consider newer versions for improved features, greater efficiency, and ongoing support.
All the vulnerabilities related to the version 0.1.0 of the package
Denial of Service in js-yaml
Versions of js-yaml prior to 3.13.0 are vulnerable to Denial of Service. By parsing a carefully-crafted YAML file, the node process stalls and may exhaust system resources leading to a Denial of Service.
Upgrade to version 3.13.0.
Code Injection in js-yaml
Versions of js-yaml prior to 3.13.1 are vulnerable to Code Injection. The load() function may execute arbitrary code injected through a malicious YAML file. Objects that have toString as key, JavaScript code as value and are used as explicit mapping keys allow attackers to execute the supplied code through the load() function. The safeLoad() function is unaffected.
An example payload is
{ toString: !<tag:yaml.org,2002:js/function> 'function (){return Date.now()}' } : 1
which returns the object
{
"1553107949161": 1
}
Upgrade to version 3.13.1.
Improper Privilege Management in shelljs
shelljs is vulnerable to Improper Privilege Management
Improper Privilege Management in shelljs
Output from the synchronous version of shell.exec() may be visible to other users on the same system. You may be affected if you execute shell.exec() in multi-user Mac, Linux, or WSL environments, or if you execute shell.exec() as the root user.
Other shelljs functions (including the asynchronous version of shell.exec()) are not impacted.
Patched in shelljs 0.8.5
Recommended action is to upgrade to 0.8.5.

If you have any questions or comments about this advisory:
Prototype Pollution in lodash.merge
Versions of lodash.merge before 4.6.1 are vulnerable to Prototype Pollution. The function 'merge' may allow a malicious user to modify the prototype of Object via __proto__ causing the addition or modification of an existing property that will exist on all objects.
Update to version 4.6.1 or later.
Prototype Pollution in lodash.merge
Versions of lodash.merge before 4.6.2 are vulnerable to prototype pollution. The function merge may allow a malicious user to modify the prototype of Object via {constructor: {prototype: {...}}} causing the addition or modification of an existing property that will exist on all objects.
Update to version 4.6.2 or later.
Uncontrolled Resource Consumption in trim-newlines
@rkesters/gnuplot is an easy to use node module to draw charts using gnuplot and ps2pdf. The trim-newlines package before 3.0.1 and 4.x before 4.0.1 for Node.js has an issue related to regular expression denial-of-service (ReDoS) for the .end() method.
Prototype Pollution in lodash
Versions of lodash before 4.17.12 are vulnerable to Prototype Pollution. The function defaultsDeep allows a malicious user to modify the prototype of Object via {constructor: {prototype: {...}}} causing the addition or modification of an existing property that will exist on all objects.
Update to version 4.17.12 or later.
Prototype Pollution in lodash
Versions of lodash before 4.17.5 are vulnerable to prototype pollution.
The vulnerable functions are 'defaultsDeep', 'merge', and 'mergeWith' which allow a malicious user to modify the prototype of Object via __proto__ causing the addition or modification of an existing property that will exist on all objects.
Update to version 4.17.5 or later.
Prototype Pollution in lodash
Versions of lodash before 4.17.11 are vulnerable to prototype pollution.
The vulnerable functions are 'defaultsDeep', 'merge', and 'mergeWith' which allow a malicious user to modify the prototype of Object via {constructor: {prototype: {...}}} causing the addition or modification of an existing property that will exist on all objects.
Update to version 4.17.11 or later.
Regular Expression Denial of Service (ReDoS) in lodash
lodash prior to 4.7.11 is affected by: CWE-400: Uncontrolled Resource Consumption. The impact is: Denial of service. The component is: Date handler. The attack vector is: Attacker provides very long strings, which the library attempts to match using a regular expression. The fixed version is: 4.7.11.
Prototype Pollution in lodash
Versions of lodash prior to 4.17.19 are vulnerable to Prototype Pollution. The functions pick, set, setWith, update, updateWith, and zipObjectDeep allow a malicious user to modify the prototype of Object if the property identifiers are user-supplied. Being affected by this issue requires manipulating objects based on user-provided property values or arrays.
This vulnerability causes the addition or modification of an existing property that will exist on all objects and may lead to Denial of Service or Code Execution under specific circumstances.
Regular Expression Denial of Service (ReDoS) in lodash
All versions of package lodash prior to 4.17.21 are vulnerable to Regular Expression Denial of Service (ReDoS) via the toNumber, trim and trimEnd functions.
Steps to reproduce (provided by reporter Liyuan Chen):
var lo = require('lodash');
function build_blank(n) {
var ret = "1"
for (var i = 0; i < n; i++) {
ret += " "
}
return ret + "1";
}
var s = build_blank(50000) var time0 = Date.now();
lo.trim(s)
var time_cost0 = Date.now() - time0;
console.log("time_cost0: " + time_cost0);
var time1 = Date.now();
lo.toNumber(s) var time_cost1 = Date.now() - time1;
console.log("time_cost1: " + time_cost1);
var time2 = Date.now();
lo.trimEnd(s);
var time_cost2 = Date.now() - time2;
console.log("time_cost2: " + time_cost2);
Command Injection in lodash
lodash versions prior to 4.17.21 are vulnerable to Command Injection via the template function.
Regular Expression Denial of Service in postcss
The package postcss versions before 7.0.36 or between 8.0.0 and 8.2.13 are vulnerable to Regular Expression Denial of Service (ReDoS) via getAnnotationURL() and loadAnnotation() in lib/previous-map.js. The vulnerable regexes are caused mainly by the sub-pattern
\/\*\s* sourceMappingURL=(.*)
var postcss = require("postcss")
function build_attack(n) {
var ret = "a{}"
for (var i = 0; i < n; i++) {
ret += "/*# sourceMappingURL="
}
return ret + "!";
}
postcss.parse('a{}/*# sourceMappingURL=a.css.map */') for (var i = 1; i <= 500000; i++) {
if (i % 1000 == 0) {
var time = Date.now();
var attack_str = build_attack(i) try {
postcss.parse(attack_str) var time_cost = Date.now() - time;
console.log("attack_str.length: " + attack_str.length + ": " + time_cost + " ms");
} catch (e) {
var time_cost = Date.now() - time;
console.log("attack_str.length: " + attack_str.length + ": " + time_cost + " ms");
}
}
}
PostCSS line return parsing error
An issue was discovered in PostCSS before 8.4.31. It affects linters using PostCSS to parse external Cascading Style Sheets (CSS). There may be \r discrepancies, as demonstrated by @font-face{ font:(\r/*);} in a rule.
This vulnerability affects linters using PostCSS to parse external untrusted CSS. An attacker can prepare CSS in such a way that it will contains parts parsed by PostCSS as a CSS comment. After processing by PostCSS, it will be included in the PostCSS output in CSS nodes (rules, properties) despite being originally included in a comment.
