GitHub Vulnerability Alerts

CVE-2021-43138

A vulnerability exists in Async through 3.2.1 for 3.x and through 2.6.3 for 2.x (fixed in 3.2.2 and 2.6.4), which could let a malicious user obtain privileges via the mapValues() method.

CVE-2017-16137

Affected versions of debug are vulnerable to regular expression denial of service when untrusted user input is passed into the o formatter.

As it takes 50,000 characters to block the event loop for 2 seconds, this issue is a low severity issue.

Recommendation

Version 2.x.x: Update to version 2.6.9 or later.
Version 3.x.x: Update to version 3.1.0 or later.

CVE-2022-33987

The got package before 12.1.0 for Node.js allows a redirect to a UNIX socket.

CVE-2020-26237

Impact

Affected versions of this package are vulnerable to Prototype Pollution. A malicious HTML code block can be crafted that will result in prototype pollution of the base object's prototype during highlighting. If you allow users to insert custom HTML code blocks into your page/app via parsing Markdown code blocks (or similar) and do not filter the language names the user can provide you may be vulnerable.

The pollution should just be harmless data but this can cause problems for applications not expecting these properties to exist and can result in strange behavior or application crashes, i.e. a potential DOS vector.

If your website or application does not render user provided data it should be unaffected.

Patches

Versions 9.18.2 and 10.1.2 and newer include fixes for this vulnerability. If you are using version 7 or 8 you are encouraged to upgrade to a newer release.

Workarounds

Patch your library

Manually patch your library to create null objects for both languages and aliases:

const HLJS = function(hljs) {
  // ...
  var languages = Object.create(null);
  var aliases = Object.create(null);

Filter out bad data from end users

Filter the language names that users are allowed to inject into your HTML to guarantee they are valid.

Impact: Potential ReDOS vulnerabilities (exponential and polynomial RegEx backtracking)

oswasp:

The Regular expression Denial of Service (ReDoS) is a Denial of Service attack, that exploits the fact that most Regular Expression implementations may reach extreme situations that cause them to work very slowly (exponentially related to input size). An attacker can then cause a program using a Regular Expression to enter these extreme situations and then hang for a very long time.

If are you are using Highlight.js to highlight user-provided data you are possibly vulnerable. On the client-side (in a browser or Electron environment) risks could include lengthy freezes or crashes... On the server-side infinite freezes could occur... effectively preventing users from accessing your app or service (ie, Denial of Service).

This is an issue with grammars shipped with the parser (and potentially 3rd party grammars also), not the parser itself. If you are using Highlight.js with any of the following grammars you are vulnerable. If you are using highlightAuto to detect the language (and have any of these grammars registered) you are vulnerable. Exponential grammars (C, Perl, JavaScript) are auto-registered when using the common grammar subset/library require('highlight.js/lib/common') as of 10.4.0 - see https://cdn.jsdelivr.net/gh/highlightjs/cdn-release@10.4.0/build/highlight.js

All versions prior to 10.4.1 are vulnerable, including version 9.18.5.

Grammars with exponential backtracking issues:

  • c-like (c, cpp, arduino)
  • handlebars (htmlbars)
  • gams
  • perl
  • jboss-cli
  • r
  • erlang-repl
  • powershell
  • routeros
  • livescript (10.4.0 and 9.18.5 included this fix)
  • javascript & typescript (10.4.0 included partial fixes)

And of course any aliases of those languages have the same issue. ie: hpp is no safer than cpp.

Grammars with polynomial backtracking issues:

  • kotlin
  • gcode
  • d
  • aspectj
  • moonscript
  • coffeescript/livescript
  • csharp
  • scilab
  • crystal
  • elixir
  • basic
  • ebnf
  • ruby
  • fortran/irpf90
  • livecodeserver
  • yaml
  • x86asm
  • dsconfig
  • markdown
  • ruleslanguage
  • xquery
  • sqf

And again: any aliases of those languages have the same issue. ie: ruby and rb share the same ruby issues.

Patches

  • Version 10.4.1 resolves these vulnerabilities. Please upgrade.

Workarounds / Mitigations

  • Discontinue use the affected grammars. (or perhaps use only those with poly vs exponential issues)
  • Attempt cherry-picking the grammar fixes into older versions...
  • Attempt using newer CDN versions of any affected languages. (ie using an older CDN version of the library with newer CDN grammars). Your mileage may vary.

CVE-2020-8175

Uncontrolled resource consumption in jpeg-js before 0.4.0 may allow attacker to launch denial of service attacks using specially a crafted JPEG image.

CVE-2022-25851

The package jpeg-js before 0.4.4 is vulnerable to Denial of Service (DoS) where a particular piece of input will cause the program to enter an infinite loop and never return.

CVE-2018-3721

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.

Recommendation

Update to version 4.17.5 or later.

CVE-2018-16487

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 {constructor: {prototype: {...}}} causing the addition or modification of an existing property that will exist on all objects.

Recommendation

Update to version 4.17.11 or later.

CVE-2019-10744

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.

Recommendation

Update to version 4.17.12 or later.

CVE-2019-1010266

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.

CVE-2020-28500

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)

CVE-2021-23337

lodash versions prior to 4.17.21 are vulnerable to Command Injection via the template function.

CVE-2020-8203

Versions of lodash prior to 4.17.19 are vulnerable to Prototype Pollution. The function zipObjectDeep allows a malicious user to modify the prototype of Object if the property identifiers are user-supplied. Being affected by this issue requires zipping objects based on user-provided property 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.

CVE-2020-7598

Affected versions of minimist are vulnerable to prototype pollution. Arguments are not properly sanitized, allowing an attacker to modify the prototype of Object, causing the addition or modification of an existing property that will exist on all objects.
Parsing the argument --__proto__.y=Polluted adds a y property with value Polluted to all objects. The argument --__proto__=Polluted raises and uncaught error and crashes the application.
This is exploitable if attackers have control over the arguments being passed to minimist.

Recommendation

Upgrade to versions 0.2.1, 1.2.3 or later.

CVE-2021-44906

Minimist <=1.2.5 is vulnerable to Prototype Pollution via file index.js, function setKey() (lines 69-95).

CVE-2021-3803

nth-check is vulnerable to Inefficient Regular Expression Complexity
