The lodahs package 0.0.1 for Node.js is a Trojan horse, and may have been installed by persons who mistyped the lodash package name. In particular, the Trojan horse finds and exfiltrates cryptocurrency wallets.

An issue was discovered in the BSON ObjectID (aka bson-objectid) package 1.3.0 for Node.js. ObjectID() allows an attacker to generate a malformed objectid by inserting an additional property to the user-input, because bson-objectid will return early if it detects _bsontype==ObjectID in the user-input object. As a result, objects in arbitrary forms can bypass formatting if they have a valid bsontype.

The serialize-to-js NPM package before version 3.0.1 is vulnerable to Cross-site Scripting (XSS). It does not properly mitigate against unsafe characters in serialized regular expressions. This vulnerability is not affected on Node.js environment since Node.js's implementation of RegExp.prototype.toString() backslash-escapes all forward slashes in regular expressions. If serialized data of regular expression objects are used in an environment other than Node.js, it is affected by this vulnerability.

The serialize-javascript npm package before version 2.1.1 is vulnerable to Cross-site Scripting (XSS). It does not properly mitigate against unsafe characters in serialized regular expressions. This vulnerability is not affected on Node.js environment since Node.js's implementation of RegExp.prototype.toString() backslash-escapes all forward slashes in regular expressions. If serialized data of regular expression objects are used in an environment other than Node.js, it is affected by this vulnerability.

The Post editor functionality in the hexo-admin plugin versions 2.3.0 and earlier for Node.js is vulnerable to stored XSS via the content of a post.

There is a stored XSS in Rambox 0.6.9 that can lead to code execution. The XSS is in the name field while adding/editing a service. The problem occurs due to incorrect sanitization of the name field when being processed and stored. This allows a user to craft a payload for Node.js and Electron, such as an exec of OS commands within the onerror attribute of an IMG element.

The csv-parse module before 4.4.6 for Node.js is vulnerable to Regular Expression Denial of Service. The __isInt() function contains a malformed regular expression that processes large crafted input very slowly. This is triggered when using the cast option.

The html-pdf package 2.2.0 for Node.js has an arbitrary file read vulnerability via an HTML file that uses XMLHttpRequest to access a file:/// URL.

eQ-3 Homematic CCU3 AddOn 'Mediola NEO Server for Homematic CCU3' prior to 2.4.5 allows uncontrolled admin access to start or stop the Node.js process, resulting in the ability to obtain mediola configuration details. This is related to improper access control for addons configuration pages and a missing check in rc.d/97NeoServer.

An issue was discovered in the mysql (aka mysqljs) module 2.17.1 for Node.js. The LOAD DATA LOCAL INFILE option is open by default.

It was found that Keycloak's Node.js adapter before version 4.8.3 did not properly verify the web token received from the server in its backchannel logout . An attacker with local access could use this to construct a malicious web token setting an NBF parameter that could prevent user access indefinitely.

Evernote 6.15 on Windows has an incorrectly repaired stored XSS vulnerability. An attacker can use this XSS issue to inject Node.js code under Present mode. After a victim opens an affected note under Present mode, the attacker can read the victim's files and achieve remote execution command on the victim's computer.

Keep-alive HTTP and HTTPS connections can remain open and inactive for up to 2 minutes in Node.js 6.16.0 and earlier. Node.js 8.0.0 introduced a dedicated server.keepAliveTimeout which defaults to 5 seconds. The behavior in Node.js 6.16.0 and earlier is a potential Denial of Service (DoS) attack vector. Node.js 6.17.0 introduces server.keepAliveTimeout and the 5-second default.

In Node.js including 6.x before 6.17.0, 8.x before 8.15.1, 10.x before 10.15.2, and 11.x before 11.10.1, an attacker can cause a Denial of Service (DoS) by establishing an HTTP or HTTPS connection in keep-alive mode and by sending headers very slowly. This keeps the connection and associated resources alive for a long period of time. Potential attacks are mitigated by the use of a load balancer or other proxy layer. This vulnerability is an extension of CVE-2018-12121, addressed in November and impacts all active Node.js release lines including 6.x before 6.17.0, 8.x before 8.15.1, 10.x before 10.15.2, and 11.x before 11.10.1.

utils/find-opencv.js in node-opencv (aka OpenCV bindings for Node.js) prior to 6.1.0 is vulnerable to Command Injection. It does not validate user input allowing attackers to execute arbitrary commands.

The Apache Thrift Node.js static web server in versions 0.9.2 through 0.11.0 have been determined to contain a security vulnerability in which a remote user has the ability to access files outside the set webservers docroot path.

Node.js: All versions prior to Node.js 6.15.0, 8.14.0, 10.14.0 and 11.3.0: Hostname spoofing in URL parser for javascript protocol: If a Node.js application is using url.parse() to determine the URL hostname, that hostname can be spoofed by using a mixed case "javascript:" (e.g. "javAscript:") protocol (other protocols are not affected). If security decisions are made about the URL based on the hostname, they may be incorrect.

Node.js: All versions prior to Node.js 6.15.0, 8.14.0, 10.14.0 and 11.3.0: Slowloris HTTP Denial of Service: An attacker can cause a Denial of Service (DoS) by sending headers very slowly keeping HTTP or HTTPS connections and associated resources alive for a long period of time.

Node.js: All versions prior to Node.js 6.15.0, 8.14.0, 10.14.0 and 11.3.0: Denial of Service with large HTTP headers: By using a combination of many requests with maximum sized headers (almost 80 KB per connection), and carefully timed completion of the headers, it is possible to cause the HTTP server to abort from heap allocation failure. Attack potential is mitigated by the use of a load balancer or other proxy layer.

Node.js: All versions prior to Node.js 6.15.0: Debugger port 5858 listens on any interface by default: When the debugger is enabled with `node --debug` or `node debug`, it listens to port 5858 on all interfaces by default. This may allow remote computers to attach to the debug port and evaluate arbitrary JavaScript. The default interface is now localhost. It has always been possible to start the debugger on a specific interface, such as `node --debug=localhost`. The debugger was removed in Node.js 8 and replaced with the inspector, so no versions from 8 and later are vulnerable.
