NodeBB before version 1.14.3 has a bug introduced in version 1.12.2 in the validation logic that makes it possible to change the password of any user on a running NodeBB forum by sending a specially crafted socket.io call to the server. This could lead to a privilege escalation event due via an account takeover. As a workaround you may cherry-pick the following commit from the project's repository to your running instance of NodeBB: 16cee1b03ba3eee177834a1fdac4aa8a12b39d2a. This is fixed in version 1.14.3.

napi_get_value_string_*() allows various kinds of memory corruption in node < 10.21.0, 12.18.0, and < 14.4.0.

Data is truncated wrong when its length is greater than 255 bytes.

node-extend through 0.2.0 is vulnerable to Arbitrary Code Execution. User input provided to the argument `A` of `extend` function`(A,B,as,isAargs)` located within `lib/extend.js` is executed by the `eval` function, resulting in code execution.

TLS session reuse can lead to host certificate verification bypass in node version < 12.18.0 and < 14.4.0.

In nghttp2 before version 1.41.0, the overly large HTTP/2 SETTINGS frame payload causes denial of service. The proof of concept attack involves a malicious client constructing a SETTINGS frame with a length of 14,400 bytes (2400 individual settings entries) over and over again. The attack causes the CPU to spike at 100%. nghttp2 v1.41.0 fixes this vulnerability. There is a workaround to this vulnerability. Implement nghttp2_on_frame_recv_callback callback, and if received frame is SETTINGS frame and the number of settings entries are large (e.g., > 32), then drop the connection.

node-dns-sync (npm module dns-sync) through 0.2.0 allows execution of arbitrary commands . This issue may lead to remote code execution if a client of the library calls the vulnerable method with untrusted input. This has been fixed in 0.2.1.

node-rules including 3.0.0 and prior to 5.0.0 allows injection of arbitrary commands. The argument rules of function "fromJSON()" can be controlled by users without any sanitization.

node-mpv through 1.4.3 is vulnerable to Command Injection. It allows execution of arbitrary commands via the options argument.

node-key-sender through 1.0.11 is vulnerable to Command Injection. It allows execution of arbitrary commands via the 'arrParams' argument in the 'execute()' function.
