The JNDI feature was added into Log4j 2.0-beta9.

Log4j 1.x thus does not have the vulnerable code.

Reason of the issue

It is expected browserslist to return an entry for each version ("safari 15.2", "safari 15.3") instead of a range ("safari 15.2-15.3"). So, this is just a bug in the parsing logic of Safari browser versions which needs to be corrected and will be done soon in fixed versions of Angular 12/Angular 13. Link to details is here.

IMPORTANT UPDATE:

This is fixed in v12.2.16 and v13.2.1, please update if you are experiencing this issue. Users on v11 shouldn't be affected. Link to details is here. If you can not/do not want to update for any reason, then one of the workarounds below can be used.

Workarounds:

Modify .browserslistrc

Add to .browserslistrc such lines:

Keep it easy.
Certs inside your application are complex - they are hard to manage and you will get problems to run your application in a modern cloud environment (start new environments, renew certs, scale your application, ...).

Simple conclusion: Dont implement any certs.

As Mike already pointed out in the comments: WebSockets are just upgraded HTTP(S) connections. A normal webserver (nginx, apache) takes care about the certs. It can be done in kubernetes (as ingress-controller) or with a "bare-metal" webserver.
Both of them should act as a reverse-proxy. This means: Your java-application doesn't know anything about certs. It has just unencrypted connections - like in your code on port 6868.
But the client will not use this port. 6868 is only internally reachable.

The client will call your reverse-proxy at the normal HTTPS port (=443). The reverse-proxy will forward the connection to your java-application.

Here some links for further information:

• nginx reverse-proxy
• nginx reverse-proxy for websocket
• tutorial for java behind reverse-proxy
• LetsEncrypt for automatic and free certs

A "multiarch" Python interpreter built on MacOS is intended to target MacOS-on-Intel and MacOS-on-Apple's-arm64.

There is absolutely no binary compatibility with Linux-on-Apple's-arm64, or with Linux-on-aarch64. You can't run MacOS executables on Linux, no matter if the architecture matches or not.

Huh. This surprised me a bit.

composer is correctly reporting the PHP version it's using. The problem is that it's not using the "correct" PHP interpreter.

The issue arises because of how you are installing composer.

Apparently by doing apk add composer another version of PHP gets installed (you can find it on /usr/bin/php8, this is the one on version 8.0.14).

Instead of letting apk install composer for you, you can do it manually. There is nothing much to install it in any case, no need to go through the package manager. Particularly since PHP has not been installed via the package manager on your base image.

I've just removed the line containing composer from the apk add --update command, and added this somewhere below:

Does a port need to be opened on the clients end to create the channel so the communication line is 2 ways. Perhaps javascript will have some code to open up the clients port.

Issue resolved by reverting back cypress version to 7.6.0.

macOS Monterey introduced AirPlay Receiver running on port 5000. This prevents your web server from serving on port 5000. Receiver already has the port.

You can either:

1. turn off AirPlay Receiver, or;
2. run the server on a different port (normally best).

Turn off AirPlay Receiver

Go to System Preferences → Sharing → Untick Airplay Receiver.

See more details

You should be able to rerun the server now on port 5000 and get a response:

Cypress requires the ability to run its GUI. Depending on your Windows version, you likely need some additional configuration in order to run GUI applications in WSL:

• For all Windows releases, make sure you install the required dependencies:
