Supervisor using my dataset without my consent to submit papers with his other students

I don't see anything problematic here, unless the papers that your advisor wrote with the other students take credit for developing the dataset (which would be a clear ethical violation).

Many papers in computer science use one or several datasets developed by other authors, and it's not a standard practice that the dataset developers are invited to contribute as authors. In fact, doing so may lead to vastly inflated author lists for papers that use many datasets.

Fighting with your supervisor is probably going to negatively affect your own career. Don't let your future hang on this one thing whether it is fair or not. Forcing punishment on the advisor will not get you the letters and recommendations you need to get out and on your own.

Get your own paper published. "Make nice" enough that you get good recommendations. Get away. Build your career.

If you focus just on the "justice" of it you could easily be the one to suffer blowback. Let the past be the past and optimize for your own future. This paper and this dataset isn't going to define your future, nor, hopefully, be the best work of your career.

And, no, I don't make this recommendation happily nor lightly.

It should be considered positively if the dataset is used by completely somebody else. I remember that number of acknowledgments can be used as a metric in some grant application or other types of report.

If you prefer citation or authorship, then I'd recommend to make your dataset citable as soon as possible, e.g. as your own publication, article or as pure dataset. Public dataset can be uploaded and cited by services like Zenodo, which generates citable DOI.

Your career won't be affected by on less co-authorship. More important is your attitude to work. Personally, I'd be very happy if some of my datasets are used by my colleagues, anyway I do not know exactly your circumstances and lab relationships.
