The power of our XSS cheat sheet is we get fantastic contributions from the web security community and this update is no exception. We had valuable contributions from Mozilla to remove events that no longer work with the marquee tag on Firefox.

There was a wonderfully obscure Safari only vector that used the event onwebkitplaybacktargetavailabilitychanged from @amirmsafari that works on audio and video tags:

We had a submission from @Wcraft-log with the onpointercancel event that requires heavy user interaction:

@Filipnyquist pointed out that we didn't document that pretty much every element can now use the autofocus attribute. This was discovered earlier by @RenwaX23 and @lbherrera_ .

Finally we had a submission from @zhenwarx that showed there are a bunch of webkit events we missed that require user interaction with the trackpad.

Big thanks to the web security community for keeping the XSS cheat sheet up to date with the latest XSS vectors. If you would like to contribute please raise an issue or a PR .

Note: If you are wondering what we use to generate code snippet images. We use the excellent online tool Ray.so .
