What happened?
TODO example project is vulnerable to XSS/HTML injection attacks.
Payload Used:
<button onclick='javascript:confirm("vulnerable");document.location.href="https://dmdhrumilmistry.github.io"'>click me</button>
Result:
Issue: Since most of the devs will be learning pyscript referring the examples, they'll be making applications which will be vulnerable to XSS/HTML injection. We would appreciate if pyscript team can also use secure coding techniques while creating examples; this will help devs to build secure applications.
What browsers are you seeing the problem on? (if applicable)
No response
Console info
No response
Additional Context
creating a cheatsheet might help devs to avoid such common issues in their applications
@dmdhrumilmistry I'm afraid I am not sure I am following ... that's just how any Web page works?
<!doctype html>
<button onclick='javascript:confirm("vulnerable");document.location.href="https://dmdhrumilmistry.github.io"'>click me</button>
you are not using a py-click
handler, you are showing any valid HTML, so what has this project in particular to do with your example? 🤔
@dmdhrumilmistry wait a minute ... are you saying that if you add HTML as TODO item content that gets injected as HTML? Not sure that's just intentional / by-design for demo sake, but if that's the case we might avoid tasks as HTML, yes 👍
@dmdhrumilmistry I've just tested locally and also checked the file part where we use innerText, not innerHTML
to add the task ... this is what I see so we might need a step-by-step way to reproduce your issue or maybe it was fixed already (a month ago) and it's not live yet.
/cc @antocuni @fpliger
edit This is odd ... last change is from a year ago or something around that code https://github.com/pyscript/pyscript/commit/707474e835a315f4e94ac1dae3ebebc563f4988a
using innerText
would fix the issue! ohh okay. cool. When will it be deployed?
@dmdhrumilmistry I am not sure when it's planned, but maybe @antocuni or @FabioRosado or @fpliger would know. They are at PyCon right so there might be some unintentional delay in answering this, the good thing is that current project doesn't break our expectations so please be patient, thank you!
I may be wrong since I've been focused on the pyscript.com side of things but I'm assuming that the next release will happen when the work for workers is a bit more stable 🤔
okay cool!
Sorry I missed the thread.
Yes, next release should be happening within a month timeframe (the big task holding the release is indeed workers, as @FabioRosado mentioned).
@WebReflection @dmdhrumilmistry am I reading correctly that, given the comments above around innerText
, we can close this issue?
@fpliger the label waiting for release
is there to signal this is not a bug (anymore) and will be closed once we release. If we close it before that there's no signal the bug is gone because there's no opened issue so we should just ignore these labelled issues and close them once we release.
Sorry I missed the thread.

@fpliger, I'll prefer to close this once after releasing the fix. Else team might miss the issue.
@dmdhrumilmistry 👍
@WebReflection Ok. This is different than the process we were adopting earlier (I probably missed the changes). I guess the rationale here is reflecting the state of the latest released version vs the state of main
. We are due to sit down and put down a project/contribution workflow and guidelines anyway, so let's make sure we talk through this when we have that conversation
@fpliger in all fairness it was my initiative and I've asked in the channel if that was OK but I guess I wasn't too loud there.
The (personal) idea was to meet users expectations, see:
I'll prefer to close this once after releasing the fix. Else team might miss the issue.
to which I agree specially because we don't have a fast release cycle so that it's easier to see an open bug exist (avoiding duplicates before we release) and the label makes it easy to filter by label and close whatever released, once released.
Happy to discuss this or formalize it once we have a workflow page to look at +1
sorry for popping in randomly with an "unrelated" statement.
"YOU GUYS/GALS/UNDISCLOSED ROCK"
ps: and keep on keepin' on
@Po-code TY so much for the kind words!! So much appreciated!! ❤️
Well met friend! But It is i that thanks you. Im not much of a contributer to the open source (publicly anyways) as a result..my github profile hasnt earned badges and the repo isnt populated with any software/libraries/packages that I have built or hacked together lol.. Anyways if you want to know more about some of things I built or feel like maybe even incorporating some of them into some of your or your teams projects. Dont hesitate to let me know and ill gladly send you the works with hopes of feedback or some advice/pointers.

I believe this got released by this time :sweat_smile:

Hello again. Cant believe half a year has gone by since my previous comment.
apologies we've been busy "changing the world" but it's still our duty to go through the backlog and close "the closable", I hope you can forgive us for the wait.
Anyways my statement still stands
There is no XSS attack vector in current release and nothing in here is a vector for XSS so your statement should be reconsidered? If you can provide any XSS that shows something undesired and that's not already part of the HTML / W3C standard, we'd be happy to fix it ASAP too.
So far, that example was not presented or not valid with our current offer.

im sorry let me clear this up for you, I never was apart of the XSS subject of this conversation I only left a comment that was unrelated to the topic, that is what I meant when I said "statement", as in, from my previous comment 6 months ago. I posted this as a renewal of my compliment for/to/of the py-script team/collab devs. And Why? because I got an email notification that that linked me to here. Hope this helps.
