Publ 0.5.8, Authl 0.3.1, and IndieAuth security

Posted Wednesday, October 30 at 7:11 PM (3 weeks ago)

So, both Publ and Authl had a pretty na├»ve issue with the identity verification step of the IndieAuth flow; it simply accepted whatever the authorization endpoint said the user’s identity was. This made it very simple to spoof one’s identity and log in as anyone on any Publ or Authl site.

Authl 0.3.1 fixes the problem with the IndieAuth login flow, and Publ 0.5.8 fixes the problem with the Bearer token flow.

The shape of the float (v0.3.1)

Did you know that CSS3 has a style called shape-outline? It’s pretty neat, it makes it so that a floated object gets a shape based on the alpha channel of its specified image. But it’s kind of a pain to set up; in plain HTML it looks something like this:

<img src="/path/to/image.png" width="320" height="320"
    style="shape-outline:url('/path/to/image.png');float: left">

and if you want a different shape mask for your image than its own alpha channel, you have to do a bunch of stuff like making sure that the image sizes are the same and whatever.
