<p class="MsoNormal">I have discovered a remotely exploitable weakness in the ruby-openid library that Rails web applications use to integrate with OpenID Providers. Severity can range from medium to critical, depending on how a web application developer chose
to implement the ruby-openid library. Developers who based their OpenID integration heavily on the "example app" provided by the project are at highest risk.<o:p></o:p></p>

</div>
<div>
<p class="MsoNormal">I hesitate to provide too much detail publicly, as I would prefer to responsibly report the details of this issue privately, to ensure that the OpenID community has time to confirm my findings, implement appropriate code changes, and communicate
effectively with affected developers.<o:p></o:p></p>

</div>
<div>
<p class="MsoNormal">Can one of the main admins on the list please suggest a viable approach? One of the primary maintainers of the ruby-openid project could contact me directly (reply to this email?), or I could be provided with a short list of maintainers
to contact.<o:p></o:p></p>
