<p>Hi all,</p>
<p>unfortunately I can't attend the call today. <br>
</p>
<p>Nonetheless, I'd like to draw your attention to two topics on the
OAuth mailing list:</p>
<p>Firstly, a new draft for the "iss" parameter, which we're also
using in FAPI.<br>
<a class="moz-txt-link-freetext" href="https://mailarchive.ietf.org/arch/msg/oauth/U5PHuXAl4fTiQ0df2cLFtpURAvI/">https://mailarchive.ietf.org/arch/msg/oauth/U5PHuXAl4fTiQ0df2cLFtpURAvI/</a></p>
<p>And a security problem when *not* using iss but relying on
per-issuer redirect URIs:<br>
<a class="moz-txt-link-freetext" href="https://mailarchive.ietf.org/arch/msg/oauth/RjbSwFRmLsk0EgAY2Ter-nw66EY/">https://mailarchive.ietf.org/arch/msg/oauth/RjbSwFRmLsk0EgAY2Ter-nw66EY/</a></p>
<p>Note that JARM provides the same protection as the "iss"
parameter. FAPI 1 Pt. 2 should therefore be fine. <br>
</p>
<p>My plan is to update the FAPI 2 drafts to remove the per-issuer
redirect URIs and to enforce checking the "iss" in the response.</p>
