Description
In ElementBrowser.php:
$this->setTitle = $this->curUrlArray['title'] != '-' ? rawurlencode($this->curUrlArray['title']) : '';
...
$JScode = '
...
var add_title="' . ($this->setTitle ? '&curUrl[title]=' . rawurlencode($this->setTitle) : '') . '";
...
';
This is for all curUrl attributes. In the end this means that javascript variables are encoded twice and the prefilled form is also encoded even if it shouldn't be.
I've included patch, but I am not sure if it satisfies all the rules.

This double encoding was introduced in a security fix in 2011.
I believe this fix was wrong, since it should protect against XSS. Double encoding of course does the trick, but it would IMHO be better to simply htmlspecialchar the output.

Yes, that is the fix that broke it. Well the output into the form is already htmlspecialchar'ed:
<td><input type="text" name="ltitle" class="typo3-link-input" onchange="browse_links_setTitle(this.value);" value="' . htmlspecialchars($this->setTitle) . '" /></td>
But there is also the cur_* variables:
var cur_title="' . ($this->setTitle ? $this->setTitle : '') . '";
These are not rendered, they are just sent through
renderPopup_addLink() back to editor, so should they also be htmlspecialchar'ed ?

This needs to be fixed, otherwise it renders editing links impossible when using ElementBrowser (Flux uses it).
