- buttons_toolbar: now expect links represented by an array instead of HTML content
- fields_toolbar: now expect a form represented by an array instead of HTML content
- action_plugin: now expect links represented by an array instead of HTML content
Default templates updated accordingly
mprove theme dependent plugin placeholders:
* introduce class LinkFilter to handle link filter operation (and lighten LinkDB).
* handle 'private only' in filtering.
* update template to prefill search fields with current search terms.
* coding style.
* unit test (mostly move from LinkDB to LinkFilter).
PS: preparation for #358#315 and 'AND' search.
Fixes#328 - URL encode links when a redirector is set
* WARNING - template edit - new variable available : "real_url"
Contains the final real url (redirected or any other change on original URL)
* Don't redirect shaares link in RSS/Atom.
* Affects links shaared in description.
* Move text2clickable and keepMultipleSpaces to Utils.php + unit test
UPDATE:
* keepMultipleSpaces renamed to space2nbsp
* space2nbsp improved to handle single space at line beginning
* links in text description aren't 'nofollow' anymore
I reviewed character escaping everywhere with the following ideas:
* use a single common function to escape user data: `escape` using `htmlspecialchars`.
* sanitize fields in `index.php` after reading them from datastore and before sending them to templates.
It means no escaping function in Twig templates.
2 reasons:
* it reduces risks of security issue for future user made templates
* more readable templates
* sanitize user configuration fields after loading them.
Fixes#64
All pages:
- add `urlencode` when passing the version to a custom stylesheet;
- set meaningful values of `alt` and `title` for QR-Code images.
Install page:
- the form's `action` attribute must be non-empty;
- the `valign` attribute is deprecated.

* fix duplicate IDs - #paging_older, #paging_newer become classes as the paging is displayed twice (top, bottom) in the linklist
* fix duplicate IDs - #paging_privatelinks and #paging_linksperpage become classes
* daily links are now valid (use &)
* name attribute is not used anymore on a tag in link list
* center tag is replaced by CSS in picwall and tag cloud
* action in form tag can't be empty, use # instead
* fixed configure table with CSS instead of cellpadding, border, and valign
* export links are now valid
* remove "size" in input tag
* Fix missing alt attributes for img elements
* tpl/daily: Use HTML entities instead of char escape codes
* tpl/export: fix missing </span> closing tag
* Remove obsolete language attribute on <script> elements
Fixesshaarli/Shaarli#29
Style elements refactored as follows:
- use existing ids and classes if possible,
- else, define new ones and stick with the existing naming convention,
- remove hardcoded style attributes from RainTPL templates.
Exception:
In tpl/tagcloud.html, the display size of each tag is computed at page
generation.

jQuery has been removed from all pages, except those who really require
it (like autocomplete in link edition).
Immediate gain: All pages weight 286 kb LESS ! \o/
Highlighting in search results has also been temporarly removed (and
will be re-implemented).
* QR-Code generation now uses a client-side javascript library instead of an external service. This is better for user privacy.
* Library used is http://neocotic.com/qr.js/ (11 kb).
* jQuery is no longer used to display QR-Code (this is a first step in removing jQuery entirely).
* This library is loaded *only* if the QR-Code icon is clicked.
* If javascript is disabled, it will fallback to the external service.
* External service was changed from "invx.com" to "qrfree.kaywa.com" because invx has become bloated.
By loading the javascript library *only* if the icon is clicked, it will prevent the 11 kb lib to be loaded in every page.
Title : Shaarli Vulnerabilities

Vendor : http://sebsauvage.net/wiki/doku.php?id=php:shaarli
Download : https://github.com/sebsauvage/Shaarli/archive/master.zip |
http://sebsauvage.net/files/shaarli_0.0.40beta.zip
Affected versions : master-705F835, 0.0.40-beta (versions below may also
be vulnerable)
Vulnerabilities : Persistent XSS & Unvalidated Redirects and Forwards
Persistent XSS :
- During the instalation or configuration modification, the title field
is vulnerable. e.g <script>alert(1)</script>
Quotes can not be used because of var_export(), but String.fromCharCode
works
- The url field of a link is vulnerable :
When there is no redirector : javascript:alert(1)
Then, the code is triggered when a user click the url of a link
Or with a classic XSS : "><script>alert(1)</script>
Unvalidated Redirects and Forwards :
A request with the param linksperpage or privateonly can be used to
redirect a user to an arbitrary referer
e.g
GET /Audit/Shaarli/master-705f835/?linksperpage=10 HTTP/1.1
Host: 127.0.0.1
Referer: https://duckduckgo.com

Shaarli uses light Javascript in its normal operation, and some jQuery
for some features (autocomplete in tags, QR-Code popup...).
jQuery can be slow on small computers. An option has been added in
configuration screen to disable javascript features which are hard on
CPU.
(Note that the Picture Wall is awfully heavy *without* jQuery.)
(Side note: A *LOT* of users want Shaarli to work without javasript at
all, if possible. That's why I try to use as few javascript as possible:
It keeps Shaarli pages fast.)
