About This File


XenForo 2.2.1 is now available for all licensed customers to download. We strongly recommend that all customers running previous versions of XenForo 2.2 upgrade to this release to benefit from increased stability.

Most importantly, this release fixes two potential security vulnerabilities in XenForo.

The issues are XSS vulnerabilities. XSS (Cross Site Scripting) issues allow scripts and malicious HTML to be injected into the page, potentially allowing data theft or unauthenticated access.

XenForo extends thanks to security researcher Vincent ibn Winnie for reporting the issues.

We recommend doing a full upgrade to resolve the issues, but a patch can be applied manually. See below for further details.

Applying a patch manually
Download the 221patch.zip file attached to this message. It will contain the following file:
Extract the zip file to your computer and upload the contents to the root of your XenForo installation. This should overwrite the files on your server with the new version.

Note: If you decide to patch the files instead of doing a full upgrade, your "File health check" will report these three files as having "Unexpected contents". Because these files no longer contain the same contents your version of XF was shipped with, this is expected and can be safely ignored.

Some of the other changes in XF 2.2.1 include:
Fix erroneous phrase in success alert when posting a reply before registering
Ensure that service worker offline caching does not trigger session activity updates (or various other assertions)
Allow insertTable and xfBbCode commands to be added to custom dropdowns. Prevent paragraphFormat command being added.
Empty the mail queue when upgrading to 2.2 due to underlying Swiftmailer changes and catch errors (as well as exceptions) during mail sending to prevent queue items from becoming stuck.
Only bail out of toggling the editor preview when the editor is empty if you are not already previewing.
Fix displaying emoji phrases when the shortname contains an accented character and fix issue with accented shortname emojis from being converted.
Bail out of matching a URL to BB code media sites if the string matches censor words.
More consistently apply permission dependencies when passing from global to content-level permissions. Display permission changes due to failed dependencies when analyzing.
Expose unread state for conversations and conversation messages
Bypass global visibility check when trying to validate usernames for registration
Add missing phrases when Gravatar rebuild is run.
On the registration form, update the username field's explain text as usernames can be changed now
Ensure article preview images aren't underlined when hovered over
In the RTE, do not parse for emojis when smilies are disabled. This is consistent with how BB code is normally rendered.
Ensure that Attachment::getDirectUrl only returns raw display URLs when the attachment is viewable
Remove content voting links from HTML if the visitor cannot use them
Apply width: auto to the small logo to ensure it maintains the correct aspect ratio when resized
Fix email sharing link
Add PHPDocs to noPermission() and notFound() controller methods

The following public templates have had changes:


XenForo 2.2.1 вече е достъпен за изтегляне от всички лицензирани клиенти. Силно препоръчваме на всички клиенти, работещи с предишни версии на XenForo 2.2, да обновят до 2.2.1, за да се възползвате от по добра стабилност.

Най-важното е, че тази версия поправя две потенциални уязвимости в сигурността в XenForo.

Като  XSS уязвимостта.
Проблемите с XSS (Cross Site Scripting) позволяват в страницата да се инжектират скриптове и злонамерен HTML код, което потенциално позволява кражба на данни или неоторизиран достъп.

Препоръчваме да направите пълно обновяване за да разрешите проблемите, но ъпдейта може да се приложи ръчно. Вижте по-долу за повече подробности.

Прилагане на ъбдейта ръчно
Изтеглете файла 221patch.zip, прикачен към това съобщение. Той ще съдържа следния файл:
src / XF / BbCode / Renderer / Html.php
Изтеглете zip файла на вашия компютър и качете съдържанието в съответната ваша директория на  XenForo. Това трябва да замени файловете настарата версия с новата.
