|
### Security: Cross-site scripting (XSS) on text transformations in templates
|
|
|
|
The default casting for `Text` and `Varchar` database field classes usually auto-escapes
|
|
field values when they are inserted into a template. For some text transformations
|
|
on those fields, this wasn't correctly applied. The following methods are affected:
|
|
|
|
* `AbsoluteLinks()`,
|
|
* `BigSummary()`,
|
|
* `ContextSummary()`,
|
|
* `EscapeXML()`,
|
|
* `FirstParagraph()`,
|
|
* `FirstSentence()`,
|
|
* `Initial()`,
|
|
* `LimitCharacters()`,
|
|
* `LimitSentences()`,
|
|
* `LimitWordCount()`,
|
|
* `LimitWordCountXML()`,
|
|
* `Lower()`
|
|
* `LowerCase()`
|
|
* `NoHTML()`,
|
|
* `Summary()`,
|
|
* `Upper()`
|
|
* `UpperCase()`
|
|
* `URL()`
|
|
|
|
If you have used any of these transformations with untrusted values
|
|
(e.g. from a user-submitted form), please consider updating.
|
|
More info about SilverStripe's casting logic is available in the "[security](/developer_guides/security)" documentation.
|
|
|
|
### Security: Cross-site scripting (XSS) related to page titles in the CMS
|
|
|
|
The page title data wasn't escaped correctly in the `SilverStripeNavigator`
|
|
as well as the updated page title in the CMS tree after saving.
