CVE-2021-29434: Improper validation of URLs ('Cross-site Scripting') in rich text fields
|
|
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
|
|
|
|
This release addresses a cross-site scripting (XSS) vulnerability in rich text fields. When saving the contents of a rich text field in the admin interface, Wagtail did not apply server-side checks to ensure that link URLs use a valid protocol. A malicious user with access to the admin interface could thus craft a POST request to publish content with javascript: URLs containing arbitrary code. The vulnerability is not exploitable by an ordinary site visitor without access to the Wagtail admin.
