CVE-2020-11037 WRITEUP MEDIUM WRITEUP
Wagtail <2.7.3-2.8.2 - Info Disclosure
In Wagtail before versions 2.7.3 and 2.8.2, a potential timing attack exists on pages or documents that have been protected with a shared password through Wagtail's "Privacy" controls. This password check is performed through a character-by-character string comparison, and so an attacker who is able to measure the time taken by this check to a high degree of accuracy could potentially use timing differences to gain knowledge of the password. This is [understood to be feasible on a local network, but not on the public internet](https://groups.google.com/d/msg/django-developers/iAaq0pvHXuA/fpUuwjK3i2wJ). Privacy settings that restrict access to pages/documents on a per-user or per-group basis (as opposed to a shared password) are unaffected by this vulnerability. This has been patched in 2.7.3, 2.8.2, 2.9.

CVE-2020-11001 WRITEUP MEDIUM WRITEUP
Wagtail 1.9-2.7.1 - Stored Cross-Site Scripting in Page Revision Comparison View
In Wagtail before versions 2.8.1 and 2.7.2, a cross-site scripting (XSS) vulnerability exists on the page revision comparison view within the Wagtail admin interface. A user with a limited-permission editor account for the Wagtail admin could potentially craft a page revision history that, when viewed by a user with higher privileges, could perform actions with that user's credentials. The vulnerability is not exploitable by an ordinary site visitor without access to the Wagtail admin. Patched versions have been released as Wagtail 2.7.2 (for the LTS 2.7 branch) and Wagtail 2.8.1 (for the current 2.8 branch).

CVE-2020-15118 WRITEUP MEDIUM WRITEUP
Wagtail <2.7.4, 2.9.3 - Info Disclosure
In Wagtail before versions 2.7.4 and 2.9.3, when a form page type is made available to Wagtail editors through the `wagtail.contrib.forms` app, and the page template is built using Django's standard form rendering helpers such as form.as_p, any HTML tags used within a form field's help text will be rendered unescaped in the page. Allowing HTML within help text is an intentional design decision by Django; however, as a matter of policy Wagtail does not allow editors to insert arbitrary HTML by default, as this could potentially be used to carry out cross-site scripting attacks, including privilege escalation. This functionality should therefore not have been made available to editor-level users. The vulnerability is not exploitable by an ordinary site visitor without access to the Wagtail admin. Patched versions have been released as Wagtail 2.7.4 (for the LTS 2.7 branch) and Wagtail 2.9.3 (for the current 2.9 branch). In these versions, help text will be escaped to prevent the inclusion of HTML tags. Site owners who wish to re-enable the use of HTML within help text (and are willing to accept the risk of this being exploited by editors) may set WAGTAILFORMS_HELP_TEXT_ALLOW_HTML = True in their configuration settings. Site owners who are unable to upgrade to the new versions can secure their form page templates by rendering forms field-by-field as per Django's documentation, but omitting the |safe filter when outputting the help text.

CVE-2023-28837 WRITEUP MEDIUM WRITEUP
Wagtail < 4.1.4 and 4.2-4.2.2 - Authenticated Denial of Service via Large File Upload
Wagtail is an open source content management system built on Django. Prior to versions 4.1.4 and 4.2.2, a memory exhaustion bug exists in Wagtail's handling of uploaded images and documents. For both images and documents, files are loaded into memory during upload for additional processing. A user with access to upload images or documents through the Wagtail admin interface could upload a file so large that it results in a crash of denial of service. The vulnerability is not exploitable by an ordinary site visitor without access to the Wagtail admin. It can only be exploited by admin users with permission to upload images or documents. Image uploads are restricted to 10MB by default, however this validation only happens on the frontend and on the backend after the vulnerable code. Patched versions have been released as Wagtail 4.1.4 and Wagtail 4.2.2). Site owners who are unable to upgrade to the new versions are encouraged to add extra protections outside of Wagtail to limit the size of uploaded files.
CVSS 4.9
CVE-2023-45809 WRITEUP LOW WRITEUP
Wagtail < 4.1.9 - Authenticated Information Disclosure via User Account Bulk Action URL
Wagtail is an open source content management system built on Django. A user with a limited-permission editor account for the Wagtail admin can make a direct URL request to the admin view that handles bulk actions on user accounts. While authentication rules prevent the user from making any changes, the error message discloses the display names of user accounts, and by modifying URL parameters, the user can retrieve the display name for any user. The vulnerability is not exploitable by an ordinary site visitor without access to the Wagtail admin. Patched versions have been released as Wagtail 4.1.8 (LTS), 5.0.5 and 5.1.3. The fix is also included in Release Candidate 1 of the forthcoming Wagtail 5.2 release. Users are advised to upgrade. There are no known workarounds for this vulnerability.
CVSS 2.7
CVE-2024-32882 WRITEUP LOW WRITEUP
Wagtail 6.0.0-6.0.3 - Permission Bypass via FieldPanel Permission Argument
Wagtail is an open source content management system built on Django. In affected versions if a model has been made available for editing through the `wagtail.contrib.settings` module or `ModelViewSet`, and the `permission` argument on `FieldPanel` has been used to further restrict access to one or more fields of the model, a user with edit permission over the model but not the specific field can craft an HTTP POST request that bypasses the permission check on the individual field, allowing them to update its value. This vulnerability is not exploitable by an ordinary site visitor without access to the Wagtail admin, or by a user who has not been granted edit access to the model in question. The editing interfaces for pages and snippets are also unaffected. Patched versions have been released as Wagtail 6.0.3 and 6.1. Wagtail releases prior to 6.0 are unaffected. Users are advised to upgrade. Site owners who are unable to upgrade to a patched version can avoid the vulnerability as follows: 1.For models registered through `ModelViewSet`, register the model as a snippet instead; 2. For settings models, place the restricted fields in a separate settings model, and configure permission at the model level.

CVE-2024-35228 WRITEUP MEDIUM WRITEUP
Wagtail 6.0.0-6.0.4 and 6.1.0-6.1.1 - Authenticated Improper Permission Handling in Settings Module
Wagtail is an open source content management system built on Django. Due to an improperly applied permission check in the `wagtail.contrib.settings` module, a user with access to the Wagtail admin and knowledge of the URL of the edit view for a settings model can access and update that setting, even when they have not been granted permission over the model. The vulnerability is not exploitable by an ordinary site visitor without access to the Wagtail admin. Patched versions have been released as Wagtail 6.0.5 and 6.1.2. Wagtail releases prior to 6.0 are unaffected. Users are advised to upgrade. Site owners who are unable to upgrade to a patched version can avoid the vulnerability in `ModelViewSet` by registering the model as a snippet instead. No workaround is available for `wagtail.contrib.settings`.
