Wagtail Vulnerable to Cross-site Scripting in simple_translation admin interface

CVE-2026-28223 / GHSA-p4v8-rw59-93cq

More information

Details

Impact

A stored Cross-site Scripting (XSS) vulnerability exists on confirmation messages within the wagtail.contrib.simple_translation module. A user with access to the Wagtail admin area may create a page with a specially-crafted title which, when another user performs the "Translate" action, causes arbitrary JavaScript code to run. This could lead to performing actions with that user's credentials. The vulnerability is not exploitable by an ordinary site visitor without access to the Wagtail admin.

Patches

Patched versions have been released as Wagtail 6.3.8, 7.0.6, 7.2.3 and 7.3.1.

Workarounds

None

Wagtail Vulnerable to Cross-site Scripting in TableBlock class attributes

CVE-2026-28222 / GHSA-p5cm-246w-84jm

More information

Details

Impact

A stored Cross-site Scripting (XSS) vulnerability exists on rendering TableBlock blocks within a StreamField. A user with access to create or edit pages containing TableBlock StreamField blocks is able to set specially-crafted class attributes on the block which run arbitrary JavaScript code when the page is viewed. When viewed by a user with higher privileges, this could lead to performing actions with that user's credentials. The vulnerability is not exploitable by an ordinary site visitor without access to the Wagtail admin, and only affects sites using TableBlock.

Patches

Patched versions have been released as Wagtail 6.3.8, 7.0.6, 7.2.3 and 7.3.1.

Workarounds

Site owners who are unable to upgrade to the new versions can remediate the vulnerability by setting a template attribute on all TableBlock definitions, referencing a template that does not output class attributes. For example:

<!-- For use with TableBlock(template="path/to/table_block.html") -->
<table>
    {% if table_caption %}
        <caption></caption>
    {% endif %}
    {% if table_header %}
        <thead>
            <tr>
                {% for cell in table_header %}
                    <th scope="col"></th>
                {% endfor %}
            </tr>
        </thead>
    {% endif %}
    <tbody>
        {% for row in data %}
            <tr>
                {% for cell in row %}
                    {% if first_col_is_header and forloop.first %}
                        <th scope="row"></th>
                    {% else %}
                        <td></td>
                    {% endif %}
                {% endfor %}
            </tr>
        {% endfor %}
    </tbody>
</table>
