- If you cannot update right away, deactivate it until you can.
- Turn on auto-updates for it: Plugins → “Enable auto-updates” on its row.
- Not sure which version you run? Check your version against every known SiteOrigin Widgets Bundle issue.

wp plugin get so-widgets-bundle --field=version. - If you ran an affected version and something looks off (new admin users, spam pages, redirects), run the free scan below.
The advisory
The SiteOrigin Widgets Bundle plugin for WordPress is vulnerable to Directory Traversal in all versions up to, and including, 1.74.3 via the get_instance_css function. This makes it possible for authenticated attackers, with contributor-level access and above, to read the contents of arbitrary files on the server, which can contain sensitive information. The widget's normal update()/sanitize_field_input() pipeline — which would reject non-hex color values — is bypassed entirely because the [siteorigin_widget] shortcode handler calls $the_widget->widget() directly on the attacker-supplied decoded JSON instance.
