## FAQ

### What does this mean?

The plugin's Codestar-derived backup AJAX handlers (csf-export, csf-import, csf-reset) do not check authorization properly. A user without the right permission can read, overwrite or delete WordPress options, including wp_user_roles, which can be used to gain administrator privileges.

### Am I affected, and how do I check?

Versions 2.3.23 up to, but not including, 2.3.26 of Product Gallery Slider & Additional Variation Images for WooCommerce by Codeixer are in the affected range. The settings page is limited to users with the manage_woocommerce capability, and the handlers are present in the plugin code; check the installed version in the plugin list or the Plugins screen in WordPress admin.

### What should I do about it?

Upgrade the plugin to version 2.3.26 or later, which is the fixed release.

### Is it being exploited?

It is not in CISA's Known Exploited Vulnerabilities catalog, and CISA's SSVC assessment does not mark exploitation as active. That does not mean it has not been attacked: vendors and researchers can report attacks before CISA lists them. No public exploit code is tracked.
