Question 8

Is updating enough to secure my site?

Is updating enough to secure my site?

Updating closes the specific vulnerability but your site may still be compromised. We recommend actively scanning for unwanted code even after updating. Also consider locking down the plugin, limiting contributor permissions and enabling two factor authentication as additional precautions.

Question 9

What if I can't update right now?

Accepted Answer

What if I can't update right now?

Temporarily disabling the plugin can offer some protection if updating is not currently feasible. This would result in loss of functionality however. At minimum, restrict contributor permissions as much as possible. Also change all admin and user passwords in case they were compromised already.

Question 10

Should I switch from Pagelayer after this?

Accepted Answer

Should I switch from Pagelayer after this?

The developers have addressed this vulnerability promptly. However, given the history of stored XSS issues with Pagelayer, switching providers could be prudent until more time has passed. There are several alternative page builders like Elementor to consider if the security issues continue to occur.
