Question 1

How do I know if my site is affected by this vulnerability?

Accepted Answer

How do I know if my site is affected by this vulnerability?

You should check if you have Password Protected activated on your WordPress site. Then look at what version is currently running - any release before 2.6.7 is vulnerable to the stored XSS issue allowing malicious scripts to be injected. So you'd want to verify the plugin is updated if a compromised version is still active.

Question 2

What exactly is the security risk being reported?

Accepted Answer

What exactly is the security risk being reported?

The risk is that attackers who gain admin access, either via compromised credentials or another vulnerability, can store arbitrary web scripts in Password Protected's Google Captcha site key setting. These scripts would then execute any time a normal user visits a page that Password Protected is protecting access to. This would enable potential session hijacking, malware distribution, or phishing.

Question 3

Is updating the only thing needed to protect my site?

Accepted Answer

Is updating the only thing needed to protect my site?

Updating to Password Protected version 2.6.7 prevents the vulnerability from being leveraged in the future. However, if your site was already compromised any stored scripts would remain. You should check previous protected pages for unauthorized code even after updating. Removing plugins may also be wise if your site was definitely compromised.

Question 4

How urgent is this update? My site is working fine as-is.

Accepted Answer

How urgent is this update? My site is working fine as-is.

Leaving your site open to stored XSS attacks should be considered a high priority to address. Even if things seem fine currently, threats like data theft or phishing often go undetected at first. And the damage done builds up over time. We recommend updating within 7 days if possible.

Question 5

What happens if I deactivate rather than update the plugin?

Accepted Answer

What happens if I deactivate rather than update the plugin?

Deactivating rather than updating Password Protected may remove the vulnerability but also breaks any content restrictions in place. You'd need to replace its functionality with another access control plugin. Updating is simpler and retains your existing protected pages seamlessly while closing the XSS vulnerability at the same time.

Question 6

Could outdated WordPress core or other plugins make me vulnerable?

Accepted Answer

Could outdated WordPress core or other plugins make me vulnerable?

Outdated plugins and WordPress core often contain security issues as well. We recommend a "defense in depth" strategy, keeping everything across your stack updated. However, currently this stored XSS vulnerability only exists in Password Protected versions prior to 2.6.7 even if other software is outdated.

Question 7

Is there any way to detect is someone has added malicious scripts already?

Accepted Answer

Is there any way to detect is someone has added malicious scripts already?

Reviewing your Google Captcha Site Keys for unexpected or unauthorized code is one way to check for existing scripts that may signal compromise. You can also manually examine pages protected by the plugin for anything suspicious. But some attacks like session hijacking are harder to detect through visual inspection alone.

Question 8

How can I safely update the plugin? I'm worried about breaking my site.

Accepted Answer

How can I safely update the plugin? I'm worried about breaking my site.

We recommend creating a full WordPress backup, testing the updated plugin on a staging copy of your site, and installing carefully monitored. The latest version of any trusted plugin is unlikely to cause issues but extensive testing is wise. Our guide to updating securely helps walk through best practices.

Question 10

Who discovered this vulnerability originally? Should I trust their intentions?

Accepted Answer

Who discovered this vulnerability originally? Should I trust their intentions?

The security researcher, Felipe Restrepo Rodriguez, responsibly disclosed the vulnerability to the Password Protected developers through proper channels. The rapid patching indicates good faith on all sides aiming for a secure ecosystem - not exploiting sites for illegal gain. Ethical disclosure efforts should be supported.
