This stored cross-site scripting (XSS) vulnerability enables an attacker with admin access to inject malicious scripts into webpages through the plugin's widget configuration options. When users visit a page with an infected widget, the script gets executed in their browser potentially exposing session tokens, cookies and other sensitive data.

How can I tell if my site is vulnerable or has been compromised?

If you have the Enhanced Text Widget installed, you are vulnerable if running any version up to and including 1.6.5. Manually check widget settings for unauthorized code injections. Also scan pages for unwanted iframes, redirects etc. Signs of compromise include unexpected interface/behavior changes, spammy content appearing or users complaining they got hacked after visiting your site.

Question 4

Question 7

Why do plugins have so many vulnerabilities?

Accepted Answer

Why do plugins have so many vulnerabilities?
