Question 9

What is stored cross-site scripting (XSS)?

Accepted Answer

What is stored cross-site scripting (XSS)?

Stored cross-site scripting (XSS) is a type of security exploit where attackers inject malicious scripts into a web application, which then stores these scripts. When other users access the compromised pages, the stored scripts execute, potentially stealing data, hijacking user sessions, or performing other malicious actions.

Stored XSS is particularly dangerous because the malicious scripts are saved by the server and can affect multiple users over time without the need for direct interaction with the attacker's malicious payload.

Why is regular plugin maintenance important for WordPress site security?

Accepted Answer

Why is regular plugin maintenance important for WordPress site security?

Regular plugin maintenance is crucial for WordPress site security because vulnerabilities, like those found in EmbedPress, can emerge at any time. Keeping plugins updated ensures that any known security issues are patched, protecting your site from potential exploits.

Regular maintenance also helps in optimizing site performance and compatibility, ensuring that your site remains secure, efficient, and reliable for your users, which is especially important for small business owners who rely on their online presence.
