Q: How does CVE-2024-3725 affect WordPress websites?

How does CVE-2024-3725 affect WordPress websites? CVE-2024-3725 allows authenticated users with contributor-level access or higher to inject malicious scripts into web pages via the 'titleTag' attribute in the Otter Blocks plugin. This can lead to unauthorized data access, session hijacking, and the potential compromise of visitor information.

Question 1

What is stored cross-site scripting (XSS)?

Accepted Answer

What is stored cross-site scripting (XSS)?

Stored cross-site scripting, or stored XSS, occurs when an attacker can inject a script into a web application’s stored data, which is then sent to users’ browsers. It is dangerous because the malicious script is stored on the server and will affect users who access the infected page, potentially leading to unauthorized access, data theft, and other malicious activities. Stored XSS is particularly insidious as it does not require the attacker to deliver the script with each interaction but is stored and automatically served by the web application itself.
