Cross-site scripting (XSS) [a] is a type of security vulnerability that can be found in some web applications. XSS attacks enable attackers to inject client-side scripts into web pages viewed by other users. A cross-site scripting vulnerability may be used by attackers to bypass access controls such as the same-origin policy.
One example goal of a policy is a stricter execution mode for JavaScript in order to prevent certain cross-site scripting attacks. In practice this means that a number of features are disabled by default: Inline JavaScript code [a] <script> blocks, [b] DOM event handlers as HTML attributes (e.g. onclick) The javascript: links; Inline CSS statements
By preventing the malicious application from being able to receive cross-origin responses, the user is no longer in danger of having state changes leaked. [84] This approach is seen in defences such as the deprecated X-Frame-Options header and the newer frame-ancestors directive in Content-Security Policy headers, which allow the victim ...
A time-domain reflectometer; an instrument used to locate the position of faults on lines from the time taken for a reflected wave to return from the discontinuity.. A signal travelling along an electrical transmission line will be partly, or wholly, reflected back in the opposite direction when the travelling signal encounters a discontinuity in the characteristic impedance of the line, or if ...
Attacking web users with Hyper Text Markup Language or Cross-Site Scripting injection. Code injections that target the Internet of Things could also lead to severe consequences such as data breaches and service disruption. [3] Code injections can occur on any type of program running with an interpreter. Doing this is trivial to most, and one of ...
Messages are often delivered right way though very rarely there may be a delay in transit. This is usually due to problems on the mail server, heavy internet traffic, or routing problems. Unfortunately, other than waiting, you won't be able to determine if the message is delayed or undeliverable.

One important solution to XSS vulnerabilities is HTML sanitization. Some browsers include partial protection against reflected XSS attacks, in which the attacker provides a URL including malicious script. However, even users of those browsers are vulnerable to other XSS attacks, such as those where the malicious code is stored in a database.
