Self-XSS (self cross-site scripting) is a type of security vulnerability used to gain control of victims' web accounts. In a Self-XSS attack, the victim of the attack runs malicious code in their own web browser, thus exposing personal information to the attacker.
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.
Graph showing the progress of the XSS worm that impacted 2525 users on Justin.tv. Justin.tv was a video casting website with an active user base of approximately 20 thousand users. The cross-site scripting vulnerability that was exploited was that the "Location" profile field was not properly sanitized before its inclusion in a profile page.
In computer security, a reflection attack is a method of attacking a challenge–response authentication system that uses the same protocol in both directions. That is, the same challenge–response protocol is used by each side to authenticate the other side.
Cross-site scripting (XSS) enables attackers to inject and run JavaScript-based malware when input checking is insufficient to reject the injected code. [28] XSS can be persistent, when attackers save the malware in a data field and run it when the data is loaded; it can also be loaded using a malicious URL link (reflected XSS). [28]

The attack is blind: the attacker cannot see what the target website sends back to the victim in response to the forged requests, unless they exploit a cross-site scripting or other bug at the target website. Similarly, the attacker can only target any links or submit any forms that come up after the initial forged request if those subsequent ...
While JSONP can cause cross-site scripting (XSS) issues when the external site is compromised, CORS allows websites to manually parse responses to increase security. [1] The main advantage of JSONP was its ability to work on legacy browsers which predate CORS support (Opera Mini and Internet Explorer 9 and earlier). CORS is now supported by ...
