In addition, DOMPurify parses the id and name attributes of injected elements to identify if they can collide with existing global functions. [21] However, recent vulnerabilities related to DOM clobbering have been found in DOMPurify and similar libraries such as HTML Janitor, which indicate that these libraries only protect against specific ...
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.
In data sanitization, HTML sanitization is the process of examining an HTML document and producing a new HTML document that preserves only whatever tags and attributes are designated "safe" and desired.
Cache-timing attacks rely on the ability to infer hits and misses in shared caches on the web platform. [54] One of the first instances of a cache-timing attack involved the making of a cross-origin request to a page and then probing for the existence of the resources loaded by the request in the shared HTTP and the DNS cache.
XSS worms exploit a security vulnerability known as cross site scripting (or XSS for short) within a website, infecting users in a variety of ways depending on the vulnerability. Such site features as profiles and chat systems can be affected by XSS worms when implemented improperly or without regard to security. Often, these worms are specific ...
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.
The example attack consists of defining 10 entities, each defined as consisting of 10 of the previous entity, with the document consisting of a single instance of the largest entity, which expands to one billion copies of the first entity.
Insecure direct object reference (IDOR) is a type of access control vulnerability in digital security. [1]This can occur when a web application or application programming interface uses an identifier for direct access to an object in an internal database but does not check for access control or authentication.
