URL sanitization

Noun

DefinitionURL sanitization is the process of cleaning and validating Uniform Resource Locators (URLs) to remove or neutralize potentially malicious or malformed content. This practice is crucial in web development to prevent security vulnerabilities such as Cross-Site Scripting (XSS), SQL injection, or directory traversal attacks. By filtering out invalid characters, encoding special characters, and ensuring the URL adheres to expected formats and protocols, URL sanitization protects applications and users from harmful inputs. It ensures that any URL used or displayed by an application is safe, valid, and intended.

Example

"To protect against phishing attempts, the email client performs rigorous URL sanitization on all embedded links before displaying them to the user."
