CVE-2024-48910

A prototype pollution vulnerability was found in DOMPurify. This flaw allows a remote attacker to add or modify attributes of an object prototype. This issue can lead to the injection of malicious attributes used in other components or cause a crash by overriding existing attributes with ones of incompatible type.

The prototype pollution vulnerability in DOMPurify is considered a high-severity issue because it allows attackers to modify the prototype of built-in JavaScript objects, potentially impacting the entire application. This could lead to security risks, such as overwriting methods on fundamental objects like Object, Array, or Function, allowing attackers to manipulate application behavior, bypass security controls, or cause application crashes. Given that DOMPurify is a core library for sanitizing user input, an attacker exploiting this vulnerability could gain control over how sanitized content is processed, leading to the execution of malicious scripts or triggering other unintended behaviors across the application.
