Background
AngularJS is an open-source JavaScript framework developed by Google. It is widely used for building dynamic web applications. The framework provides a set of tools and features that enable developers to create single-page applications efficiently. However, AngularJS is vulnerable to a specific issue related to the improper sanitization of the [srcset] attribute in <source> HTML elements. This vulnerability allows attackers to bypass common image source restrictions, potentially leading to content spoofing attacks.
Vulnerability Detail
The vulnerability in AngularJS arises from the improper sanitization of the [srcset] attribute in <source> HTML elements. This attribute is used to specify a set of image sources and their corresponding sizes, allowing the browser to choose the most appropriate image to display based on the device's characteristics. However, due to the lack of proper sanitization, an attacker can manipulate the [srcset] attribute to bypass image source restrictions imposed by the application. This can lead to content spoofing attacks, where the attacker can trick users into viewing malicious or misleading content.
How To Fix
No fixed version is published for this vulnerability.

Workaround
There is no specific workaround provided for this vulnerability. However, developers can implement custom input validation and sanitization mechanisms to ensure that the [srcset] attribute is properly sanitized before being rendered in the HTML. This can help mitigate the risk of content spoofing attacks.
Conclusion
AngularJS is vulnerable to a content spoofing attack due to the improper sanitization of the [srcset] attribute in <source> HTML elements. As the project is end-of-life, no official fix is available. Developers should consider migrating to newer frameworks and follow best practices for input validation and sanitization to mitigate the risk of content spoofing attacks.
