Executing an XSS attack using... a library that counteracts XSS attacks ;)

The article titled 'Mutation XSS via MathML Mutation: DOMPurify 2.0.17 Bypass' explores a specific type of XSS (Cross-Site Scripting) attack that takes advantage of MathML mutations in conjunction with the popular library DOMPurify. The authors examine how the complexity and variety of MathML elements can be utilized to inject malicious code into applications that use this library for protection against such attacks. One of the main goals of the research is to demonstrate that even the most reputable sanitization solutions may have vulnerabilities that can be exploited by attackers. The tests conducted in the article reveal several potential vectors that allow bypassing DOMPurify's safeguards, highlighting the need for a more comprehensive understanding of data sanitization. Additionally, the article provides code examples illustrating how such attacks can be executed, which could be valuable for developers looking to improve the security of their applications. In conclusion, the article offers suggestions for better securing against similar attacks and emphasizes the importance of ongoing research and updates in security tools.
