Background
The @tiptap/extension-link package is a popular extension for the Tiptap rich-text editor, enabling users to create and manage hyperlinks within their content. It is widely used in web applications to enhance text editing capabilities. However, prior to version 2.10.4, the package had a significant vulnerability that allowed unsanitized user input when setting or toggling links, making it susceptible to Cross-site Scripting (XSS) attacks.
Vulnerability Detail
Versions of the @tiptap/extension-link package before 2.10.4 are vulnerable to Cross-site Scripting (XSS) due to the lack of input sanitization. An attacker can exploit this vulnerability by injecting a malicious 'javascript:' URL payload into link attributes. When a user interacts with the link, the injected JavaScript code executes in the context of the application, potentially compromising user data and application integrity.

Workaround
If immediate updating is not feasible, consider implementing input validation and sanitization for any user-generated content that may be used in links. This can help mitigate the risk of XSS attacks until the package can be updated.
Conclusion
The @tiptap/extension-link package is vulnerable to Cross-site Scripting (XSS) in versions prior to 2.10.4. It is crucial for developers using this package to update to the latest version to mitigate the risk of XSS attacks. Implementing input validation can serve as a temporary measure until the update is applied.
