    Cross-site Scripting (XSS)

    bootstrap is a popular front-end framework for faster and easier web development.

    Affected versions of this package are vulnerable to Cross-site Scripting (XSS) due to inadequate sanitization of the href attribute, belonging to an <a> tag, in the carousel component. An attacker can execute arbitrary JavaScript within the victim's browser by injecting malicious code into the data-slide or data-slide-to attributes.

    Notes:

    1. Exploiting this vulnerability is also possible when the data_target attribute doesn’t exist or can’t be found, allowing the bypass of the clickHandler functionality.

    How to fix Cross-site Scripting (XSS)?

    Upgrade bootstrap to version 5.0.0-beta1 or higher.
