A vulnerability has been identified in Bootstrap that exposes users to Cross-Site Scripting (XSS) attacks. The issue is present in the carousel component, where the data-slide and data-slide-to attributes can be exploited through the href attribute of an tag due to inadequate sanitization. This vulnerability could potentially enable attackers to execute arbitrary JavaScript within the victim's browser.
In Bootstrap starting in version 2.3.0 and prior to 3.4.0, as well as 4.x before 4.1.2, XSS is possible in the collapse data-parent attribute.
An unauthenticated attacker can craft the ___cfduid cookie value with base64 arbitrary code to be executed via eval(), which can be leveraged to execute arbitrary code on the target system. Note that there are three underscore characters in the cookie name. This is unrelated to the __cfduid cookie that is legitimately used by Cloudflare.
In Bootstrap, XSS is possible in the tooltip or popover data-template attribute.
In Bootstrap before 3.4.0, XSS is possible in the tooltip data-viewport attribute.
In Bootstrap before 3.4.0, XSS is possible in the affix configuration target property.
In Bootstrap, XSS is possible in the data-target attribute, a different vulnerability than CVE-2018-14041.
In Bootstrap starting in version 2.3.0 and prior to versions 3.4.0 and 4.1.2, XSS is possible in the data-container property of tooltip. This is similar to CVE-2018-14041.
