GitHub Vulnerability Alerts

CVE-2019-8331

Versions of bootstrap prior to 3.4.1 for 3.x and 4.3.1 for 4.x are vulnerable to Cross-Site Scripting (XSS). The data-template attribute of the tooltip and popover plugins lacks input sanitization and may allow attacker to execute arbitrary JavaScript.

Recommendation

For bootstrap 4.x upgrade to 4.3.1 or later.
For bootstrap 3.x upgrade to 3.4.1 or later.
