Deeper analysis
CVE-2023-46998 is a cross-site scripting vulnerability, tracked as CWE-79, that affects Bootbox.js versions 3.2 through 6.0. The flaw resides in the alert(), confirm(), and prompt() functions, which fail to sanitize input and therefore permit a crafted payload to be rendered as executable script in the browser.
A remote attacker can trigger the issue without authentication by supplying malicious content to any of the three functions. Successful exploitation executes arbitrary JavaScript in the victim’s session, producing limited confidentiality and integrity impacts consistent with the reported CVSS 6.1 score.
The EPSS score for this CVE stands at 0.3892 with no material increase from its initial value, indicating steady but not sharply rising exploitation interest after disclosure.
