Slim Select has potential Cross-site Scripting issue
Date: 2024-10
Affected: npm/slim-select
Attack vector: xss
Category: vulnerability-disclosure
Severity: Medium
CVE: CVE-2024-9440
CWE: CWE-79
CVSS: 5.4 (CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:L/I:L/A:N)

Slim Select 2.0 versions through 2.9.0 are affected by a potential cross-site scripting vulnerability. In select.ts:createOption(), the text variable from the user-provided Options object is assigned to an innerHTML without sanitation. Software that depends on this library to dynamically generate lists using unsanitized user-provided input may be vulnerable to cross-site scripting, resulting in attacker executed JavaScript. This vulnerability is fixed in 2.9.2.
