Summary
Slim Select versions 2.0 through 2.9.0 are vulnerable to cross-site scripting (XSS). The createOption() function assigns user-provided text to innerHTML without sanitization, allowing attacker-executed JavaScript.
Risk Assessment
Organizations using Slim Select to dynamically generate lists from unsanitized user input risk session hijacking, data theft, or other XSS attacks.
Recommendation
Immediately stop using Slim Select versions 2.0-2.9.0 until a patch is released. As a temporary workaround, manually sanitize all user input before passing it to the library.
Original NVD description (English source)
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. At this time, no patch is available.
