## What is CVE-2026-102279?

CVE-2026-102279 is a low-severity cross-site scripting vulnerability in laravel framework, published on 28 Sep 2026. An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.

### Official description

Laravel is a web application framework. Prior to 12.69.0 and 13.30.0, Laravel exception debug pages with APP_DEBUG=true pass attacker-controlled input to a Tippy.js tooltip configured with allowHTML true, enabling DOM-based cross-site scripting when a user hovers over the tooltip. This issue is fixed in versions 12.69.0 and 13.30.0.

Weakness: CWE-80 (Improper Neutralization of Script-Related HTML Tags in a Web Page)
