Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

Laravel's framework package (laravel/framework) is affected in versions below 12.69.0 and from 13.0.0 up to but not including 13.30.0. When APP_DEBUG is set to true, attacker-controlled input is passed to a Tippy.js tooltip with HTML enabled, which allows cross-site scripting (DOM-based) that triggers when a user hovers the mouse over the affected element. The fix is to upgrade to version 12.69.0 or 13.30.0.
