What is CVE-2025-27608?

A self cross-site scripting vulnerability exists in Arduino IDE 2.x, stemming from improper handling of user input in the Additional Board Manager URLs field. This issue allows potential attackers to inject malicious scripts that are reflected back to the user via notification tooltips, due to inadequate output encoding. The risk intensifies based on the nature of the injected payload, leading to possible security breaches. Users are urged to upgrade to version 2.3.5 or later to mitigate this risk.
