Does this matter?

Lower severity and a low EPSS score (0.30%). Track it; it rarely justifies an emergency change on its own.

Description

User-controlled input is reflected into the HTML output without proper encoding on TP-Link Archer C60 v3, allowing arbitrary JavaScript execution via a crafted URL. An attacker could run script in the device web UI context, potentially enabling credential theft, session hijacking, or unintended actions if a privileged user is targeted.
