MEDIUM 6.1EPSS 0.27%

Does this matter?

Lower severity and a low EPSS score (0.27%). Track it; it rarely justifies an emergency change on its own.

Description

Slink v1.4.9 allows stored cross-site scripting (XSS) via crafted SVG uploads. When a user views the shared image in a new browser tab, the embedded JavaScript executes. The issue affects both authenticated and unauthenticated users.
