There is no fixed version for Debian:11 leaflet.

NVD Description

Note: Versions mentioned in the description apply only to the upstream leaflet package and not the leaflet package as distributed by Debian. See How to fix? for Debian:11 relevant fixed versions and status.

Leaflet versions up to and including 1.9.4 are vulnerable to Cross-Site Scripting (XSS) via the bindPopup() method. This method renders user-supplied input as raw HTML without sanitization, allowing attackers to inject arbitrary JavaScript code through event handler attributes (e.g., <img src=x onerror="alert('XSS')">). When a victim views an affected map popup, the malicious script executes in the context of the victim's browser session.
