CVE-2025-11183Public exploitNetwork attack vector

Stored XSS via unsanitized attribute fields

Published Oct 13, 2025 · Updated Oct 13, 2025

Stored XSS in the attribute table in QGIS QWC2 before 2025.08.14 allows remote authenticated users to execute JavaScript in other users' browsers. LayerInfoWindow.jsx passes attacker-controlled name or description content through addLinkAnchors and into dangerouslySetInnerHTML without encoding or sanitization. The attacker needs attribute-layer editing permission, and execution occurs when another user displays the poisoned layer, enabling session theft or page defacement.
