CVE-2026-38465Network attack vector

Stored XSS via donor avatar tooltip text

Published Aug 25, 2026 · Updated Aug 25, 2026

Stored XSS in GazellePW allows remote authenticated users to inject JavaScript through the donor avatar tooltip text field. The donor configuration path stores avatar_mouse_over_text, and the avatar rendering path emits the saved value into tooltip output without context-appropriate encoding. An authenticated donor can persist script that executes in another user's browser when that user views the affected avatar, exposing data and actions available to that browser session.
