Session hijacking via unescaped notification names
Published Apr 17, 2026 · Updated Apr 17, 2026
Stored XSS in WeGIA before 3.6.10 allows remote authenticated users to execute JavaScript in other users' browsers through crafted names. The Intercorrências notification interface inserts stored patient name or surname data into its Recentes and Histórico views without output encoding. Execution requires a victim to open an affected notification view and allows theft of session cookies or actions under the victim's account.
