CVE-2025-27420Public exploitNetwork attack vector

Unauthenticated browser script execution via unencoded descriptions

Published Mar 3, 2025 · Updated Mar 4, 2025

Stored XSS in WeGIA before 3.2.16 allows remote attackers to execute scripts in users' browsers through a crafted descricao value. The atendido_parentesco_adicionar.php handler trims and stores descricao without neutralizing markup, and Profile_Atendido.php inserts the saved value into an option element without HTML encoding. Submission is reachable without a valid session because redirect paths did not terminate execution, while impact requires a user to open the affected profile page.
