Unauthenticated image deletion via nonterminating redirect
Published Aug 12, 2025 · Updated Aug 12, 2025
Improper authentication in WeGIA before 3.4.8 allows remote attackers to delete stored images through a crafted unauthenticated request. The personalizacao_remover.php endpoint redirects unauthenticated sessions but does not terminate, then uses each imagem_n value to select and delete an unlinked image record. No account or user interaction is required; the attacker must identify image IDs, and linked records are not deleted.
