Summary		(es) Discourse es una plataforma de discusión de código abierto. Antes de las versiones 2025.12.2, 2026.1.1 y 2026.2.0, una inyección SQL en el filtrado de etiquetas de mensajes privados ('list_private_messages_tag') permite eludir las condiciones del filtro de etiquetas, lo que podría revelar metadatos de mensajes privados no autorizados. Las versiones 2025.12.2, 2026.1.1 y 2026.2.0 parchean el problema. No se conocen soluciones alternativas disponibles.
