CVE-2025-71377

stoatchat (delta) versions before 20250210-1 (0.8.2) contain a logic error in the query messages route. When fetching messages 'nearby' another message, the database query can be given a message limit of zero, which the database interprets as 'no limit'. A remote unauthenticated attacker can craft nearby message fetch requests to download an entire channel's message history in a single expensive request, and can send many such requests in parallel, resulting in denial of service through resource exhaustion.

Summary		(es) Las versiones de stoatchat (delta) anteriores a 20250210-1 (0.8.2) contienen un error lógico en la ruta de consulta de mensajes. Al recuperar mensajes 'cercanos' a otro mensaje, la consulta de la base de datos puede recibir un límite de mensajes de cero, lo que la base de datos interpreta como 'sin límite'. Un atacante remoto no autenticado puede elaborar solicitudes de recuperación de mensajes cercanos para descargar el historial completo de mensajes de un canal en una única solicitud costosa, y puede enviar muchas de estas solicitudes en paralelo, lo que resulta en denegación de servicio por agotamiento de recursos.
