CVE-2026-64816

Full vulnerability record from the local CVENow database.

Description

RapidRAW before 1.6.0 does not validate the lutPath field in preset files before passing it to File::open() in lut_processing.rs. On Windows, a UNC path in lutPath causes an outbound SMB connection to an attacker-controlled host, leaking the victim's NTLMv2 credentials. The vulnerable code path is reachable through two vectors: community presets fetched automatically from the remote preset repository when the victim opens the Community tab, and individual preset files imported directly by the victim via the preset import feature (handle_import_presets_from_file in file_management.rs). The second vector does not require control of the community preset repository and is triggered when a user imports a preset file shared through Discord, forums, or similar channels.

En Windows, una ruta UNC en lutPath provoca una conexión SMB saliente a un host controlado por el atacante, filtrando las credenciales NTLMv2 de la víctima. La ruta de código vulnerable es accesible a través de dos vectores: preajustes de la comunidad obtenidos automáticamente del repositorio remoto de preajustes cuando la víctima abre la pestaña Comunidad, y archivos de preajustes individuales importados directamente por la víctima a través de la función de importación de preajustes (handle_import_presets_from_file en file_management.rs). El segundo vector no requiere control sobre el repositorio de preajustes de la comunidad y se activa cuando un usuario importa un archivo de preajustes compartido a través de Discord, foros o canales similares."
