Base vector

AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:N/A:N

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.
