CVE-2026-116194

Rclone from 1.52.0 before 1.75.2 contains a cross-site request forgery vulnerability in the pCloud backend's localhost OAuth callback, which disables the state check and trusts the hostname parameter. Malicious web pages can send a stateless request to port 53682 during authorization, planting attacker tokens and API hosts so later transfers reach the attacker.
