Rclone pCloud OAuth Callback CSRF Vulnerability

Short explanation

The pCloud backend localhost OAuth callback in Rclone from 1.52.0 before 1.75.2 disables the state check and trusts the hostname parameter, resulting in a cross-site request forgery vulnerability [S0, S1].

Why does it matter?

Malicious web pages can send a stateless request to port 53682 during authorization to plant attacker tokens and API hosts, redirecting subsequent transfers to the attacker [S0, S1].

What should be done?

  • Follow vendor advisory guidance [S0]
  • Apply updates released for affected versions [S0, S1]
  • Monitor OAuth callback operations [S0, S1]

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.
