Summary

Incus before 6.0.7, from 6.1.0 before 7.0.2, and from 7.1.0 before 7.5.0 is affected. The GET /1.0/operations/{uuid} endpoint lacks an authorization check (CWE-862), so clients restricted to one project can read operations in other projects. An attacker with a restricted certificate and a known operation UUID can retrieve command lines, environment secrets, websocket secrets and trust enrolment tokens over the network with low privileges.

Description from the CNA

Incus before 6.0.7, 6.1.0 before 7.0.2, and 7.1.0 before 7.5.0 contains a missing authorization vulnerability in GET /1.0/operations/{uuid} that lets project-restricted clients read operations in other projects. Attackers holding a restricted certificate and a known operation UUID can retrieve command lines, environment secrets, websocket secrets, and trust enrolment tokens.
