Name of the Vulnerable Software and Affected Versions LXD (affected versions not specified)
Description An authorization bypass allows an authenticated attacker to circumvent security restrictions of a target project during cross-project instance migrations. By using the 'POST /1.0/instances/{name}' endpoint with the parameters migration, project, and target, the destination node fails to perform project restriction checks because the request is processed as an internal cluster notification. This allows an attacker to implement disallowed instance configurations within a restricted project.
Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
