In versions before 3.90.0 and canary versions before 4.0.0-canary.34, an authenticated user who can update or delete uploads stored locally can cause file cleanup to remove unintended files outside the configured upload directory, resulting in data loss or service disruption. Deployments that restrict upload management to trusted users are less exposed.
