Unauthenticated file write and deletion via path traversal
Published Sep 3, 2026 · Updated Sep 3, 2026
Path traversal in Eclipse aeriOS Self-orchestrator before 1.2.1 allows remote attackers to write or delete files through its REST API. Create, update, and delete handlers incorporate user-controlled resource identifiers into JSON file paths without rejecting traversal separators. The API requires no authentication, and impact is bounded by the service account's filesystem permissions, although the affected container has elevated privileges.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
