Bucket content disclosure via relative path traversal
Published Sep 17, 2024 · Updated Sep 18, 2024
Path traversal in Backstage TechDocs before 1.10.13 allows remote authenticated users to read unintended S3 or GCS bucket objects. The TechDocs backend uses an attacker-controlled documentation path to form a cloud-storage object key without keeping the resolved key inside the requested entity's prefix. The flaw is reachable only when TechDocs uses the AWS S3 or GCS publisher, and it bypasses Backstage permission checks without modifying or deleting stored content.

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.
