Arbitrary file write via unsanitized workspace name
Published Jun 17, 2026 · Updated Jun 17, 2026
Path traversal in Black Lantern Security BBOT 2.1.0 through 2.8.5 allows remote attackers to write arbitrary files via Postman API data. The postman_download save_workspace method joins the API-supplied workspace name directly to output_dir, so pathlib resolves traversal elements outside that directory. Exploitation requires a BBOT user to run the module against an attacker-controlled Postman workspace; writes occur with that user's filesystem permissions.

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.
