CVE-2026-12568: Path Traversal and Arbitrary File Write in BBOT postman_download Module

Vulnerability ID: CVE-2026-12568
CVSS Score: 6.5
Published: 2026-06-18

CVE-2026-12568 is a path traversal vulnerability (CWE-22) in the postman_download module of BBOT (Babbage Border Obsession Tool) version 2.1.0 through 2.8.5. The vulnerability allows an attacker to perform arbitrary file writes on the local machine running the BBOT scan via a maliciously named remote Postman workspace.

TL;DR

A path traversal vulnerability in BBOT's postman_download module allows remote attackers to execute arbitrary file writes using crafted Postman workspace names.

Mitigation Strategies

Upgrade BBOT to a version newer than 2.8.5
Apply path sanitization and canonical path validation checks to the postman_download module

Remediation Steps:

Identify installations running BBOT versions <= 2.8.5.
Execute pip install --upgrade bbot or update the dependency in your environment manager.
Verify the installation of version 2.8.6 or newer.
If updating is restricted, manually apply the path validation logic using pathlib's resolve() and is_relative_to() methods to the postman_download.py module.
