# CVE-2026-85665

> 6.5 MEDIUM

## Beschreibung

Bruno versions through 4.1.0 fail to validate file paths in request body declarations, allowing attackers to read arbitrary local files by using parent-directory traversal segments. When a collection is executed, attackers can craft a request with a body:file path containing ../ sequences that resolve outside the collection directory, causing the application to read and exfiltrate arbitrary files to attacker-controlled endpoints.
