CVE-2026-85665

Bruno through 4.1.0 Arbitrary File Read via Unconfined Body File Path

Published Sep 4, 2026 CVSS 4.0 · 7.1 High EPSS < 1% KEV · Not listed
Description
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.
