{"id":"CVE-2026-85665","summary":"Bruno through 4.1.0 Arbitrary File Read via Unconfined Body File Path","details":"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.","modified":"2026-09-06T03:47:20.210858205Z","published":"2026-09-04T14:32:21.592Z","database_specific":{"cna_assigner":"VulnCheck","cwe_ids":["CWE-22"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/85xxx/CVE-2026-85665.json"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/85xxx/CVE-2026-85665.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-85665"},{"type":"ADVISORY","url":"https://www.vulncheck.com/advisories/bruno-3.4.2-arbitrary-file-read-via-unconfined-body-file-path"},{"type":"REPORT","url":"https://github.com/usebruno/bruno/issues/8230"},{"type":"PACKAGE","url":"https://github.com/usebruno/bruno"},{"type":"ARTICLE","url":"https://github.com/usebruno/bruno/blob/v4.1.0/packages/bruno-cli/src/runner/prepare-request.js"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/usebruno/bruno","events":[{"introduced":"0"},{"fixed":"7d2af32d9c654e4ab48b8c39634f298db861eacb"}],"database_specific":{"extracted_events":[{"introduced":"0"},{"last_affected":"4.1.0"},{"fixed":"3.4.2"}],"source":["AFFECTED_FIELD","DESCRIPTION"]}}],"versions":["v3.4.1","v3.0.1","v3.0.0","v2.14.1","v2.14.0","v2.13.1","v2.13.0","v2.9.0","v2.8.0","v2.7.0","v2.4.0","v2.6.0","v2.6.1","v2.5.0","v2.3.0","v2.2.0","v2.1.0","v2.0.1","v1.40.0","v2.0.0","v1.39.1","v1.39.0","v1.38.1","v1.38.0","v1.37.0","v1.36.1","v1.36.0","v1.34.2","v1.34.1","v1.34.0","v1.33.1","v1.33.0","v1.32.1","v1.32.0","v1.31.0","v1.30.1","v1.30.0","v1.29.1","v1.29.0","v1.28.0","v1.27.0","v1.26.2","v1.26.1","v1.26.0","v1.25.0","v1.24.0","v1.23.1","v1.23.0","v1.22.0","v1.21.0","v1.20.4","v1.20.3","v1.20.2","v1.20.1","v1.20.0","v1.19.0","v1.18.1","v1.18.0","v1.17.0","v1.16.1","v1.16.0","v1.14.0","v1.13.1","v1.13.0","v1.12.3","v1.12.2","v1.12.1","v1.12.0","v1.11.0","v1.10.0","v1.9.0","v1.8.0","v1.7.1","v1.7.0","v1.6.1","v1.6.0","v1.5.1","v1.5.0","v1.3.2","v1.4.0","v1.3.1","v1.3.0","v1.2.0","v1.1.1","v1.1.0","v1.0.1","v1.0.0","v0.27.3","v0.27.2","v0.27.1","v0.27.0","v0.26.0","v0.25.0","v0.24.0","v0.23.0","v0.22.1","v0.22.0","v0.16.5","v0.21.1","v0.21.0","v0.20.0","v0.16.3","v0.19.0","v0.18.0","v0.17.0","v0.16.6","v0.16.4","v0.16.2","v0.16.1","v0.16.0","v0.15.3","v0.15.2","v0.15.1","v0.15.0","v0.14.1","v0.14.0","v0.13.2","v0.13.1","v0.13.0","v0.12.2","v0.12.1","v0.12.0","v0.11.0","v0.10.2","v0.10.1","v0.10.0","v0.9.4","v0.9.3","v0.9.2","v0.9.1","v0.9.0","v0.8.2","v0.8.1","v0.8.0","v0.7.2","v0.7.1","v0.7.0","v0.6.1","v0.6.0","v0.5.0","v0.4.0","v0.3.0","v0.2.0","v0.1.0"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-85665.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:P/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N"}]}
