{"id":"CVE-2026-55419","aliases":["GHSA-m2pc-3q4q-w6jr"],"url":"https://o3.security/vulnerability/CVE-2026-55419","summary":"Reachy Mini: Unrestricted Upload of File with Dangerous Type","details":"Reachy Mini is an SDK for controlling Reachy Mini robots. Prior to 1.8.2, the Reachy Mini daemon exposes the /api/media/sounds/upload endpoint implemented by the upload_sound method in src/reachy_mini/daemon/app/routers/media.py without authentication, file-extension checks, content validation, or size validation. The daemon binds to 0.0.0.0 by default and uses permissive CORS allow_origins=[\"*\"], allowing an unauthenticated network attacker to upload arbitrary file types that are written to /tmp/reachy_mini_sounds/<original_filename>. Malicious files can compromise stored-data integrity and can serve as a foothold when combined with other vulnerabilities. This issue is fixed in version 1.8.2.","published":"2026-08-25T17:34:58.892Z","modified":"2026-08-27T04:00:15.850601628Z","cvss":{"score":5.3,"severity":"MEDIUM","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:N"},"epss":null,"cisaKev":null,"exploitsKnown":null,"affectedPackages":[{"ecosystem":"PyPI","name":"reachy-mini","fixedVersion":"1.8.2"}],"fix":{"url":"https://github.com/pollen-robotics/reachy_mini/commit/984c7723b3ec5da63f4e0a2bcf9f120ceb563e04","label":"pollen-robotics/reachy_mini@984c772"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/55xxx/CVE-2026-55419.json"},{"type":"FIX","url":"https://github.com/pollen-robotics/reachy_mini/commit/984c7723b3ec5da63f4e0a2bcf9f120ceb563e04"},{"type":"FIX","url":"https://github.com/pollen-robotics/reachy_mini/pull/1209"},{"type":"WEB","url":"https://github.com/pollen-robotics/reachy_mini/releases/tag/v1.8.2"},{"type":"ADVISORY","url":"https://github.com/pollen-robotics/reachy_mini/security/advisories/GHSA-m2pc-3q4q-w6jr"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-55419"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-27T04:00:15.850601628Z"}}
