{"id":"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/\u003coriginal_filename\u003e. 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.","aliases":["GHSA-m2pc-3q4q-w6jr"],"modified":"2026-08-28T11:30:18.341304230Z","published":"2026-08-25T17:34:58.892Z","database_specific":{"cna_assigner":"GitHub_M","cwe_ids":["CWE-434"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/55xxx/CVE-2026-55419.json"},"references":[{"type":"WEB","url":"https://github.com/pollen-robotics/reachy_mini/releases/tag/v1.8.2"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/55xxx/CVE-2026-55419.json"},{"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"},{"type":"FIX","url":"https://github.com/pollen-robotics/reachy_mini/commit/984c7723b3ec5da63f4e0a2bcf9f120ceb563e04"},{"type":"FIX","url":"https://github.com/pollen-robotics/reachy_mini/pull/1209"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/pollen-robotics/reachy_mini","events":[{"introduced":"0"},{"fixed":"984c7723b3ec5da63f4e0a2bcf9f120ceb563e04"},{"fixed":"3dc4c99b7dfd4bc8b197e0bebebb0ea2cd3cfd94"}],"database_specific":{"extracted_events":[{"introduced":"0"},{"fixed":"1.8.2"}],"source":["AFFECTED_FIELD","REFERENCES"]}}],"versions":["v1.8.1","v1.8.0rc1","v1.7.3","v1.7.2","v1.7.1","v1.7.0","v1.6.4","v1.6.3","v1.6.2","v1.6.1","v1.6.0","v1.5.1","v1.5.0","v1.4.1","v1.2.4","v1.2.2","v1.2.1","v1.2.0","v1.1.3","v1.1.2","v1.1.1","v1.0.0rc4","v1.0.0rc3","v0.1.1","v0.1.0"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-55419.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:N"}]}
