CVE-2026-55419: CWE-434: Unrestricted Upload of File with Dangerous Type in pollen-robotics reachy_mini
Description
Reachy Mini SDK versions prior to 1.8.2 have an unauthenticated file upload vulnerability at the /api/media/sounds/upload endpoint. This endpoint lacks authentication, file extension checks, content validation, and size validation, allowing an attacker to upload arbitrary files. The daemon binds to all interfaces (0.0.0.0) and permits all CORS origins, increasing exposure. Uploaded files are stored in /tmp/reachy_mini_sounds/ with their original filenames. This can lead to integrity compromise of stored data and potentially serve as a foothold if combined with other vulnerabilities. The issue is fixed in version 1.8.2.

Technical Analysis
The Reachy Mini daemon prior to version 1.8.2 exposes an unauthenticated file upload endpoint (/api/media/sounds/upload) that does not validate file extensions, content, or size. The daemon listens on all network interfaces and allows permissive CORS origins, enabling unauthenticated remote attackers to upload arbitrary files to a temporary directory. This vulnerability corresponds to CWE-434 (Unrestricted Upload of File with Dangerous Type). Uploaded malicious files can compromise data integrity and may be leveraged in conjunction with other vulnerabilities for further exploitation. The vulnerability is addressed in Reachy Mini version 1.8.2.
Potential Impact
An unauthenticated network attacker can upload arbitrary files to the Reachy Mini daemon, potentially compromising the integrity of stored data. While there is no direct confidentiality or availability impact reported, the ability to upload malicious files may serve as a foothold for further attacks if combined with other vulnerabilities.
Mitigation Recommendations
Upgrade Reachy Mini to version 1.8.2 or later, where this vulnerability is fixed. The vendor advisory confirms the issue is resolved in 1.8.2. No additional mitigations are specified.
