UNDERGOING ENRICHMENT

The CVE is currently being enriched by the Volerion team. The enrichment process results in the association of reference link tags, CVSS, and CPE applicability statement data.

Description

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.
