CVE-2025-71429 RVC-Boss CVE debrief

Who should care

Defenders responsible for GPT-SoVITS deployments, especially those with UVR5 WebUI exposed, should assess their exposure and prioritize remediation efforts. This includes operators, platform administrators, vulnerability management teams, and security teams who need to verify affected versions, assess exposure, and apply necessary mitigations. The critical severity of this vulnerability necessitates prompt action from these stakeholders to prevent unauth

Why it matters

This critical vulnerability in GPT-SoVITS allows unauthenticated attackers to execute OS commands, posing a significant risk to deployments with exposed UVR5 WebUI. Defenders should verify exposure, prioritize remediation, and monitor for suspicious activity.

• Unauthenticated command execution as the server user
• Potential for lateral movement within the network
• Need for verification of affected versions and exposure
• Priority for updating to a fixed version of GPT-SoVITS

Technical summary

The GPT-SoVITS project through version 20250606v2pro contains an OS command injection vulnerability in tools/uvr5/vr.py. This vulnerability allows unauthenticated attackers to execute commands via output folder paths by entering shell substitutions in the UVR5 WebUI output folder textboxes during mp3 or m4a export. The vulnerability's technical details indicate that it is a critical issue that requires immediate attention from defenders. The affected product context and defensive impact of this vulnerability should be carefully evaluated.

Defensive priority

Defenders should prioritize verifying and remediating this vulnerability in GPT-SoVITS deployments, especially in environments where UVR5 WebUI is exposed.

Recommended defensive actions

• Verify GPT-SoVITS deployments for UVR5 WebUI exposure and update to a fixed version if available.
• Restrict access to UVR5 WebUI output folder textboxes to prevent unauthenticated command injection.
• Monitor GPT-SoVITS logs for suspicious command execution activity.
• Review compensating controls for exposed systems while remediation is scheduled and verified.
• Check relevant monitoring, detection, and logs for exposed assets that need extra review.
• Track exceptions, retest remediated assets, and close the item only after evidence is documented.
• Confirm whether affected product deployments exist in managed environments and assign an owner for follow-up.

Evidence notes

The vulnerability is located in tools/uvr5/vr.py and allows attackers to execute commands as the server user by entering shell substitutions in the UVR5 WebUI output folder textboxes. Evidence is based on the CVE record and technical descriptions from the source item. Defenders should verify the affected version, assess exposure, and monitor for suspicious command execution activity. The vulnerability's impact is critical, and its exploitation could lead to significant operational disruptions.
