CVE-2025-3652
📋 TL;DR
The Petlibro Smart Pet Feeder Platform contains an information disclosure vulnerability that allows attackers to access private audio recordings of other users. By exploiting sequential audio IDs and insecure API endpoints, unauthorized users can assign and retrieve audio files belonging to any device. This affects all users of Petlibro Smart Pet Feeder Platform versions up to 1.7.31.

⚠️ Risk & Real-World Impact
Worst Case
Mass privacy breach where all user audio recordings become accessible to attackers, potentially revealing sensitive conversations, home activities, or pet-related information that could be used for social engineering or blackmail.
Likely Case
Targeted privacy violations where attackers access specific users' audio recordings, compromising personal privacy and potentially exposing household routines or conversations.
If Mitigated
Limited impact with proper access controls and monitoring, where only authorized users can access their own recordings and suspicious API activity is detected and blocked.
🎯 Exploit Status
Exploitation requires valid user authentication but then allows access to other users' data. The vulnerability is well-documented in public advisories.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: 1.7.32 or later
Vendor Advisory: Not publicly available
Restart Required: No
Instructions:
1. Contact Petlibro support for updated platform version. 2. Upgrade to version 1.7.32 or later. 3. Verify the /device/deviceAudio/use endpoint now validates user ownership before allowing audio assignment.
🔧 Temporary Workarounds
API Endpoint Restriction
allImplement server-side validation to ensure users can only assign audio recordings to devices they own
Not applicable - requires code changes
Rate Limiting and Monitoring
allImplement rate limiting on audio API endpoints and monitor for unusual access patterns
Not applicable - requires infrastructure changes
🧯 If You Can't Patch
- Implement strict access controls and audit logging for all audio-related API endpoints
- Consider disabling the audio recording feature until a patch can be applied
🔍 How to Verify
Check if Vulnerable:
Test if you can access the /device/deviceAudio/use endpoint with arbitrary audio IDs and retrieve audio URLs not belonging to your devicesCheck Version:
Check platform version in admin interface or contact Petlibro supportVerify Fix Applied:
Verify that the /device/deviceAudio/use endpoint now properly validates user ownership before allowing audio assignment operations📡 Detection & Monitoring
Log Indicators:
- Multiple failed audio assignment attempts
- Unusual patterns of audio ID requests
- Access to audio files from unexpected user accounts
Network Indicators:
- Unusual volume of requests to /device/deviceAudio/use endpoint
- Sequential audio ID requests from single IP
