CVE-2025-3652 Overview
CVE-2025-3652 is an information disclosure vulnerability affecting the Petlibro Smart Pet Feeder Platform versions up to 1.7.31. This vulnerability allows unauthorized access to private audio recordings by exploiting sequential audio IDs and insecure assignment endpoints. Attackers can send requests to the /device/deviceAudio/use endpoint with arbitrary audio IDs to assign recordings to any device, then retrieve audio URLs to access other users' private recordings.
Critical Impact
Unauthorized attackers can access private audio recordings from any Petlibro Smart Pet Feeder user, compromising user privacy and potentially exposing sensitive household audio data.
Affected Products
- Petlibro Smart Pet Feeder Platform versions up to 1.7.31

Technical Details for CVE-2025-3652
Vulnerability Analysis
This vulnerability is classified under CWE-288 (Authentication Bypass Using an Alternate Path or Channel). The Petlibro Smart Pet Feeder Platform fails to properly validate whether a user has authorization to access or assign specific audio recordings. The platform uses sequential, predictable audio IDs without implementing proper ownership verification, allowing attackers to enumerate and access audio recordings belonging to other users.
The attack is network-based and requires no authentication or user interaction, making it particularly concerning for IoT device users who expect their private recordings to remain confidential.
Root Cause
The root cause of this vulnerability lies in the insecure implementation of the audio assignment endpoint (/device/deviceAudio/use). The platform does not verify that the requesting user owns or has permission to access the audio ID being requested. Combined with the use of sequential (predictable) audio IDs, this creates a classic Insecure Direct Object Reference (IDOR) condition that enables unauthorized data access.
Attack Vector
An attacker exploits this vulnerability by sending crafted HTTP requests to the /device/deviceAudio/use API endpoint. The attack flow involves:
- The attacker identifies the predictable pattern of audio IDs used by the platform
- The attacker sends requests with arbitrary audio IDs to the vulnerable endpoint
- The platform incorrectly assigns the audio recording to the attacker's device without ownership verification
- The attacker retrieves the audio URL and gains access to private recordings belonging to other users
This attack can be performed remotely over the network without any special privileges or user interaction, making it straightforward to execute at scale against the entire user base.
Detection Methods for CVE-2025-3652
Indicators of Compromise
- Unusual patterns of requests to /device/deviceAudio/use endpoint with sequential or enumerated audio IDs
- High volume of audio assignment requests from a single source IP or user account
- Access logs showing audio retrieval for IDs not associated with the requesting user's devices
- Anomalous spikes in audio URL generation or access patterns
Detection Strategies
- Implement API request rate limiting and monitoring for the /device/deviceAudio/use endpoint
- Deploy web application firewalls (WAF) with rules to detect enumeration attacks and IDOR attempts
- Enable comprehensive logging of all audio assignment and retrieval operations with user context
- Monitor for unusual patterns of sequential resource access that may indicate enumeration attacks
Monitoring Recommendations
- Configure alerts for excessive API requests targeting audio-related endpoints
- Implement anomaly detection for users accessing resources outside their normal ownership scope
- Establish baseline metrics for audio assignment operations and alert on significant deviations
- Review access logs regularly for signs of unauthorized audio ID enumeration
How to Mitigate CVE-2025-3652
Immediate Actions Required
- Upgrade Petlibro Smart Pet Feeder Platform to a version newer than 1.7.31 if available
- Implement network-level restrictions to limit access to the vulnerable API endpoint
- Review audio access logs to identify any potential unauthorized access that may have already occurred
- Consider temporarily disabling audio recording features until a patch is applied
Patch Information
Consult the vendor's official channels for patch availability. Technical details and security advisories are available from VulnCheck Security Advisory and BobdaHacker Blog Post.
Workarounds
- Implement additional access control layers at the network perimeter to restrict API access to trusted sources
- Deploy API gateway solutions that can enforce proper authorization checks on the vulnerable endpoint
- Monitor and rate-limit requests to the /device/deviceAudio/use endpoint to slow potential enumeration attacks
- Consider using a VPN or network segmentation to isolate IoT devices from untrusted networks
