CVE-2025-3653 Overview
CVE-2025-3653 is an improper access control vulnerability affecting the Petlibro Smart Pet Feeder Platform versions up to 1.7.31. The vulnerability allows unauthorized device manipulation by accepting arbitrary serial numbers without ownership verification. Attackers can control any device by sending serial numbers to device control APIs to change feeding schedules, trigger manual feeds, access camera feeds, and modify device settings without proper authorization checks.
Critical Impact
Unauthorized attackers can remotely control any Petlibro Smart Pet Feeder device, potentially disrupting pet feeding schedules, accessing private camera feeds, and modifying device configurations without any authentication or ownership verification.
Affected Products
- Petlibro Smart Pet Feeder Platform versions up to 1.7.31
- Petlibro mobile application with device control APIs
- IoT devices connected to the Petlibro cloud platform

Technical Details for CVE-2025-3653
Vulnerability Analysis
This improper access control vulnerability (CWE-612) stems from the Petlibro Smart Pet Feeder Platform's failure to implement proper authorization checks when processing device control requests. The platform's API endpoints accept arbitrary serial numbers without verifying that the requesting user has legitimate ownership or access rights to the specified device.
The vulnerability is exploitable over the network without requiring any prior authentication, allowing attackers to enumerate device serial numbers and send control commands to any device registered on the platform. This affects the confidentiality, integrity, and availability of affected devices, as attackers can view camera feeds (confidentiality), modify feeding schedules and settings (integrity), and disrupt normal device operation (availability).
Root Cause
The root cause of this vulnerability lies in missing ownership verification within the device control API endpoints. When a user sends a request to control a device, the platform fails to validate whether the authenticated user (or unauthenticated requester) has the authority to manage the specified device. This architectural flaw allows any party with knowledge of a device's serial number to issue commands as if they were the legitimate owner.
Attack Vector
The attack vector for CVE-2025-3653 is network-based, requiring no authentication or user interaction. An attacker can exploit this vulnerability by:
- Identifying or enumerating valid Petlibro device serial numbers
- Sending crafted API requests to device control endpoints with arbitrary serial numbers
- Executing unauthorized actions including modifying feeding schedules, triggering manual feeds, accessing camera feeds, and changing device settings
The vulnerability allows complete device takeover without any ownership verification, making it particularly dangerous for IoT devices that may affect pet welfare.

Detection Methods for CVE-2025-3653
Indicators of Compromise
- Unexpected changes to pet feeding schedules or device configurations
- Unauthorized manual feed triggers appearing in device activity logs
- Unknown IP addresses or sessions accessing device camera feeds
- API requests containing serial numbers for devices not owned by the authenticated user
Detection Strategies
- Monitor API logs for requests targeting device serial numbers that don't match registered user accounts
- Implement anomaly detection for unusual patterns of device control commands
- Review authentication logs for requests to device control endpoints without proper session tokens
- Track geographic anomalies in device access patterns
Monitoring Recommendations
- Enable comprehensive logging on all device control API endpoints
- Implement rate limiting on API endpoints to detect enumeration attempts
- Set up alerts for bulk API requests targeting multiple device serial numbers
- Monitor network traffic for unusual patterns of requests to Petlibro cloud services
How to Mitigate CVE-2025-3653
Immediate Actions Required
- Contact Petlibro support to inquire about available firmware and platform updates
- Review device activity logs for any suspicious or unauthorized actions
- Consider temporarily disconnecting devices from the network if critical feeding schedules must remain unchanged
- Change account passwords and enable any available two-factor authentication
Patch Information
No vendor patch information is currently available in the CVE data. Users should monitor the VulnCheck Security Advisory and Petlibro's official channels for security updates.
Workarounds
- Implement network segmentation to isolate IoT devices from critical network resources
- Use a dedicated IoT network with firewall rules to restrict outbound connections
- Monitor device behavior manually and maintain backup feeding methods for pets
- Consider using devices only in local/offline mode if supported by the hardware
# Network segmentation example for IoT devices
# Create a separate VLAN for IoT devices with restricted access
# Example iptables rules to limit IoT device communication
