CVE-2026-4860: Unsafe Deserialization in wvp-GB28181-pro
Executive Summary
CVE-2026-4860 is a high severity vulnerability affecting software systems. It is classified as Unsafe Deserialization. Ensure your systems and dependencies are patched immediately to mitigate exposure risks.
Precogs AI Insight
"Precogs AI detected this vulnerability pattern in Unsafe Deserialization implementations. The pattern deviates from documented secure coding standards, suggesting a high likelihood of exploitation if unpatched."
Summary
A high-severity unsafe deserialization vulnerability (CVE-2026-4860) has been identified in wvp-GB28181-pro (a video surveillance platform implementing the GB28181 protocol), affecting versions up to 2.7.4. The application deserializes untrusted data without validation (CWE-502).
Technical Details
The issue is classified under CWE-502 (Deserialization of Untrusted Data) with input validation failures (CWE-20). The Java-based application accepts serialized objects from network requests and passes them directly to deserialization routines without type filtering or integrity checks.
Attackers exploit publicly available gadget chains (such as those in Apache Commons Collections, Spring Framework, or Jackson Databind) to construct serialized payloads that trigger arbitrary method invocations during the deserialization process.
Exploitation Context
- Vector: Remote / Network-based
- Authentication: Not required
- Complexity: Low
- Impact: High (Confidentiality, Integrity, and Availability)
As a video surveillance platform, wvp-GB28181-pro typically runs with elevated permissions and has network connectivity to physical camera infrastructure, making it a high-value target for lateral movement.
Remediation
Administrators of wvp-GB28181-pro should immediately:
- Upgrade to the latest patched version that implements deserialization filters and type whitelisting.
- Implement Java deserialization filters using
ObjectInputFilter(JEP 290) to restrict which classes can be instantiated during deserialization. - Replace native Java serialization with safer alternatives like JSON (without polymorphic type handling) for inter-service communication.
Precogs AI Integration
The Precogs AI Code Security Platform detects unsafe deserialization by tracing data flow from network input sources to deserialization sinks. Precogs identifies direct use of ObjectInputStream.readObject(), pickle.loads(), and similar patterns, flagging CWE-502 violations and recommending deserialization filters.
