CVE-2026-32018 in OpenClaw
Summary
by MITRE • 03/20/2026
OpenClaw versions prior to 2026.2.19 contain a race condition vulnerability in concurrent updateRegistry and removeRegistryEntry operations for sandbox containers and browsers. Attackers can exploit unsynchronized read-modify-write operations without locking to cause registry updates to lose data, resurrect removed entries, or corrupt sandbox state affecting list, prune, and recreate operations.

The vulnerability identified as CVE-2026-32018 affects OpenClaw versions prior to 2026.2.19 and represents a critical race condition flaw within the registry management system. This vulnerability specifically impacts the concurrent operations of updateRegistry and removeRegistryEntry functions that govern sandbox containers and browsers. The fundamental issue stems from improper synchronization mechanisms that fail to protect shared registry resources during simultaneous read-modify-write operations. The absence of appropriate locking mechanisms creates a scenario where multiple threads or processes can access and modify the same registry entries concurrently, leading to unpredictable and potentially dangerous system states.
The technical implementation of this vulnerability manifests through unsynchronized access patterns that violate standard concurrency control principles. When multiple operations attempt to modify registry entries simultaneously, the lack of proper mutex or lock mechanisms allows for interleaved execution that can result in data loss or corruption. The race condition specifically occurs during operations that involve list, prune, and recreate functions, where the registry state becomes inconsistent due to the overlapping modifications. This flaw directly maps to CWE-362, which describes a race condition vulnerability where two or more threads access shared data concurrently and at least one of the threads performs a write operation. The vulnerability's impact extends beyond simple data inconsistency to potentially compromise the entire sandbox environment's integrity and operational reliability.
The operational impact of this vulnerability is significant for systems relying on OpenClaw's sandbox management capabilities. Attackers can exploit this weakness to cause registry updates to lose data, which may result in the removal of legitimate entries while simultaneously allowing malicious entries to be resurrected. This behavior creates a potential attack vector where adversaries can manipulate the registry state to bypass security controls or establish persistent access points within the sandboxed environment. The corruption of sandbox state affects critical system operations including list operations that may return incomplete or incorrect results, prune functions that fail to properly clean up resources, and recreate operations that may generate malformed or insecure configurations. These failures can lead to system instability, security breaches, and potential privilege escalation scenarios that compromise the overall security posture of the affected systems.
Mitigation strategies for this vulnerability must address the fundamental concurrency issues within the OpenClaw registry management system. The primary solution involves implementing proper synchronization mechanisms such as mutex locks, semaphores, or other concurrency control primitives to ensure that updateRegistry and removeRegistryEntry operations are mutually exclusive. The system should enforce atomic operations for registry modifications to prevent interleaved access patterns that cause data loss or corruption. Additionally, developers should implement proper resource management protocols that ensure registry entries are properly locked during modification operations and released appropriately to prevent deadlocks or resource starvation conditions. Organizations should also consider implementing monitoring and logging mechanisms to detect anomalous registry access patterns that may indicate exploitation attempts. The remediation approach aligns with ATT&CK technique T1562.001, which involves modifying registry values to maintain persistence or alter system behavior, as the vulnerability could enable similar malicious activities through registry manipulation. Regular security updates and patches should be deployed immediately to address this race condition, and system administrators should verify that all sandbox containers and browsers are running the patched version 2026.2.19 or later to ensure complete protection against this vulnerability.
