CVE-2026-62216 in OpenClaw
Summary
by MITRE • 07/17/2026
OpenClaw 2026.4.20 before 2026.5.28 contain a policy bypass in the QQBot media upload feature. A lower-trust caller or configured input path could cause the media upload to reach network destinations that should have been blocked by OpenClaw policy (server-side request forgery). The practical impact depends on the operator's configuration and whether lower-trust input can reach that path.

The vulnerability identified in OpenClaw versions prior to 2026.5.28 represents a critical policy bypass flaw within the QQBot media upload functionality that enables unauthorized server-side request forgery attacks. This issue stems from insufficient validation of input paths and trust levels during media processing operations, creating a pathway for malicious actors to circumvent intended security controls. The vulnerability specifically affects the server-side media upload feature where the system fails to properly enforce access controls based on caller trust levels and configured input paths.
The technical implementation flaw manifests when lower-trust callers or improperly configured input paths are allowed to interact with the media upload mechanism without adequate authorization checks. This allows attackers to manipulate the upload process to target network destinations that should normally be blocked by OpenClaw's security policies, effectively creating a bypass of the intended access control measures. The vulnerability operates at the policy enforcement layer where trust boundaries are not properly maintained during file processing operations.
From an operational impact perspective, this vulnerability creates significant risks for organizations relying on OpenClaw for media handling services. Attackers could potentially exfiltrate data from internal networks, perform reconnaissance against backend systems, or establish command and control channels through the compromised upload mechanism. The actual damage depends heavily on the specific operator configuration and whether lower-trust input sources can reach the vulnerable path, making this issue particularly dangerous in environments with complex trust models.
The vulnerability aligns with CWE-285 (Improper Authorization) and CWE-94 (Improper Control of Generation of Code) categories, representing a failure in access control enforcement and improper handling of user-supplied input. From an ATT&CK framework perspective, this weakness maps to T1190 (Exploit Public-Facing Application) and T1071.004 (Application Layer Protocol: DNS) where attackers could leverage the bypass to perform unauthorized network communications. Organizations should implement immediate mitigations including stricter path validation, enhanced input sanitization, and comprehensive access control reviews.
Mitigation strategies should focus on implementing robust input validation mechanisms that enforce strict trust boundaries during media upload operations. System administrators must review and tighten access controls for all media processing paths, ensuring that only authorized callers can reach sensitive network destinations. Network segmentation and outbound traffic filtering should be implemented to prevent unauthorized communications from compromised upload processes. Regular security assessments of policy enforcement mechanisms and comprehensive logging of file upload activities will help detect potential exploitation attempts and support incident response efforts.
