DescriptionCVE.org

OpenClaw before 2026.4.20 contains a server-side request forgery vulnerability in QQBot direct media upload that skips URL validation. Attackers can bypass SSRF protections by sending crafted image URLs to uploadC2CMedia and uploadGroupMedia endpoints to relay unintended requests.

AnalysisAI

Server-side request forgery in OpenClaw before 2026.4.20 allows unauthenticated remote attackers to relay unintended requests through QQBot direct media upload endpoints (uploadC2CMedia and uploadGroupMedia) by sending crafted image URLs that bypass SSRF protections. The vulnerability affects QQBot outbound media handling and does not expose arbitrary local files, but could allow attackers to make configured QQBot media delivery requests to unintended destinations.

Technical ContextAI

OpenClaw's QQBot extension implements direct media upload functionality through uploadC2CMedia and uploadGroupMedia API endpoints that accept image URLs for relay to QQ's media servers. The vulnerability exists in CWE-918 (Server-Side Request Forgery) where the direct-upload code path failed to apply the SSRF validation guard (resolvePinnedHostnameWithPolicy and fetchWithSsrFGuard from openclaw/plugin-sdk/ssrf-runtime) that was correctly implemented in the local download path. The fix introduces hostname resolution policy checks to block private/internal/special-use IP addresses (including 169.254.x.x metadata endpoints) and enforces HTTPS-only URLs before making upstream requests to QQ's media servers.

RemediationAI

Upgrade OpenClaw to version 2026.4.20 or later, which includes fix commit 49db424c8001f2f419aad85f434894d8d85c1a09. The patch adds SSRF validation guards (resolvePinnedHostnameWithPolicy and fetchWithSsrFGuard) to both uploadC2CMedia and uploadGroupMedia endpoints, blocks requests to private/internal IP ranges including AWS metadata endpoints (169.254.169.254), and enforces HTTPS-only direct-upload URLs. Organizations using prior versions should immediately update via npm. No workarounds are available for unpatched versions; network-level restrictions on outbound QQBot media requests can provide temporary defense-in-depth but do not substitute for patching.
