CVE-2026-43527

OpenClaw < 2026.4.14 - Server-Side Request Forgery via Private Network Navigation

Published May 5, 2026 CVSS 4.0 · 6.3 Medium EPSS < 1% KEV · Not listed

Description

OpenClaw before 2026.4.14 contains a server-side request forgery vulnerability in browser SSRF policy that allows private-network navigation by default. Attackers can exploit this misconfiguration to access internal services or metadata endpoints through browser-driven requests.

Analysis

Technical impact

OpenClaw before 2026.4.14 has a server‑side request forgery flaw caused by a misconfigured browser SSRF policy that permits navigation to private‑network resources. The flaw can allow an attacker to access internal services or metadata endpoints, potentially exposing sensitive information. This weakness maps to CWE‑1188 and CWE‑918.

Affected Systems

The vulnerability affects OpenClaw installations running versions prior to 2026.4.14, operating on a Node.js environment.

Risk and Exploitability

The CVSS score of 6.3 indicates a moderate severity. The EPSS score is not available, so the current exploitation probability cannot be quantified. The vulnerability is not listed in the CISA KEV catalog. The likely attack vector is a browser that follows the default SSRF policy, enabling an attacker to trick the server into making requests to internal or metadata endpoints.

Affected Products

Default status is the baseline for the product, each version can override it (e.g. patched versions marked unaffected).

Remediation

No solution or workaround provided in the CVE record.

OpenCVE Recommended Actions

Upgrade OpenClaw to version 2026.4.14 or later, which removes the default private‑network navigation setting.
If an upgrade is not immediately possible, modify the browser SSRF policy configuration to disallow private‑network requests.
Segment internal services from the server’s network or implement network isolation to limit the impact of any potential SSRF exploitation.
