CVE-2026-22181: OpenClaw < 2026.3.2 - DNS Pinning Bypass via Environment Proxy Configuration in web_fetch

• Severity: high (CVSS 7.6 v3.1)
• Exploited in the wild: not listed in CISA KEV
• EPSS: 0.2% probability of exploitation in the next 30 days
• Public exploit or detection template: none known
• Published: 2026-03-18 · updated 2026-06-17
• Weakness: CWE-918

Description

OpenClaw versions prior to 2026.3.2 contain a DNS pinning bypass vulnerability in strict URL fetch paths that allows attackers to circumvent SSRF guards when environment proxy variables are configured. When HTTP_PROXY, HTTPS_PROXY, or ALL_PROXY environment variables are present, attacker-influenced URLs can be routed through proxy behavior instead of pinned-destination routing, enabling access to internal targets reachable from the proxy environment.

Affected products

• OpenClaw: before 2026.3.2 — fixed in 2026.3.2

How to fix

Upgrade to a fixed version: OpenClaw 2026.3.2. Check the vendor advisory for mitigations.
