Summary

CVE-2026-32019 is a low-severity SSRF (CWE-918) vulnerability in Openclaw Openclaw. Its CVSS base score is 2.3 (Low).

Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked at the 11th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.

The strongest mitigations our analysis identified map to AC-4 (Information Flow Enforcement) and SI-10 (Information Input Validation) — see the control section below for these in your framework.

Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.

CVE-2026-32019 is a server-side request forgery (SSRF) vulnerability, classified as CWE-918, affecting OpenClaw versions prior to 2026.2.22. The issue stems from incomplete IPv4 special-use range validation in the isPrivateIpv4() function, which fails to properly block requests to RFC-reserved ranges. This flaw enables SSRF policy bypasses within the web_fetch functionality, allowing access to non-global addresses such as 198.18.0.0/15. The vulnerability carries a CVSS v3.1 base score of 7.4 (AV:N/AC:L/PR:L/UI:N/S:C/C:L/I:L/A:L) and was published on 2026-03-19.

Attackers with low privileges and network reachability to special-use IPv4 ranges can exploit this vulnerability over the network with low complexity and no user interaction required. By targeting the web_fetch functionality with crafted requests to reserved ranges, they can bypass SSRF protections, achieving low-impact confidentiality, integrity, and availability effects across a changed scope.

Mitigation requires upgrading to OpenClaw 2026.2.22 or later. Patches addressing the incomplete validation are available in the following GitHub commits: 333fbb86347998526dd514290adfd5f727caa6d9, 44dfbd23df453e51b71ef79a148c28c53e89168c, 71bd15bb4294d3d1b54386064d69cd0f5f731bd8, and f14ebd743cfc73f667fae80af70043d0ab1f88bd.

Mitigating Controls (NIST 800-53 r5) AI

AC-4 Information Flow Enforcement good match

Information flow enforcement can restrict which destinations the server is allowed to contact on behalf of users.

SI-10 Information Input Validation good match

Input validation directly stops untrusted URLs from being accepted and fetched without destination checks.

SC-7 Boundary Protection partial match

Boundary protection limits the network reach of server-initiated requests even if SSRF occurs.
