Summary

CVE-2026-41297 is a medium-severity SSRF (CWE-918) vulnerability in Openclaw Openclaw. Its CVSS base score is 4.8 (Medium).

Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked at the 15th 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-2026-41297 is a server-side request forgery (SSRF) vulnerability (CWE-918) affecting OpenClaw versions prior to 2026.3.31. The issue resides in the marketplace plugin download functionality within the marketplace.ts module, which fails to validate or restrict redirect destinations during archive downloads. This allows attackers to manipulate redirects and force the server to make unauthorized requests to arbitrary internal or external resources. The vulnerability carries a CVSS v3.1 base score of 7.6 (AV:N/AC:L/PR:L/UI:R/S:C/C:H/I:L/A:N) and was published on 2026-04-21.

Attackers with low privileges (PR:L), such as authenticated users, can exploit this over the network (AV:N) with low complexity (AC:L) by tricking a user into interacting with a malicious link or request (UI:R). Successful exploitation changes the scope (S:C), enabling high confidentiality impact (C:H) through access to internal resources, such as metadata services or other backend systems, while having low integrity impact (I:L) and no availability impact (A:N). Remote attackers can thus redirect server requests to sensitive internal endpoints or external servers under their control.

Mitigation is available in OpenClaw 2026.3.31 via a patch documented in GitHub commit 2ce44ca6a1302b166a128abbd78f72114f2f4f52. Security practitioners should consult the GitHub Security Advisory (GHSA-vjx8-8p7h-82gr) and Vulncheck advisory for detailed remediation steps, including upgrade instructions and validation of redirect handling in marketplace.ts.

Mitigating Controls (NIST 800-53 r5) AI

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

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

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