Summary
CVE-2026-26324 is a high-severity SSRF (CWE-918) vulnerability in Openclaw Openclaw. Its CVSS base score is 7.5 (High).
Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked at the 30.9th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog.
This vulnerability is AI-related — categorised as Enterprise AI Assistants; in the Supply Chain and Deployment risk domain.
The strongest mitigations our analysis identified are NIST 800-53 SI-10 (Information Input Validation) and AC-4 (Information Flow Enforcement).
Deeper analysis
CVE-2026-26324 is a server-side request forgery (SSRF) protection bypass vulnerability (CWE-918) in OpenClaw, a personal AI assistant. Versions prior to 2026.2.14 fail to properly block requests to loopback, private networks, or link-local metadata endpoints when full-form IPv4-mapped IPv6 literals are used, such as `0:0:0:0:0:ffff:7f00:1` which resolves to `127.0.0.1`. This flaw allows otherwise prohibited internal requests to evade the SSRF guardrails.
The vulnerability carries a CVSS v3.1 base score of 7.5 (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N), indicating it is exploitable over the network with low complexity, no privileges or user interaction required. Remote unauthenticated attackers can craft malicious requests using these IPv6 literals to trick OpenClaw into accessing restricted internal resources, potentially disclosing sensitive data with high confidentiality impact.
OpenClaw version 2026.2.14 addresses the issue with a targeted patch. Mitigation details are documented in the GitHub security advisory (GHSA-jrvc-8ff5-2f9f), the release notes for v2026.2.14, and the fixing commit (c0c0e0f9aecb913e738742f73e091f2f72d39a19). Security practitioners should upgrade to the patched version immediately.

Vulnerability details
OpenClaw is a personal AI assistant. Prior to version 2026.2.14, OpenClaw's SSRF protection could be bypassed using full-form IPv4-mapped IPv6 literals such as `0:0:0:0:0:ffff:7f00:1` (which is `127.0.0.1`). This could allow requests that should be blocked (loopback / private network /…
