Summary
OpenClaw: Windows media loaders accepted remote-host file URLs before local path validation
Windows local-media handling accepted remote-host file URLs and UNC-style paths before local-path validation, so network-hosted file targets could be treated as local content.

Code-Level Confirmation
- src/infra/local-file-access.ts now rejects remote-host file: URLs and UNC/network paths as non-local input.
- src/media/web-media.ts, src/media-understanding/attachments.normalize.ts, and src/agents/sandbox-paths.ts all route through the shared local-file guard.
OpenClaw thanks @RacerZ-fighting, @Fushuling for reporting.
Impact

Security releases
Kodem intelligence
Severity tells you how bad this could be in the worst case. It does not tell you whether you are exposed. Exploitability and impact are functions of runtime truth: whether the vulnerable code is present, reachable, and actually executes in your application. A vulnerable package can sit in your dependency tree and never run.
Kodem, an Intelligent Application Security platform, uses runtime intelligence to reveal which vulnerabilities actually execute in production, so teams prioritize the ones that genuinely matter. Kodem's runtime-powered SCA identifies whether this CVE is reachable in your applications.

- Is CVE-2026-34426 exploitable, and should I be worried? Whether CVE-2026-34426 is exploitable in your environment depends on whether the vulnerable code is present and reachable. A CVSS score is a worst-case rating; it does not account for your specific deployment, configuration, or usage patterns. Kodem, an Intelligent Application Security platform, uses runtime intelligence to show which vulnerabilities actually execute in production, so you can focus on the ones that represent real risk.

- What actually determines whether CVE-2026-34426 is exploitable, and how bad it is? Exploitability and impact are not fixed properties of a CVE. They depend on runtime truth: whether the vulnerable code is present, reachable, and actually executes in your application. A high CVSS score on a dependency that never runs is not the same as real risk. Kodem, an Intelligent Application Security platform, uses runtime intelligence to reveal which vulnerabilities actually execute in production, so teams prioritize the ones that genuinely matter.
