Which packages are affected by CVE-2026-6011?

CVE-2026-6011 affects the following packages: openclaw (npm). Ecosystems affected: npm.

How do I fix CVE-2026-6011?

Update openclaw to 2026.1.29 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2026-6011 is resolved across your whole dependency graph.

How do I detect CVE-2026-6011 in my npm dependencies?

Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for openclaw. O3's reachability analysis confirms whether the vulnerable code path is actually invoked in your application, so you act on real exposure instead of every transitive match.

How do I mitigate CVE-2026-6011 if there is no patch (or I can't update yet)?

If you can't upgrade right away: gate or disable the affected feature, validate untrusted input at the boundary, and avoid passing attacker-controlled data into the vulnerable path. O3's runtime protection blocks exploitation in production as an interim safeguard until the upgrade lands.

How does O3 Security protect against CVE-2026-6011?

O3 pinpoints whether CVE-2026-6011 is reachable in your code and exactly where to fix it, then blocks exploitation in production at runtime until the patched version is deployed.

Is CVE-2026-6011 actively exploited in the wild?

No public exploit code has been indexed for CVE-2026-6011 yet. This does not mean the vulnerability cannot be exploited — absence of public exploits does not imply safety. Apply the recommended fix and use O3 Security to monitor your exposure.

What is the EPSS score for CVE-2026-6011?

CVE-2026-6011 has an EPSS (Exploit Prediction Scoring System) score of 0.4%, placing it in the 35th percentile of all CVEs. EPSS is maintained by FIRST.org and estimates the probability that a vulnerability will be exploited in the wild within the next 30 days. This score indicates relatively lower exploitation probability, though the CVSS severity should still guide your patching priority.

When was CVE-2026-6011 published, and has it been updated?

CVE-2026-6011 was published on April 10, 2026 and was last updated on August 5, 2026. Advisory data evolves as severity scores, affected ranges, and exploit intelligence are revised — always check the latest version of the advisory before acting.

Description

A weakness has been identified in OpenClaw up to 2026.1.26. Affected by this issue is some unknown functionality of the file src/agents/tools/web-fetch.ts of the component assertPublicHostname Handler. Executing a manipulation can lead to server-side request forgery. The attack can be executed remotely. This attack is characterized by high complexity. The exploitation is known to be difficult. The exploit has been made available to the public and could be used for attacks. Upgrading to version 2026.1.29 can resolve this issue. This patch is called b623557a2ec7e271bda003eb3ac33fbb2e218505. Upgrading the affected component is advised.
