Which packages are affected by CVE-2026-22217?

CVE-2026-22217 affects the following packages: openclaw (npm). Ecosystems affected: npm.

How do I fix CVE-2026-22217?

Update openclaw to 2026.2.23 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2026-22217 is resolved across your whole dependency graph.

How do I detect CVE-2026-22217 in my npm dependencies?

Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for openclaw, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.

How do I mitigate CVE-2026-22217 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.

Is CVE-2026-22217 actively exploited in the wild?

No public exploit code has been indexed for CVE-2026-22217 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-2026-22217?

CVE-2026-22217 has an EPSS (Exploit Prediction Scoring System) score of 0.1%, placing it in the 3th 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.

What type of vulnerability is CVE-2026-22217?

CVE-2026-22217 is classified as CWE-829 (CWE-829). This weakness type describe the underlying flaw category, which helps determine the potential impact and the right class of mitigation.

When was CVE-2026-22217 published, and has it been updated?

CVE-2026-22217 was published on March 18, 2026 and was last updated on October 28, 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

Summary

shell-env fallback trusted prefix-based executable paths for $SHELL, allowing execution of attacker-controlled binaries in local/runtime-env influence scenarios.

Details

In affected versions, shell selection accepted either:

a shell listed in /etc/shells, or
any executable under hardcoded trusted prefixes (/bin, /usr/bin, /usr/local/bin, /opt/homebrew/bin, /run/current-system/sw/bin).

The selected shell was then executed as a login shell (-l -c 'env -0') for PATH/environment probing.

On systems where a trusted-prefix directory is writable (for example common Homebrew layouts under /opt/homebrew/bin) and runtime $SHELL can be influenced, this enabled attacker-controlled binary execution in OpenClaw process context.

The fix removes the trusted-prefix executable fallback and now trusts only shells explicitly registered in /etc/shells; otherwise it falls back to /bin/sh.
