CVE-2026-41294: OpenClaw has a CWD `.env` environment variable injection which bypasses host-env policy and allows config takeover

OpenClaw before 2026.3.28 loads the current working directory .env file before trusted state-dir configuration, allowing environment variable injection.

Should you act?

Normal patch cycle

No exploitation signal; fix it in your next routine update if you are affected. This signal is computed from CISA KEV, EPSS and CVSS data; it is not an editorial verdict.

  • No confirmed exploitation. It is not in CISA’s KEV catalog and CISA’s SSVC assessment records no known exploitation. That can change quickly after a public write-up; re-check if you are affected.
  • EPSS 0.2%, percentile 8: FIRST’s model estimates a 0.2% chance of exploitation activity in the next 30 days, higher than 8% of all scored CVEs (low). EPSS is a probability, not a verdict.
  • Needs local access needed. Lower urgency for most teams unless an attacker could already run code on the machine.
  • Only applies if your dependency tree includes openclaw (npm) <= 2026.3.24, fixed in 2026.3.28. Check your lockfile, including transitive dependencies.

What it is

OpenClaw before 2026.3.28 loads the current working directory .env file before trusted state-dir configuration, allowing environment variable injection. Attackers can place a malicious .env file in a repository or workspace to override runtime configuration and security-sensitive environment settings during OpenClaw startup.

From the GitHub advisory

Summary

OpenClaw loaded the current working directory .env before trusted state-dir configuration, allowing untrusted workspace state to inject host environment values.

Impact

A repository or workspace containing a malicious .env file could override runtime configuration and security-sensitive environment settings when OpenClaw started there.

Affected Component

Weakness type: CWE-15, CWE-426.

CVSS measures how bad a flaw is if exploited, not how likely exploitation is. Read it next to the exploitation data below.

Exploitation and urgency

  • CISA KEV: not listed (no confirmed in-the-wild exploitation known to CISA).
  • CISA SSVC assessment: exploitation none, automatable no, technical impact total.
  • FIRST EPSS (model of 2026-10-21): 0.19% probability of exploitation activity in the next 30 days; percentile 8.
