What is CVE-2026-41396?

OpenClaw versions prior to 2026.3.31 are susceptible to an environment variable override vulnerability. This flaw enables attackers to manipulate the workspace's .env files, allowing them to redefine the OPENCLAW_BUNDLED_PLUGINS_DIR environment variable. As a result, these alterations can compromise the integrity of plugin trust verification mechanisms, potentially enabling malicious users to inject harmful plugins by altering the designated trust root directory for bundled plugins. Users are advised to upgrade to the latest version to mitigate any risks associated with this vulnerability.
