OpenC3 COSMOS provides the functionality needed to send commands to and receive data from one or more embedded systems. Prior to version 7.0.0-rc3, the Script Runner widget allows users to execute Python and Ruby scripts directly from the openc3-COSMOS-script-runner-api container. Because all the docker containers share a network, users can execute specially crafted scripts to bypass the API permissions check and perform administrative actions, including reading and modifying data inside the Redis database, which can be used to read secrets and change COSMOS settings, as well as read and write to the buckets service, which holds configuration, log, and plugin files. These actions are normally only available from the Admin Console or with administrative privileges. Any user with permission to create and run scripts can connect to any service in the docker network. This issue has been patched in version 7.0.0-rc3.

A critical SQL injection vulnerability (CWE-89) exists in OpenC3 COSMOS versions 6.7.0 up to but not including 7.0.0-rc3. The vulnerability is located in the Time-Series Database component, specifically in the tsdb_lookup function of the cvt_model.rb file, where user input is not properly sanitized before being included in a SQL query. This allows an attacker with limited privileges to execute arbitrary SQL commands, potentially leading to data deletion or compromise. The issue has been addressed and patched in version 7.0.

OpenC3 COSMOS provides the functionality needed to send commands to and receive data from one or more embedded systems. Prior to version 7.0.0, the Command Sender UI uses an unsafe eval() function on array-like command parameters, which allows a user-supplied payload to execute in the browser when sending a command. This creates a self-XSS risk because an attacker can trigger their own script execution in the victim’s session, if allowed to influence the array parameter input, for example via phishing. If successful, an attacker may read or modify data in the authenticated browser context, including session tokens in local storage. This issue has been patched in version 7.0.0.

OpenC3 COSMOS provides the functionality needed to send commands to and receive data from one or more embedded systems. Prior to versions 6.10.5 and 7.0.0-rc3, OpenC3 COSMOS contains a design flaw in the save_tool_config() function that allows saving tool configuration files at arbitrary locations inside the shared /plugins directory tree by supplying crafted configuration filenames. Although the implementation sufficiently mitigates standard path traversal attacks, by canonicalizing filename to an absolute path, all plugins share this same root directory. That enables users to create arbitrary file structures and overwrite existing configuration files within the shared /plugins directory. This issue has been patched in versions 6.10.5 and 7.0.0-rc3.

OpenC3 COSMOS provides the functionality needed to send commands to and receive data from one or more embedded systems. Prior to versions 6.10.5 and 7.0.0-rc3, the OpenC3 password change functionality allows a user to change their password without providing the old password, by accepting a valid session token instead. In assumed breach scenarios, this behaviour can be exploited by an attacker who has already obtained a valid session token, to gain persistence in hijacked account (including admin) and prevent legitimate users from accessing the account. This issue has been patched in versions 6.10.5 and 7.0.0-rc3.

CVE-2025-68271 is a critical remote code execution vulnerability in OpenC3 COSMOS versions 5.0.0 through 6.10.1. The flaw arises from improper neutralization of directives in dynamically evaluated code (eval injection) within the JSON-RPC API. An attacker can send specially crafted JSON-RPC requests that trigger Ruby's eval() function on attacker-controlled input before authorization checks occur, allowing unauthenticated remote code execution. This vulnerability has a CVSS score of 10.0, indicating maximum severity, and affects embedded systems management environments using OpenC3 COSMOS. The issue is fixed in version 6.
