|---|---|---|---|---|---|---|
| CVE-2026-42088 | 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 Red | [email protected] | 9.6 | 0.02% | 2026-05-04 | 2026-05-13 |
| CVE-2026-42087 | OpenC3 COSMOS provides the functionality needed to send commands to and receive data from one or more embedded systems. From version 6.7.0 to before version 7.0.0-rc3, a SQL injection vulnerability exists in the Time-Series Database (TSDB) component of COSMOS. The tsdb_lookup function in the cvt_model.rb file directly places user-supplied input into a SQL query without sanitizing the input. As a result, a user can break out of the initial SQL statement and execute arbitrary SQL commands, includi | [email protected] | 9.6 | 0.02% | 2026-05-04 | 2026-05-08 |
| CVE-2026-42086 | 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 ph | [email protected] | 4.6 | 0.03% | 2026-05-04 | 2026-05-08 |
| CVE-2026-42085 | 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 | [email protected] | 4.3 | 0.04% | 2026-05-04 | 2026-05-08 |
| CVE-2026-42084 | 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 | [email protected] | 8.1 | 0.03% | 2026-05-04 | 2026-05-08 |
| CVE-2025-28389 | Weak password requirements in OpenC3 COSMOS v6.0.0 allow attackers to bypass authentication via a brute force attack. | [email protected] | 9.8 | 0.37% | 2025-06-13 | 2025-06-17 |
| CVE-2025-28388 | OpenC3 COSMOS before v6.0.2 was discovered to contain hardcoded credentials for the Service Account. | [email protected] | 9.8 | 0.54% | 2025-06-13 | 2025-10-27 |
| CVE-2025-28386 | A remote code execution (RCE) vulnerability in the Plugin Management component of OpenC3 COSMOS v6.0.0 allows attackers to execute arbitrary code via uploading a crafted .txt file. | [email protected] | 9.8 | 4.04% | 2025-06-13 | 2025-06-23 |
| CVE-2025-28384 | An issue in the /script-api/scripts/ endpoint of OpenC3 COSMOS before 6.1.0 allows attackers to execute a directory traversal. | [email protected] | 9.1 | 2.16% | 2025-06-13 | 2025-10-27 |
| CVE-2025-28382 | An issue in the openc3-api/tables endpoint of OpenC3 COSMOS before 6.1.0 allows attackers to execute a directory traversal. | [email protected] | 7.5 | 2.06% | 2025-06-13 | 2025-10-27 |
| CVE-2025-28381 | A credential leak in OpenC3 COSMOS before v6.0.2 allows attackers to access service credentials as environment variables stored in all containers. | [email protected] | 7.5 | 0.43% | 2025-06-13 | 2025-10-27 |
| CVE-2025-28380 | A cross-site scripting (XSS) vulnerability in OpenC3 COSMOS before v6.0.2 allows attackers to execute arbitrary web scripts or HTML via injecting a crafted payload into the URL parameter. | [email protected] | 6.1 | 0.29% | 2025-06-13 | 2025-10-27 |
| CVE-2024-47529 | OpenC3 COSMOS provides the functionality needed to send commands to and receive data from one or more embedded systems. OpenC3 COSMOS stores the password of a user unencrypted in the LocalStorage of a web browser. This makes the user password susceptible to exfiltration via Cross-site scripting (see GHSL-2024-128). This vulnerability is fixed in 5.19.0. This only affects Open Source edition, and not OpenC3 COSMOS Enterprise Edition. | [email protected] | 4.8 | 0.93% | 2024-10-02 | 2024-11-13 |
| CVE-2024-46977 | OpenC3 COSMOS provides the functionality needed to send commands to and receive data from one or more embedded systems. A path traversal vulnerability inside of LocalMode's open_local_file method allows an authenticated user with adequate permissions to download any .txt via the ScreensController#show on the web server COSMOS is running on (depending on the file permissions). This vulnerability is fixed in 5.19.0. | [email protected] | 5.3 | 1.15% | 2024-10-02 | 2024-10-31 |
| CVE-2024-43795 | OpenC3 COSMOS provides the functionality needed to send commands to and receive data from one or more embedded systems.
