CVE-2026-42087CRITICAL | OpenC3 COSMOS: SQL Injection in QuestDB Time-Series Data BaseOpenC3 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… CWE-89May 4, 2026 | CVSS9.6v3.1 | EPSS0.323% | PoCs0 | SignalsNot listed in CISA KEVNo known ransomware useNo Nuclei templates | STIX |
CVE-2026-42086MEDIUM | OpenC3 COSMOS: Self-XSS in the Command SenderOpenC3 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… CWE-79May 4, 2026 | CVSS4.6v3.1 | EPSS0.2% | PoCs0 | SignalsNot listed in CISA KEVNo known ransomware useNo Nuclei templates | STIX |
CVE-2026-42085MEDIUM | OpenC3 COSMOS: Arbitrary write to plugins directory via path-traversed config filenamesOpenC3 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… CWE-23May 4, 2026 | CVSS4.3v3.1 | EPSS0.313% | PoCs0 | SignalsNot listed in CISA KEVNo known ransomware useNo Nuclei templates | STIX |
CVE-2026-42084HIGH | OpenC3 COSMOS: Hijacked session token can be used to reset password for persistenceOpenC3 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… CWE-620May 4, 2026 | CVSS8.1v3.1 | EPSS0.305% | PoCs0 | SignalsNot listed in CISA KEVNo known ransomware useNo Nuclei templates | STIX |
OpenC3 COSMOS: Permissions Bypass Provides User Access to Unassigned Administrative Actions via Script Runner Tool**Vulnerability Type: Execution with Unnecessary Privileges Attack type: Authenticated remote Impact: Data disclosure/manipulation, privilege escalation Affected components: The following docker images: • Openc3inc/openc3-COSMOS-script-runner-api** 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 per… CWE-250Apr 23, 2026 | CVSS-v3.1 | EPSS- | PoCs0 | SignalsNot listed in CISA KEVNo known ransomware useNo Nuclei templates | STIX | |
CVE-2025-68271CRITICAL | Unauthenticated Remote Code Execution in openc3-apiOpenC3 COSMOS provides the functionality needed to send commands to and receive data from one or more embedded systems. From 5.0.0 to 6.10.1, OpenC3 COSMOS contains a critical remote code execution vulnerability reachable through the JSON-RPC API. When a JSON-RPC request uses the string form of certain APIs, attacker-controlled parameter text is parsed into values using String#convert_to_value. For array-like inputs, convert_to_value executes eval(). Because the cmd code path parses the command … CWE-95Jan 13, 2026 | CVSS10.0v3.1 | EPSS0.556% | PoCs0 | SignalsNot listed in CISA KEVNo known ransomware useNo Nuclei templates | STIX |
CVE-2024-47529MEDIUM | OpenC3 COSMOS uses clear text storage of password/token (`GHSL-2024-129`)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. | CVSS4.8v4.0 | EPSS0.342% | PoCs0 | SignalsNot listed in CISA KEVNo known ransomware useNo Nuclei templates | STIX |
CVE-2024-46977MEDIUM | OpenC3 COSMOS allows a path traversal via screen controller (`GHSL-2024-127`)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. CWE-22Oct 2, 2024 | CVSS5.3v4.0 | EPSS0.912% | PoCs0 | SignalsNot listed in CISA KEVNo known ransomware useNo Nuclei templates | STIX |
CVE-2024-43795MEDIUM | OpenC3 COSMOS vulnerable to cross-site scripting in Login functionality (`GHSL-2024-128`)OpenC3 COSMOS provides the functionality needed to send commands to and receive data from one or more embedded systems. The login functionality contains a reflected cross-site scripting (XSS) vulnerability. This vulnerability is fixed in 5.19.0. Note: This CVE only affects Open Source Edition, and not OpenC3 COSMOS Enterprise Edition. CWE-79Oct 2, 2024 | CVSS5.1v4.0 | EPSS0.455% | PoCs0 | SignalsNot listed in CISA KEVNo known ransomware useNo Nuclei templates | STIX |
