{"cve":"CVE-2025-68271","nvd":{"published":"2026-01-13T19:16:14.673","modified":"2026-06-17T09:58:50.680","status":"Deferred","description":"OpenC3 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 string before calling authorize(), an unauthenticated attacker can trigger Ruby code execution even though the request ultimately fails authorization (401). This vulnerability is fixed in 6.10.2.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:H","score":10.0},"cwes":["CWE-95"],"references":["https://github.com/OpenC3/cosmos/security/advisories/GHSA-w757-4qv9-mghp"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:19:41.481987139+00:00"},"epss":{"cve":"CVE-2025-68271","score":0.00642,"percentile":0.5077,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-w757-4qv9-mghp","url":"https://osv.dev/vulnerability/GHSA-w757-4qv9-mghp","summary":"openc3-api Vulnerable to Unauthenticated Remote Code Execution","modified":"2026-02-03T02:56:30.118719Z","packages":[{"ecosystem":"RubyGems","name":"openc3","purl":"pkg:gem/openc3","ranges":[">=5.0.6 <6.10.2"],"fixed":["6.10.2"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
