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.","references":[{"reference_url":"https://api.first.org/data/v1/epss?cve=CVE-2026-42085","reference_id":"","reference_type":"","scores":[{"value":"0.00056","scoring_system":"epss","scoring_elements":"0.17833","published_at":"2026-06-11T12:55:00Z"}],"url":"https://api.first.org/data/v1/epss?cve=CVE-2026-42085"},{"reference_url":"https://github.com/OpenC3/cosmos","reference_id":"","reference_type":"","scores":[{"value":"4.3","scoring_system":"cvssv3.1","scoring_elements":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:L/A:N"},{"value":"MODERATE","scoring_system":"generic_textual","scoring_elements":""}],"url":"https://github.com/OpenC3/cosmos"},{"reference_url":"https://github.com/rubysec/ruby-advisory-db/blob/master/gems/openc3/CVE-2026-42085.yml","reference_id":"","reference_type":"","scores":[{"value":"4.3","scoring_system":"cvssv3.1","scoring_elements":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:L/A:N"},{"value":"MODERATE","scoring_system":"generic_textual","scoring_elements":""}],"url":"https://github.com/rubysec/ruby-advisory-db/blob/master/gems/openc3/CVE-2026-42085.yml"},{"reference_url":"https://nvd.nist.gov/vuln/detail/CVE-2026-42085","reference_id":"","reference_type":"","scores":[{"value":"4.3","scoring_system":"cvssv3.1","scoring_elements":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:L/A:N"},{"value":"MODERATE","scoring_system":"generic_textual","scoring_elements":""}],"url":"https://nvd.nist.gov/vuln/detail/CVE-2026-42085"},{"reference_url":"https://github.com/OpenC3/cosmos/commit/9957a9fa460c0c0cf5cdbf6a5931bbdd025246a5","reference_id":"9957a9fa460c0c0cf5cdbf6a5931bbdd025246a5","reference_type":"","scores":[{"value":"4.3","scoring_system":"cvssv3.1","scoring_elements":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:L/A:N"},{"value":"MODERATE","scoring_system":"generic_textual","scoring_elements":""},{"value":"Track","scoring_system":"ssvc","scoring_elements":"SSVCv2/E:N/A:N/T:P/P:M/B:A/M:M/D:T/2026-05-04T18:43:28Z/"}],"url":"https://github.com/OpenC3/cosmos/commit/9957a9fa460c0c0cf5cdbf6a5931bbdd025246a5"},{"reference_url":"https://github.com/OpenC3/cosmos/commit/e6efccbd148ba0e3361c5891027f2373aa140d42","reference_id":"e6efccbd148ba0e3361c5891027f2373aa140d42","reference_type":"","scores":[{"value":"4.3","scoring_system":"cvssv3.1","scoring_elements":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:L/A:N"},{"value":"MODERATE","scoring_system":"generic_textual","scoring_elements":""},{"value":"Track","scoring_system":"ssvc","scoring_elements":"SSVCv2/E:N/A:N/T:P/P:M/B:A/M:M/D:T/2026-05-04T18:43:28Z/"}],"url":"https://github.com/OpenC3/cosmos/commit/e6efccbd148ba0e3361c5891027f2373aa140d42"},{"reference_url":"https://github.com/advisories/GHSA-4jvx-93h3-f45h","reference_id":"GHSA-4jvx-93h3-f45h","reference_type":"","scores":[],"url":"https://github.com/advisories/GHSA-4jvx-93h3-f45h"},{"reference_url":"https://github.com/OpenC3/cosmos/security/advisories/GHSA-4jvx-93h3-f45h","reference_id":"GHSA-4jvx-93h3-f45h","reference_type":"","scores":[{"value":"4.3","scoring_system":"cvssv3","scoring_elements":""},{"value":"4.3","scoring_system":"cvssv3.1","scoring_elements":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:L/A:N"},{"value":"MODERATE","scoring_system":"generic_textual","scoring_elements":""},{"value":"Track","scoring_system":"ssvc","scoring_elements":"SSVCv2/E:N/A:N/T:P/P:M/B:A/M:M/D:T/2026-05-04T18:43:28Z/"}],"url":"https://github.com/OpenC3/cosmos/security/advisories/GHSA-4jvx-93h3-f45h"},{"reference_url":"https://github.com/OpenC3/cosmos/releases/tag/v6.10.5","reference_id":"v6.10.5","reference_type":"","scores":[{"value":"4.3","scoring_system":"cvssv3.1","scoring_elements":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:L/A:N"},{"value":"MODERATE","scoring_system":"generic_textual","scoring_elements":""},{"value":"Track","scoring_system":"ssvc","scoring_elements":"SSVCv2/E:N/A:N/T:P/P:M/B:A/M:M/D:T/2026-05-04T18:43:28Z/"}],"url":"https://github.com/OpenC3/cosmos/releases/tag/v6.10.5"},{"reference_url":"https://github.com/OpenC3/cosmos/releases/tag/v7.0.0-rc3","reference_id":"v7.0.0-rc3","reference_type":"","scores":[{"value":"4.3","scoring_system":"cvssv3.1","scoring_elements":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:L/A:N"},{"value":"MODERATE","scoring_system":"generic_textual","scoring_elements":""},{"value":"Track","scoring_system":"ssvc","scoring_elements":"SSVCv2/E:N/A:N/T:P/P:M/B:A/M:M/D:T/2026-05-04T18:43:28Z/"}],"url":"https://github.com/OpenC3/cosmos/releases/tag/v7.0.0-rc3"}],"fixed_packages":[{"url":"http://public2.vulnerablecode.io/api/packages/373508?format=json","purl":"pkg:gem/openc3@6.10.5","is_vulnerable":true,"affected_by_vulnerabilities":[{"vulnerability":"VCID-7tw5-qhgk-2bfd"},{"vulnerability":"VCID-ufxt-6f7u-pkbq"},{"vulnerability":"VCID-vh6a-17h9-vqgs"}],"resource_url":"http://public2.vulnerablecode.io/packages/pkg:gem/openc3@6.10.5"},{"url":"http://public2.vulnerablecode.io/api/packages/373489?format=json","purl":"pkg:gem/openc3@7.0.0-rc3","is_vulnerable":false,"affected_by_vulnerabilities":[],"resource_u

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, including deleting data.

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
