{"id":"CVE-2026-77601","summary":"OpenC3 COSMOS: Authenticated OS command injection via the `pypi_url` setting","details":"OpenC3 COSMOS provides the functionality needed to send commands to and receive data from one or more embedded systems. From 5.12.0 until 7.3.0, an authenticated actor can write the pypi_url setting through set_setting at POST /openc3-api/api, then cause OpenC3::PluginModel.install_phase2 in openc3/lib/openc3/models/plugin_model.rb to interpolate the value into a shell command while installing a plugin with Python dependency metadata. Shell metacharacters in the setting are interpreted by the command shell, allowing arbitrary operating-system commands to run as the openc3 service user with access to Redis and bucket credentials. Open-source deployments permit any authenticated user to reach the affected operations, while Enterprise deployments require an administrator. This issue is fixed in version 7.3.0.","aliases":["GHSA-vp3w-52v9-q57f"],"modified":"2026-09-24T11:30:15.743166936Z","published":"2026-09-23T18:50:15.333Z","database_specific":{"cna_assigner":"GitHub_M","cwe_ids":["CWE-78"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/77xxx/CVE-2026-77601.json"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/77xxx/CVE-2026-77601.json"},{"type":"FIX","url":"https://github.com/OpenC3/cosmos/commit/be70d1d836c83c3b084e768e31a399312d4cbe0b"},{"type":"FIX","url":"https://github.com/OpenC3/cosmos/pull/3489"},{"type":"ADVISORY","url":"https://github.com/OpenC3/cosmos/security/advisories/GHSA-vp3w-52v9-q57f"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-77601"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/openc3/cosmos","events":[{"introduced":"a912ebbd272f6e4625a66e7dbec03763a279d710"},{"fixed":"92f8c99cc8ed704d2cf747832f09b72d64b6fa65"}],"database_specific":{"extracted_events":[{"introduced":"5.12.0"},{"fixed":"7.3.0"}],"source":"AFFECTED_FIELD"}}],"versions":["v7.2.1","v7.2.0","v7.1.1","v7.1.0","v6.10.4","v7.0.1","v7.0.0","v7.0.0-rc3","v7.0.0-rc2","v7.0.0-rc1","v6.10.3","v6.10.2","v6.10.1","v6.10.0","v6.9.2","v6.9.1","v6.9.0","v6.8.1","v6.7.0","v6.6.0","v6.5.1","v6.5.0","v6.4.2","v6.4.1","v6.4.0","v6.3.0","v6.2.1","v6.2.0","v6.1.0","v6.0.2","v6.0.1","v6.0.0","v5.20.0","v5.19.0","v5.18.0","v5.17.1","v5.17.0","v5.16.2","v5.16.1","v5.16.0","v5.15.2","v5.15.1","v5.15.0","v5.14.2","v5.14.1","v5.14.0","v5.13.0","v5.12.0"],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2026-77601.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H"}]}
