{"id":"CVE-2026-42087","summary":"OpenC3 COSMOS: SQL Injection in QuestDB Time-Series Data Base","details":"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, including deleting data. This issue has been patched in version 7.0.0-rc3.","aliases":["GHSA-v529-vhwc-wfc5","PYSEC-2026-2244"],"modified":"2026-08-12T03:51:34.456338497Z","published":"2026-05-04T17:18:02.965Z","database_specific":{"cna_assigner":"GitHub_M","cwe_ids":["CWE-89"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/42xxx/CVE-2026-42087.json"},"references":[{"type":"WEB","url":"https://github.com/OpenC3/cosmos/releases/tag/v7.0.0-rc3"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/42xxx/CVE-2026-42087.json"},{"type":"ADVISORY","url":"https://github.com/OpenC3/cosmos/security/advisories/GHSA-v529-vhwc-wfc5"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-42087"},{"type":"FIX","url":"https://github.com/OpenC3/cosmos/commit/9ba60c09c8836a37a2e4ea67ab35fe403e041415"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/openc3/cosmos","events":[{"introduced":"75e3448c0363b457642080e1f9543b6ecca11f03"},{"fixed":"eb3e364e8f3d5a7ea68fd756625561192d0025f0"},{"introduced":"132648bad3b202bc5acf4d099d0af2341ec97047"},{"fixed":"9ba60c09c8836a37a2e4ea67ab35fe403e041415"},{"fixed":"c3ea3499cc01801122361524f6ccce2fdfbc35f0"}],"database_specific":{"cpe":["cpe:2.3:a:openc3:cosmos:*:*:*:*:open_source:*:*:*","cpe:2.3:a:openc3:cosmos:7.0.0:rc1:*:*:open_source:*:*:*","cpe:2.3:a:openc3:cosmos:7.0.0:rc2:*:*:open_source:*:*:*"],"extracted_events":[{"introduced":"6.7.0"},{"fixed":"7.0.0"},{"introduced":"7.0.0-rc1"},{"last_affected":"7.0.0-rc1"},{"introduced":"7.0.0-rc2"},{"last_affected":"7.0.0-rc2"}],"source":["CPE_RANGE","CPE_STRING","REFERENCES"]}}],"versions":["7.0.0-rc1","7.0.0-rc2","v7.0.0-rc3","v7.0.0-rc2","v7.0.0-rc1"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-42087.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:N"}]}
