{"id":"CVE-2026-42087","state":"PUBLISHED","title":"OpenC3 COSMOS: SQL Injection in QuestDB Time-Series Data Base","description":"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.","publishedAt":"2026-05-04T17:18:02.965Z","updatedAt":"2026-05-05T12:46:14.311Z","severity":{"score":9.6,"label":"Critical","version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:N","source":"GitHub_M"},"assigner":"GitHub_M","products":["OpenC3 cosmos"],"affected":[{"vendor":"OpenC3","product":"cosmos","versions":[{"version":">= 6.7.0, < 7.0.0-rc3","status":"affected"}]}],"references":["https://github.com/OpenC3/cosmos/security/advisories/GHSA-v529-vhwc-wfc5","https://github.com/OpenC3/cosmos/commit/9ba60c09c8836a37a2e4ea67ab35fe403e041415","https://github.com/OpenC3/cosmos/releases/tag/v7.0.0-rc3"],"weaknesses":["CWE-89"],"ingestedAt":"2026-10-29T20:11:57.932Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/42xxx/CVE-2026-42087.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-42087","state":"PUBLISHED","datePublished":"2026-05-04T17:18:02.965Z","dateUpdated":"2026-05-05T12:46:14.311Z","assignerShortName":"GitHub_M","assignerOrgId":"a0819718-46f1-4df5-94e2-005712e83aaa","dateReserved":"2026-04-23T19:17:30.566Z"},"containers":{"cna":{"title":"OpenC3 COSMOS: SQL Injection in QuestDB Time-Series Data Base","descriptions":[{"lang":"en","value":"OpenC3 COSMOS provides the functionality needed to send commands to and receive data from one or more embedded systems.
