{"id":"CVE-2026-62674","state":"PUBLISHED","title":"Omnigent: Shared Agent Bundle Overwrite Leads to Authenticated Runner RCE","description":"Omnigent is an open-source AI agent framework and meta-harness for orchestrating coding agents. Prior to 0.3.0, PUT /sessions/{session_id}/agent checks LEVEL_EDIT permission for a session but does not reject a bound shared or template agent whose agent.session_id is None. An authenticated user with edit access to a session can replace that shared agent bundle through omnigent/server/routes/sessions.py, add a stdio MCP server, and cause later sessions that use the shared agent to launch an attacker-controlled command through omnigent/tools/mcp.py. The command executes with the Omnigent runner process permissions and can expose files, credentials, workspace data, internal services, and runner availability. This issue is fixed in version 0.3.0.","publishedAt":"2026-08-21T17:47:37.976Z","updatedAt":"2026-08-25T17:43:46.509Z","severity":{"score":9,"label":"Critical","version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:C/C:H/I:H/A:H","source":"GitHub_M"},"assigner":"GitHub_M","products":["omnigent-ai omnigent"],"affected":[{"vendor":"omnigent-ai","product":"omnigent","versions":[{"version":"< 0.3.0","status":"affected"}]}],"references":["https://github.com/omnigent-ai/omnigent/security/advisories/GHSA-jrrm-9hc7-2v3h","https://github.com/omnigent-ai/omnigent/pull/1418","https://github.com/omnigent-ai/omnigent/commit/25a22dc9e6da4648d23749f0a589e47e6aed991b","https://github.com/omnigent-ai/omnigent/releases/tag/v0.3.0"],"weaknesses":["CWE-94"],"ingestedAt":"2026-10-29T20:12:32.778Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/62xxx/CVE-2026-62674.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-62674","state":"PUBLISHED","datePublished":"2026-08-21T17:47:37.976Z","dateUpdated":"2026-08-25T17:43:46.509Z","assignerShortName":"GitHub_M","assignerOrgId":"a0819718-46f1-4df5-94e2-005712e83aaa","dateReserved":"2026-07-14T20:22:04.395Z"},"containers":{"cna":{"title":"Omnigent: Shared Agent Bundle Overwrite Leads to Authenticated Runner RCE","descriptions":[{"lang":"en","value":"Omnigent is an open-source AI agent framework and meta-harness for orchestrating coding agents.
