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.\n\n## Remediation\n\nRefer to the linked advisories for vendor-supplied fixes and affected version ranges.\n\n## Package advisory (CVE-2026-62674)\n\nAffected packages:\n\n- `omnigent < 0.3.0`\n\nPatched in:\n\n- `omnigent 0.3.0`\n\nSource: https://osv.dev/vulnerability/GHSA-jrrm-9hc7-2v3h","depth":"midnight","depthScore":50,"depthScoreParts":{"impact":49.5,"likelihood":0.1,"exploitation":0,"ransomware":0},"changes":[]}
