CVE-2026-108263 iflytek CVE debrief

Who should care

Astron Agent administrators, especially those with multi-tenancy, should assess exposure and upgrade to version 1.1.2 or later. They should also review and restrict code-node execution paths, monitor for suspicious activity, and verify tenant isolation. Security teams should prioritize patching and monitor for potential cross-tenant data breaches and disruption of shared services.

Why it matters

CVE-2026-108263 allows for cross-tenant RCE in Astron Agent prior to 1.1.2. Defenders should upgrade and monitor multi-tenant environments.

• Potential for cross-tenant data breaches
• Disruption of shared services possible
• Elevation of privileges for low-privilege tenants
• Verification of tenant isolation required

Technical summary

Astron Agent's code-node execution was unsandboxed, allowing an authenticated low-privilege tenant to execute code as root in the core-workflow container. This was fixed in version 1.1.2. The vulnerability allows for cross-tenant RCE, enabling the reading or modification of other tenants' data and disruption of shared services. The issue is due to the default workflow code-node path through /console-api/workflow/code/run and /workflow/v1/run selecting LocalExecutor in core/workflow/engine/nodes/code/code_node.py when CODE_EXEC_TYPE is not explicitly changed.

Defensive priority

High priority for Astron Agent instances, especially those with multi-tenancy

Recommended defensive actions

• Upgrade to Astron Agent version 1.1.2 or later
• Review and restrict code-node execution paths
• Monitor for suspicious activity in multi-tenant environments
• Verify tenant isolation
• Check relevant monitoring, detection, and logs for exposed assets
• Track exceptions, retest remediated assets
• Confirm whether affected product deployments exist in managed environments
