Who should care

Defenders responsible for securing iFlytek Astron Agent deployments should be aware of this vulnerability and take steps to verify the affected versions and secure the workflow resume endpoint.

Why it matters

The CVE-2026-108864 vulnerability in iFlytek Astron Agent through version 1.1.2 allows authenticated applications to resume other applications' paused workflows, potentially breaking cross-tenant isolation. Defenders should prioritize verifying the affected versions and securing the workflow resume endpoint.

• Defenders need to verify the affected versions of iFlytek Astron Agent and ensure that the workflow resume endpoint is properly secured to prevent unauthorized access.
• Cross-tenant isolation breaches could occur if the vulnerability is exploited.
• Defenders should monitor workflow resume activity for suspicious behavior to detect potential exploitation.
• Remediation priority is medium, as the vulnerability has a low CVSS score but could still have significant impacts if exploited.

Technical summary

The iFlytek Astron Agent through version 1.1.2 contains an insecure direct object reference vulnerability that allows authenticated applications to resume other applications' paused workflows by supplying their event_id to the POST /workflow/v1/resume endpoint. This can be exploited to inject resume content into victim workflows and read their continuation output stream, potentially breaking cross-tenant isolation.

Defensive priority

Defenders should prioritize verifying the affected versions of iFlytek Astron Agent and ensuring that the workflow resume endpoint is properly secured to prevent unauthorized access.

Recommended defensive actions

• Verify the version of iFlytek Astron Agent and ensure it is up-to-date
• Restrict access to the /workflow/v1/resume endpoint to prevent unauthorized access
• Monitor workflow resume activity for suspicious behavior
• Implement additional security measures to prevent cross-tenant isolation breaches
• Review compensating controls for exposed systems while remediation is scheduled and verified
• Check relevant monitoring, detection, and logs for exposed assets that need extra review
• Track exceptions, retest remediated assets, and close the item only after evidence is documented
