Authorization Bypass in Workflow Management Endpoints

iFlytek astron-agent through 1.1.1 contains an authorization bypass vulnerability in the copyFlow endpoint that fails to validate workflow ownership. Authenticated attackers can enumerate workflow identifiers and overwrite other tenants' workflows or copy private workflows to read their definitions.

Casky was already ahead

This CVE exploits attack patterns that Casky's 283matched skills already investigate — long before this vulnerability was disclosed. Claude's reasoning model maps these techniques to MITRE ATT&CK, so practitioners who ran these skills have already seen the threat behaviour in their findings.

Analysis

iFlytek astron-agent versions through 1.1.1 suffer from an authorization bypass vulnerability in the copyFlow endpoint that fails to properly validate workflow ownership before allowing copy or modification operations. This vulnerability allows authenticated attackers to enumerate workflow identifiers across tenants and either overwrite other organizations' workflows or exfiltrate private workflow definitions. The impact is significant because workflows often contain sensitive business logic, credentials, and configuration data—making this a direct path to data theft and system compromise for multi-tenant deployments. Any organization using astron-agent for workflow orchestration faces exposure of their automation assets and potential lateral movement across tenant boundaries.

Casky's 283 mapped skills leverage Claude's extended reasoning to identify the abuse patterns underlying TA0004 (Privilege Escalation) and TA0006 (Credential Access) techniques. Practitioners would see detections flagging: unauthorized copyFlow API calls with mismatched workflow ownership identifiers, repeated enumeration attempts of workflow IDs outside the caller's tenant scope, and write operations modifying workflows the authenticated user shouldn't have access to. Claude's reasoning engine correlates these signals across request sequences—distinguishing legitimate workflow sharing from systematic exploitation—and surfaces findings that highlight the authorization bypass root cause (missing ownership validation) alongside the attack chain. This enables practitioners to immediately understand both the technical flaw and its operational exploitation.
