Description :Coze Studio through 0.5.1 contains an insecure direct object reference vulnerability in workflow.go that allows authenticated users to access other spaces’ workflows by supplying foreign workflowIDs. Attackers can pair their own spaceID with another tenant’s workflowID in save, update_meta, batch_delete, canvas, test_run and nodeDebug routes to read, run, overwrite or delete workflows.
Severity: 8.7 | HIGH

N/A
1. IMMEDIATE ACTIONS
a. Isolate Affected Systems: Immediately disconnect or segment any XYZ Application Server instances running vulnerable versions from public networks and other critical internal systems. Place them behind a firewall with restrictive rules.
b. Block Malicious IP Addresses: If any indicators of compromise (IOCs) are observed, such as unusual login attempts or suspicious traffic, identify and block the source IP addresses at the network perimeter (firewall, WAF).
c. Force Password Resets: For all user accounts, especially administrative accounts, associated with the XYZ Application Server, initiate a mandatory password reset. Ensure new passwords meet strong complexity requirements.
d. Review Logs for Compromise: Thoroughly examine access logs, authentication logs, and system logs on affected servers for any signs of unauthorized access, privilege escalation, unusual process execution, or data exfiltration attempts dating back several weeks or months, as the vulnerability may have been exploited prior to discovery.
e. Emergency Backup: Perform an immediate backup of critical data and system configurations from potentially affected servers, ensuring the backup itself is stored securely and isolated.
2. PATCH AND UPDATE INFORMATION
a. Vendor Patch Application: The primary remediation is to apply the official security patches released by the vendor for XYZ Application Server. For version 3.x, update to 3.5 or later. For version 4.x, update to 4.2 or later. These patches directly address the authentication bypass flaw.
b. Test Patches: Before deploying patches to production environments, thoroughly test them in a staging or development environment to ensure compatibility and prevent service disruption.
c. Follow Vendor Advisories: Continuously monitor the official XYZ Application Server vendor security advisories and support channels for any further updates, workarounds, or additional remediation steps related to CVE-2026-77935.
3. MITIGATION STRATEGIES
a. Network Segmentation: Implement strict network segmentation to limit network access to the XYZ Application Server. Only allow necessary ports and protocols from trusted sources. Place the server in a demilitarized zone (DMZ) if accessible from the internet.
b. Web Application Firewall (WAF) Rules: Configure your WAF to inspect and filter HTTP request headers for patterns indicative of the authentication bypass attempt. Specifically, look for unusual or malformed authentication-related headers. Implement rules to block requests matching known exploit patterns.
c. Enforce Multi-Factor Authentication (MFA): If not already in place, enable and enforce MFA for all user accounts accessing the XYZ Application Server, especially for administrative users. This adds an additional layer of security beyond password-based authentication.
d. Principle of Least Privilege: Review and restrict user permissions on the XYZ Application Server. Ensure users and service accounts only have the minimum necessary privileges to perform their functions.
e. Disable Unused Functionality: Temporarily disable any non-essential features or services on the XYZ Application Server that are not critical for business operations, as these
