CVE-2025-2320: Springboot-openai-chatgpt Auth Bypass Flaw

CVE-2025-2320 is a critical authorization bypass vulnerability in Springboot-openai-chatgpt allowing remote attackers to circumvent authentication controls. This article covers technical details, impact, and mitigation.

Published: March 11, 2026

CVE-2025-2320 Overview

A critical improper authorization vulnerability has been discovered in the springboot-openai-chatgpt application developed by 274056675. The vulnerability exists in the submit function within the /api/blade-user/submit endpoint of the User Handler component. This flaw allows remote attackers to bypass authorization controls and potentially perform unauthorized actions on the affected system.

Critical Impact

Remote attackers can exploit improper authorization in the User Handler component to bypass access controls, potentially leading to unauthorized data access or modification without authentication.

Affected Products

  • 274056675 springboot-openai-chatgpt (commit e84f6f5)
  • springboot-openai-chatgpt version 2024-12-29 and potentially other rolling releases

Discovery Timeline

  • 2025-03-14 - CVE-2025-2320 published to NVD
  • 2025-10-22 - Last updated in NVD database

Technical Details for CVE-2025-2320

Vulnerability Analysis

This vulnerability is classified as CWE-266: Incorrect Privilege Assignment. The affected submit function in the /api/blade-user/submit endpoint fails to properly validate user authorization before processing requests. This improper authorization mechanism allows unauthenticated or insufficiently privileged users to access functionality that should be restricted.

The springboot-openai-chatgpt project follows a rolling release model, meaning continuous updates are pushed without formal version numbering. This makes it challenging for users to determine if they are running a vulnerable version. The vendor was contacted about this disclosure but did not respond, leaving users without official guidance or patches.

Root Cause

The root cause of CVE-2025-2320 lies in the insufficient authorization checks within the User Handler component. The submit function processes user requests at the /api/blade-user/submit endpoint without properly verifying whether the requester has appropriate privileges to perform the requested action. This is a classic case of broken access control where the application fails to enforce proper privilege boundaries between different user roles or between authenticated and unauthenticated users.

Attack Vector

The vulnerability can be exploited remotely over the network without requiring authentication or user interaction. An attacker can craft malicious requests to the /api/blade-user/submit endpoint to bypass authorization controls. The exploit has been publicly disclosed, increasing the risk of exploitation in the wild.

The attack typically involves sending HTTP requests directly to the vulnerable endpoint. Since the authorization check is flawed, the application processes these requests without validating whether the sender has appropriate permissions. This could allow attackers to submit user data, modify existing records, or perform other privileged operations depending on the functionality exposed by the endpoint.

Detection Methods for CVE-2025-2320

Indicators of Compromise

  • Unusual HTTP POST requests to /api/blade-user/submit from unexpected sources or IP addresses
  • Access logs showing repeated requests to the User Handler endpoints without proper session tokens
  • Database modifications or user account changes that cannot be attributed to legitimate administrative actions
  • Anomalous patterns in API access logs indicating automated exploitation attempts

Detection Strategies

  • Implement Web Application Firewall (WAF) rules to monitor and alert on suspicious requests to /api/blade-user/submit
  • Deploy API gateway logging to capture all requests to the affected endpoint for forensic analysis
  • Configure SIEM rules to detect unauthorized access patterns to the User Handler component
  • Enable application-level logging for all authorization decisions in the affected codebase

Monitoring Recommendations

  • Monitor API endpoint access logs for requests lacking proper authentication tokens
  • Set up alerts for bulk or automated requests to the vulnerable endpoint
  • Review database audit logs for unauthorized modifications to user records
  • Implement rate limiting on the affected endpoint to detect and prevent exploitation attempts

How to Mitigate CVE-2025-2320

Immediate Actions Required

  • Restrict network access to the /api/blade-user/submit endpoint using firewall rules or reverse proxy configurations
  • Implement additional authentication layers (e.g., API keys, OAuth) at the infrastructure level before requests reach the application
  • Consider temporarily disabling the affected endpoint if it is not critical to operations
  • Review application logs for signs of prior exploitation

Patch Information

No official patch is available from the vendor at this time. The vendor (274056675) was contacted about this disclosure but did not respond. Since springboot-openai-chatgpt uses a rolling release model, users should monitor the project's repository for any commits addressing authorization in the User Handler component. For technical details, refer to the VulDB entry and the CNBlogs security analysis.

Workarounds

  • Implement a reverse proxy or API gateway that enforces strict authentication before forwarding requests to the vulnerable endpoint
  • Add custom middleware or filter to validate authorization tokens before processing requests to /api/blade-user/submit
  • Deploy network segmentation to limit access to the application from trusted networks only
  • Consider using a Web Application Firewall (WAF) with custom rules to block exploitation attempts
bash
# Example: Nginx configuration to restrict access to vulnerable endpoint
location /api/blade-user/submit {
    # Allow only from trusted internal network
    allow 10.0.0.0/8;
    allow 192.168.0.0/16;
    deny all;
    
    # Require authentication header
    if ($http_authorization = "") {
        return 401;
    }
    
    proxy_pass http://backend;
}
