CVE-2026-25858
📋 TL;DR
This vulnerability allows unauthenticated attackers to reset passwords for any user account by exploiting a flawed OTP verification process in the password reset workflow. Attackers only need a victim's telephone number to take over accounts, affecting all users of vulnerable macrozheng mall installations.

⚠️ Risk & Real-World Impact
Worst Case
Complete compromise of all user accounts, including administrative accounts, leading to data theft, financial fraud, and system takeover.
Likely Case
Targeted account takeover of specific users for credential theft, data access, or privilege escalation within the application.
If Mitigated
Limited impact with proper network segmentation and monitoring, but still exposes user accounts to unauthorized access.
🎯 Exploit Status
Exploitation requires only HTTP requests to the vulnerable API endpoints. No authentication or special tools needed.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Unknown
Vendor Advisory: https://github.com/macrozheng/mall/issues/946
Restart Required: No
Instructions:
1. Monitor the GitHub repository for patches. 2. Apply any available updates to the mall-portal component. 3. Test the password reset functionality after patching.
🔧 Temporary Workarounds
Disable vulnerable password reset endpoint
allTemporarily disable the /api/sso/password/reset endpoint in the mall-portal application
Modify application configuration to remove or block access to the vulnerable endpoint
Implement network-level blocking
allBlock access to password reset API endpoints at firewall/WAF level
Add firewall rule to block /api/sso/password/* endpoints from external networks
🧯 If You Can't Patch
- Implement strong rate limiting on password reset requests
- Add multi-factor authentication for all password reset operations
🔍 How to Verify
Check if Vulnerable:
Test the password reset API endpoint at /api/sso/password/reset. If it returns OTP values in responses or allows reset with only telephone number and OTP, the system is vulnerable.Check Version:
Check the application version in the admin panel or configuration filesVerify Fix Applied:
Verify that password reset now requires additional verification beyond telephone number and OTP, and that OTP values are not exposed in API responses.📡 Detection & Monitoring
Log Indicators:
- Multiple failed password reset attempts from single IP
- Successful password resets without proper authentication
- Unusual patterns in /api/sso/password/reset endpoint access
Network Indicators:
- HTTP POST requests to /api/sso/password/reset with telephone number parameters
- Unusual volume of password reset requests
