Why it matters

CVE-2026-71801 is a critical vulnerability in s-pms SPMS-Server through v1.0 that allows remote authentication bypass. Defenders and administrators should assess exposure and prioritize remediation to prevent potential unauthorized access.

• Potential for remote authentication bypass
• Unauthorized access to protected backend APIs
• Possible exploitation by unauthenticated attackers
• Need for immediate verification and remediation

Technical summary

The s-pms SPMS-Server through v1.0 contains a hardcoded default access token secret within its core configuration file. A remote, unauthenticated attacker can locally forge valid administrative session tokens to completely bypass the authentication mechanism, gaining full unauthorized access to protected backend APIs. This vulnerability allows for potential unauthorized access and exploitation by unauthenticated attackers, emphasizing the need for immediate verification and remediation by defenders and administrators.

Defensive priority

High priority for immediate verification and remediation

Recommended defensive actions

• Verify the presence of the hardcoded access token secret in the production environment
• Override or remove the default access token secret
• Implement additional authentication mechanisms
• Monitor for potential unauthorized access
• 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

Evidence notes

The CVE record and NVD entry provide details about the hardcoded access token secret and the potential for authentication bypass.
