CVE-2026-77915 rconfig CVE debrief

Who should care

Organizations using rConfig Core versions prior to 8.2.10 should be aware of this critical vulnerability and take immediate action to remediate it. This includes upgrading to version 8.2.10 or later, reviewing and restricting access to the registration controller, monitoring for suspicious account registration attempts, and implementing additional authentication and authorization controls.

Technical summary

The rConfig Core 8.0.0 before 8.2.10 contains an authentication bypass vulnerability that allows unauthenticated attackers to self-register accounts with full Administrator privileges. This is caused by a duplicate bare Auth::routes() call in routes/web.php that re-enables the POST /register route after it was explicitly disabled. As a result, attackers can register a new account that is immediately authenticated with Admin-level access, enabling access to stored device credentials, user data, and API token issuance.

Defensive priority

Organizations using rConfig Core versions prior to 8.2.10 should prioritize immediate remediation due to the critical severity of this authentication bypass vulnerability.

Recommended defensive actions

• Immediately upgrade rConfig Core to version 8.2.10 or later
• Review and restrict access to the registration controller
• Monitor for suspicious account registration attempts
• Implement additional authentication and authorization controls
• Conduct a thorough review of stored device credentials, user data, and API token issuance
