CVE-2026-62328: Missing Authorization in decolua 9Router
9Router through version 0.4.41 contain an unauthenticated information disclosure vulnerability that allows remote attackers to access sensitive user data by sending requests to unprotected API endpoints. Attackers can enumerate paginated request logs and retrieve complete AI conversation histories including system prompts, user messages, assistant responses, tool calls, and user email addresses by querying the request-logs and request-details API routes which lack authentication middleware.
AI Analysis
Technical Summary
CVE-2026-62328 affects decolua's 9Router through version 0.4.41. The vulnerability is due to missing authorization checks on certain API endpoints, allowing unauthenticated remote attackers to enumerate paginated request logs and retrieve sensitive information such as system prompts, user messages, assistant responses, tool calls, and user email addresses. The issue stems from the lack of authentication middleware on the request-logs and request-details API routes, enabling unauthorized data disclosure.
Potential Impact
An attacker can remotely access sensitive user data without authentication, including complete AI conversation histories and user email addresses. This exposure compromises user privacy and confidentiality of AI interactions. The vulnerability has a high severity score of 8.7 (CVSS 4.0), indicating significant impact if exploited.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. No official fix or patch information is provided. Until a patch is available, restrict access to the affected API endpoints or implement custom authentication controls to prevent unauthorized access.
