AI Analysis
Technical Summary
CVE-2026-86777 is a missing authorization vulnerability in AlchemyCMS affecting versions prior to 7.4.16 and 8.x prior to 8.3.6. The vulnerability allows unauthenticated attackers to access the GET /api/nodes endpoint without proper authorization, enabling disclosure of all navigation nodes including restricted page names, URL paths, and internal URLs for all sites and languages managed by the CMS.
Potential Impact
The vulnerability enables unauthenticated attackers to obtain sensitive information about site navigation structure, including restricted page names and internal URLs. This information disclosure could aid attackers in further reconnaissance or targeted attacks but does not directly allow modification or deletion of data.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Since no official remediation level or patch links are provided, users should monitor the vendor's announcements for updates and apply any official fixes once available. Until then, consider restricting access to the /api/nodes endpoint via network controls or authentication proxies as a temporary mitigation.
