CyberRota Analysis
AI-GeneratedNginx versions prior to 26.07.0 are vulnerable due to improper role-based access control in the OpenResty Lua layer, which evaluates the raw request URI instead of the normalized path. This flaw allows authenticated low-privilege users to exploit path traversal segments, potentially gaining unauthorized access to restricted backends. Organizations using affected versions should prioritize updating to 26.07.0 to mitigate this high-severity vulnerability.

Original NVD Description
Malcolm is a network traffic analysis tool suite. Prior to version 26.07.0, role-based access control enforced in the Nginx OpenResty Lua layer evaluates the raw, unnormalized `ngx.var.request_uri`, while Nginx itself routes requests using the normalized path. An authenticated low-privilege user can prepend a traversal segment (for example `/x/../upload/...`) so that Nginx routes the request to a restricted backend while the Lua role check fails to match any rule and falls open, granting access it should deny. Version 26.07.0 fixes the issue.
