CVE-2026-19670 Incorrect Authorization in CISA Malcolm
Malcolm's nginx Lua role-based access control RBAC layer decides whether an authenticated user may reach a role-restricted path e.g. /htadmin, /auth, /adminlogin, /arkime/api/esadmin, NetBox, upload endpoints by pattern-matching the raw, percent-encoded request URI. Nginx itself, however, selects...
CVE-2026-19670
Malcolm's nginx Lua RBAC layer pattern-matches the raw percent-encoded URI while nginx routes using the decoded URI, allowing an authenticated low-privilege user to access admin-only paths via encoded URLs like /%68tadmin.php. CVSS 5.4 (MEDIUM); no in-the-wild exploitation reported. No patch vers...
CVE-2026-63177 Malcolm Vulnerable to Authorization Bypass via URI Normalization Differential in Nginx Lua RBAC
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.requesturi, while Nginx itself routes requests using the normalized path. An authenticated low-privilege user can...

CVE-2026-63177
What is affected: Malcolm (network traffic analysis tool suite). The issue is in the Nginx OpenResty Lua RBAC layer prior to v26.07.0, where RBAC evaluates the unnormalized ngx.var.request_uri while Nginx routes on the normalized path. Root cause: URI normalization mismatch allows a low-privilege...
