BIT-KEYCLOAK-2026-15573 Keycloak-services: keycloak-services: authorization bypass via unnormalized uri matching in pathmatcher

A flaw was found in Keycloak's Authorization Services. The component responsible for matching request paths to security policies PathMatcher does not properly normalize URIs before comparison. By adding extra characters like a trailing slash or matrix parameters to a URL, an attacker can trick th...

EUVD-2026-64772

fast-uri is a URI parser for Node.js. Its custom parser for bracketed IPv6 literals does not validate the complete IPv6 grammar, so invalid trailing text in an authority can be silently discarded and a malformed attacker-controlled host is turned into a different valid IPv6 destination. For...

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...

CVE-2026-6321 fast-uri vulnerable to path traversal via percent-encoded dot segments

fast-uri decoded percent-encoded path separators and dot segments before applying dot-segment removal in its normalize and equal functions. Encoded path data was treated like real slashes and parent-directory references, so distinct URIs could collapse onto the same normalized path. Applications...
