CVE-2026-58404

Hugo is a static site generator. From v0.162.0 through v0.163.0, the default security.http.urls policy denies requests to loopback, internal, and cloud-metadata IPv4 literals, but the deny rule only matched dotted-decimal notation, so alternate IPv4 encodings of the same addresses, including...

CVE-2026-58404 Hugo security.http.urls deny rules bypassed by alternate IPv4 encodings

CVE-2026-58404

Hugo: From v0.162.0 to v0.163.0, the default security.http.urls policy blocked loopback/internal/cloud-metadata IPv4 literals, but the deny rule only matched dotted-decimal notation. Consequently, alternate IPv4 encodings (integer, hex, octal) could resolve to blocked addresses when a template pa...

nats-server: NATS Server: Information disclosure via MQTT client subscription bypass

A flaw was found in NATS Server, a high-performance messaging system. An authenticated MQTT Message Queuing Telemetry Transport client could bypass security permissions by subscribing to an internal subject family. This unauthorized access allows the client to view sensitive MQTT Quality of Servi...

nodejs: Node.js: Unauthorized file metadata modification

A flaw was found in Node.js. The Permission API allows a local user to modify file metadata on paths that have been explicitly set as read-only. This can lead to unauthorized changes in file properties, impacting the integrity of the file system...

rabbitmq: RabbitMQ: Authorization bypass allows unauthorized topic writes and binds during metadata-store failures

A flaw was found in RabbitMQ, a messaging and streaming broker. During metadata-store failures, the topic authorization mechanism can incorrectly allow restricted topic writes and binds. This occurs because permission lookup errors from Khepri are treated as an 'allow' condition by the internal...
