rabbitmq: RabbitMQ: Authentication bypass allows remote connection for loopback-restricted users via incorrect loopback check

A flaw was found in RabbitMQ, a messaging and streaming broker. The AMQP 0-9-1, AMQP 1.0, and Stream Protocol authentication mechanisms incorrectly perform a loopback check. This allows a user, typically restricted to loopback connections such as a guest user, to connect remotely. This occurs whe...

kernel: ALSA: aloop: Fix peer runtime UAF during format-change stop

A flaw was found in the Linux kernel's ALSA Advanced Linux Sound Architecture aloop driver. This Use-After-Free UAF vulnerability occurs when loopbackcheckformat stops the capture side during a format change, while a concurrent close operation detaches or frees the runtime. An attacker could...

BIT-MASTODON-2026-46348 Mastodon: SSRF Bypass via IPv6 Unspecified Address (::)

Mastodon is a free, open-source social network server based on ActivityPub. Prior to 4.5.10, 4.4.17, and 4.3.23, the list of disallowed IP address ranges was lacking an IP address range that can be used to reach local IP addresses. An attacker can use an IP address in the affected range to make...
