Mattermost fails to canonicalize IPv4-mapped IPv6 addresses before reserved IP validation
Mattermost versions 11.3.x = 11.3.0, 11.2.x = 11.2.2, 10.11.x = 10.11.10 fail to canonicalize IPv4-mapped IPv6 addresses before reserved IP validation which allows an attacker to perform SSRF attacks against internal services via IPv4-mapped IPv6 literals e.g., ::ffff:127.0.0.1.. Mattermost...
USN-8098-1: Linux kernel vulnerabilities
Qualys discovered that several vulnerabilities existed in the AppArmor Linux kernel Security Module LSM. An unprivileged local attacker could use these issues to load, replace, and remove arbitrary AppArmor profiles causing denial of service, exposure of sensitive information kernel memory, local...

CVE-2026-22201
wpDiscuz before 7.6.47 is affected by an IP spoofing vulnerability in the getIP() function. By trusting untrusted HTTP headers (HTTP_CLIENT_IP or HTTP_X_FORWARDED_FOR), an attacker can spoof their IP address and bypass IP-based rate limiting and ban enforcement. The CVE entry specifies the issue ...
[SECURITY] Fedora 42 Update: perl-Net-CIDR-0.27-1.fc42
The Net::CIDR package contains functions that manipulate lists of IP netblocks expressed in CIDR notation. The Net::CIDR functions handle both IPv4 and IPv6 addresses...
The vulnerability of the `tcp_ao_finish_connect()` function in the `net/ipv4/tcp_ao.c` module of the Linux operating system’s IPv4 protocol implementation allows a attacker to cause a service failure.
The vulnerability of the tcpaofinishconnect function in the net/ipv4/tcpao.c module of the Linux operating system’s IPv4 protocol implementation is related to the pointer dereferencing. Exploiting this vulnerability could allow a remote attacker to cause service interruptions...

CVE-2026-30827
CVE-2026-30827 affects express-rate-limit for Express. The default keyGenerator mishandles IPv4 when the system treats IPv4 addresses as IPv6 mapped (IPv4-mapped IPv6 addresses like ::ffff:x.x.x.x). On dual-stack servers, this causes a /56 subnet mask to be applied to all IPv6 addresses, making a...
CVE-2026-30827 express-rate-limit: IPv4-mapped IPv6 addresses bypass per-client rate limiting (all IPv4 clients share one bucket on dual-stack servers)
express-rate-limit is a basic rate-limiting middleware for Express. In versions starting from 8.0.0 and prior to versions 8.0.2, 8.1.1, 8.2.2, and 8.3.0, the default keyGenerator in express-rate-limit applies IPv6 subnet masking /56 by default to all addresses that net.isIPv6 returns true for. Th...

express-rate-limit: IPv4-mapped IPv6 addresses bypass per-client rate limiting on servers with dual-stack network
Summary The default keyGenerator in express-rate-limit applies IPv6 subnet masking /56 by default to all addresses that net.isIPv6 returns true for. This includes IPv4-mapped IPv6 addresses ::ffff:x.x.x.x, which Node.js returns as request.ip on dual-stack servers. Because the first 80 bits of all...
