CVE-2026-18664: Improper Access Control

When ranges are used for access control i.e. of the form 1.2.3.4-1.2.3.25, because NSD wrongly compares the IP address with the range on little endian systems, IPs that were meant to be allowed may be denied, and, IPs that were meant to be denied access could be allowed. An IPv4 address is compar...

CVE-2026-80350: Server-Side Request Forgery (SSRF)

OneUptime's webhook target check rejects private and loopback addresses given in IPv4 form and a small set of IPv6 forms, but has no case for the IPv4-mapped IPv6 range. The webhook delivery path calls SSRFProtection.validateWebhookTargetIsSafe, and the host-literal screening inside...

CVE-2026-52776

compliance-trestle (Trestle), a Python tooling platform for managing compliance-as-code via OSCAL, contains an SSRF bypass in its URLSecurityValidator (trestle/core/remote/security.py). The validator fails to canonicalize IPv4-mapped IPv6 literals (e.g., [::ffff:169.254.169.254]) before network m...

The vulnerability of the `tcp_bpf_send_verdict()` function in the `net/ipv4/tcp_bpf.c` module, which is part of the IPv4 protocol implementation in Linux kernel, allows a attacker to cause a service failure.

The vulnerability of the tcpbpfsendverdict function in the net/ipv4/tcpbpf.c module of the Linux operating system’s IPv4 protocol implementation leads to uncontrolled resource consumption. Exploiting this vulnerability could allow an attacker to cause a service failure...

ROS-20260825-73-0009

The vulnerability of the tcpdisconnect function in the net/ipv4/tcp.c module of the Linux operating system’s IPv4 protocol implementation is related to improper release of resources. Exploiting this vulnerability could allow an attacker to compromise the confidentiality, integrity, and...

The vulnerability of the esp_output_done() function in the net/ipv4/esp4.c module of the IPv4 protocol implementation in the Linux operating system allows a attacker to cause a service failure.

The vulnerability of the espoutputdone function in the net/ipv4/esp4.c module of the IPv4 protocol implementation in the Linux operating system is related to incomplete cleanup of temporary or auxiliary resources. Exploiting this vulnerability can allow an attacker to cause a service failure...

CVE-2026-74656

A flaw was found in the Linux kernel's IPv4 networking stack. A use-after-free vulnerability exists in the fibnhcupdatemtu function due to a race condition during nexthop exception table updates. This allows for a scenario where memory can be freed while still being accessed, which can lead to a...

ip-address: ip-address: Server-Side Request Forgery via IPv4-mapped/NAT64 IPv6 address misclassification

A flaw was found in the ip-address library. This library, used for parsing and manipulating IPv4 and IPv6 addresses in JavaScript, is vulnerable to Server-Side Request Forgery SSRF due to incorrect classification of IPv4-mapped/NAT64 IPv6 addresses. An attacker could exploit this misclassificatio...
