Axios is a promise based HTTP client for the browser and Node.js. Prior to 0.32.0 and 1.16.0, Axios does not normalise IPv4-mapped IPv6 addresses. When NOPROXY lists an IPv4 address such as 127.0.0.1 or 169.254.169.254, a request URL using the IPv4-mapped IPv6 form ::ffff:7f00:1, ::ffff:a9fe:a9fe...

Ubuntu 20.04 LTS : Linux kernel (FIPS) vulnerabilities (USN-7461-2)

The remote Ubuntu 20.04 LTS host has a package installed that is affected by multiple vulnerabilities as referenced in the USN-7461-2 advisory. Several security issues were discovered in the Linux kernel. An attacker could possibly use these to compromise the system. This update corrects flaws in...

Axios 代码问题漏洞

Axios is an open-source HTTP client developed by Axios, based on Promise a solution for asynchronous programming. There were code-related vulnerabilities in versions of Axios before 0.32.0 and 1.16.0. These vulnerabilities stemmed from unnormalized IPv4-to-Ipv6 address mappings, which could lead ...

EUVD-2026-36113

Weblate is a web based localization tool. From version 5.15 to before version 2026.6, Weblate's VCSRESTRICTPRIVATE did not properly account for some transitional IPv6 ranges, multicast addresses, or some semi-private IPv4 ranges, which allowed some addresses to bypass private range restrictions...

kernel: netfilter: ip6t_eui64: reject invalid MAC header for all packets

A flaw was found in the Linux kernel's netfilter component. This vulnerability occurs because the eui64mt6 function, which processes IPv6 packets, does not properly validate the MAC header for all packets. Specifically, packets with a zero fragment offset could bypass an existing guard, allowing...

CVE-2026-49494

Comodo Internet Security's firewall driver Inspect.sys contains an integer underflow in its IPv6 packet parser. The parser decrements an unsigned 64-bit payload-length value taken from the IPv6 fixed header's payload length field by the size of each IPv6 extension header without validating it, so...

CVE-2026-49494 Comodo Internet Security Inspect.sys IPv6 Integer Underflow Remote Denial of Service

Comodo Internet Security's firewall driver Inspect.sys contains an integer underflow in its IPv6 packet parser. The parser decrements an unsigned 64-bit payload-length value taken from the IPv6 fixed header's payload length field by the size of each IPv6 extension header without validating it, so...

CVE-2026-8369

Improper Input Validation in the NAT64 translator in The OpenThread Authors OpenThread before commit 26a882d on all platforms allows an attacker on the adjacent IPv4 network to inject corrupted IPv6 packets into the Thread mesh or bypass security checks via crafted IPv4 packets with options...

kernel: ip6_tunnel: clear skb2->cb[] in ip4ip6_err()

A flaw was found in the Linux kernel's IPv6 tunnel implementation. A remote attacker could exploit this flaw by sending malicious ICMPv6 error messages to cause a stack-based buffer overflow in the kernel's IPv4-over-IPv6 tunnel error handling code. This could result in a kernel crash denial of...

kernel: netfilter: ip6t_eui64: reject invalid MAC header for all packets

A flaw was found in the Linux kernel's netfilter component. This vulnerability occurs because the eui64mt6 function, which processes IPv6 packets, does not properly validate the MAC header for all packets. Specifically, packets with a zero fragment offset could bypass an existing guard, allowing...

kernel: ipv6: use RCU in ip6_xmit()
