Node.js Module axios < 0.32.0 / 1.x < 1.16.0 NO_PROXY Bypass (SSRF)

The version of the axios Node.js module installed on the remote host is prior to 0.32.0 or 1.x prior to 1.16.0. It is, therefore, affected by the following vulnerability: - shouldBypassProxy, introduced in v1.15.0 to fix CVE-2025-62718, does not normalise IPv4-mapped IPv6 addresses. When NOPROXY...

USN-8391-1: Linux kernel (Raspberry Pi) vulnerabilities

It was discovered that the Linux kernel algifaead module did not properly handle in-place cryptographic operations. This flaw is known as Copy Fail. A local attacker could use this to escalate privileges, or possibly escape a container. CVE-2026-31431 It was discovered that the Linux kernel did n...

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...

CVE-2026-48682

A flaw was found in FastNetMon Community Edition. This vulnerability, located in the IPv4 packet parser, allows a remote attacker to send specially crafted network packets. This can lead to an out-of-bounds read, potentially disclosing sensitive information or causing the system to crash, resulti...

curl: curl/libcurl 8.20.0 NOPROXY bypass via uppercase-hex IPv4 aliases leaks off-proxy Basic credentials to the configured proxy

Summary: curl/libcurl 8.20.0 fails to enforce CURLOPTNOPROXY, --noproxy, and NOPROXY consistently for uppercase-hex IPv4 aliases such as 0X7f.1 on glibc-based systems that accept these legacy numeric IPv4 forms. When a canonical IP literal is excluded from proxying, curl sends the canonical form...

CVE-2026-10124

A vulnerability was determined in Shibby Tomato up to 1.28. Affected is the function ripzebrareadipv4 of the file /usr/sbin/ripd of the component Zserv Handler. Executing a manipulation can lead to stack-based buffer overflow. It is possible to launch the attack remotely. The exploit has been...
