CVE-2026-53131

In CVE-2026-53131, multiple netfilter-related paths in the Linux kernel (including ip6t_eui64, xt_mac, and several ipset types) could access Ethernet MAC header data via eth_hdr(skb) without first verifying that the skb is associated with an Ethernet device or that the MAC header is present and l...

curl: CURLOPT_HAPROXY_CLIENT_IP lacks input validation, enabling HAProxy PROXY protocol injection

Summary The CURLOPTHAPROXYCLIENTIP option accepts an arbitrary string without validating that it is a valid IP address, and without stripping special characters such as \r\n CRLF or spaces. Because this value is embedded directly into the HAProxy PROXY protocol v1 header line, an attacker who can...

CVE-2026-55602

A flaw was found in http-proxy-middleware before 2.0.10, 3.0.6, and 4.1.0. Router proxy-table host+path matching uses unanchored substring comparison on the Host header, so a crafted Host value that superstring-matches a configured key can route requests to an unintended backend...

In the Linux kernel, the following vulnerability has been resolved: tun: zero the whole vnet header in tunputuser tunputuser declares an on-stack struct virtionethdrv1hashtunnel without zeroing it. For a non-tunnel skb, virtionethdrtnlfromskb only initializes the first 10 bytes sizeofstruct...

SUSE CVE-2026-52942

In the Linux kernel, the following vulnerability has been resolved: netfilter: nflog: validate MAC header was set before dumping it The fallback path of dumpmacheader guards the MAC header access only with "skb-macheader != skb-networkheader", without checking skbmacheaderwasset. When the MAC...

CVE-2026-28898: Improper Encoding or Escaping of Output

swift-nio-http2's HTTP/2-to-HTTP/1.1 codec did not validate pseudo-header values for control characters before placing them into the translated HTTP/1.1 message. swift-nio-http2 1.44.1 adds validation of all pseudo-header values :path, :authority, :scheme, :method, and :status at both the HPACK...

CVE-2026-50017: Exposure of Sensitive Information to an Unauthorized Actor

pnpm is a package manager. Prior to 10.34.0 and 11.4.0, pnpm can send user-level unscoped npm authentication credentials to a registry chosen by a repository-local .npmrc file. In the reproduced case, the user's npm config contains a default registry and an unscoped authToken. The repository does...

Summary realip middleware in go-chi/chi trusts headers like x-forwarded-for without checking them, so attackers can fake their ip and bypass rate limits or access controls Details the vuln is in middleware/realip.go , the realIP function pulls IPs straight from client headers and replaces...

PT-2026-55841

Summary The RealIP middleware in go-chi/chi is vulnerable to IP spoofing because it blindly trusts the first leftmost element of the X-Forwarded-For HTTP header. This allows a remote attacker to bypass IP-based access control lists ACLs and rate-limiting mechanisms by providing a spoofed IP addre...
