CVE-2026-55602 http-proxy-middleware `router` host+path substring matching allows Host-header-driven backend routing bypass

http-proxy-middleware is node.js http-proxy middleware. From 0.16.0 until 2.0.10, 3.0.6, and 4.1.0, http-proxy-middleware documents router proxy-table entries as host, path, or host+path selectors, but the host+path implementation uses unanchored substring matching on attacker-controlled request...

CVE-2026-55602

The CVE-2026-55602 issue affects http-proxy-middleware (Node.js) versions 0.16.0 through 2.0.10, 3.0.6, and 4.1.0. The host+path router uses unanchored substring matching on attacker-controlled request metadata, enabling a crafted Host header that is a superstring match for a configured key to ro...

USN-8459-1: HAProxy vulnerabilities

It was discovered that HAProxy incorrectly handled the FCGI demultiplexer record length field. A remote attacker could possibly use this issue to cause incorrect request routing, response smuggling, or other memory safety issues. CVE-2026-55203 It was discovered that HAProxy failed to validate th...

CVE-2026-48772

A flaw was found in ProxySQL, a proxy for MySQL and its forks, as well as PostgreSQL. A remote attacker can exploit this vulnerability by sending a specially crafted PROXY protocol version 1 PP1 header with an 'UNKNOWN' protocol token. Despite the specification requiring these address fields to b...

kernel: ipv6: rpl: reserve mac_len headroom when recompressed SRH grows

A flaw was found in the Linux kernel. A local attacker can exploit an out-of-bounds write vulnerability when the kernel recomputes an IPv6 Source Routing Header SRH. This issue occurs because insufficient headroom is reserved during the recompression process, leading to memory corruption...

Improper Request Routing

http-proxy-middleware is vulnerable to improper request routing. The vulnerability is due to unanchored substring matching in the host+path router selector logic, where configured host+path entries are matched against attacker-controlled request metadata using partial string comparisons instead o...

SUSE CVE-2026-55203

HAProxy through 3.4.0, fixed in commit 5985276, contains an integer overflow vulnerability in the fcgiconn structure's drl field that allows buffer misparse as new FCGI record headers. When contentLength is 65535 and paddingLength is 1 or more, the drl field wraps to 0, causing incorrect record...
