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...

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...

CVE-2026-48772

ProxySQL is a proxy for MySQL and its forks, as well as PostgreSQL. In versions 2.0.0 through 3.0.8, the ProxySQL MySQL frontend accepts the PROXY UNKNOWN \r\n PP1 frame as a well-formed PROXY protocol header. The HAProxy PROXY protocol v1 specification says that when the protocol token is UNKNOW...

GHSA-64MM-VXMG-Q3VJ http-proxy-middleware `router` host+path substring matching allows Host-header-driven backend routing bypass

Summary 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 metadata. As a result, a crafted Host header that is only a superstring match for a configur...

PT-2026-51015

Name of the Vulnerable Software and Affected Versions ProxySQL versions 2.0.0 through 3.0.8 Description The MySQL frontend incorrectly processes the PROXY UNKNOWN r PP1 frame of the PROXY protocol v1. According to the specification, when the protocol token is UNKNOWN, the receiver must ignore...

Improper Access Control

Caddy is vulnerable to Improper Access Control. The vulnerability is due to incorrect case-insensitive matching in the HTTP path request matcher when percent-encoded sequences are present, allowing attackers to alter request path casing and bypass path-based routing or attached access controls...

Improper Access Control

Caddy is vulnerable to Improper Access Control. The vulnerability is due to incorrect case-insensitive matching in the HTTP host request matcher when large host lists are configured, allowing attackers to modify the casing of the Host header and bypass host-based routing or associated access...

CVE-2026-40910

frp is a fast reverse proxy. From 0.43.0 to 0.68.0, frp contains an authentication bypass in the HTTP vhost routing path when routeByHTTPUser is used as part of access control. In proxy-style requests, the routing logic uses the username from Proxy-Authorization to select the routeByHTTPUser...

LobeHub 安全漏洞

Caddy: MatchHost becomes case-sensitive for large host lists (>100), enabling host-based route/auth bypass

Summary Caddy's HTTP host request matcher is documented as case-insensitive, but when configured with a large host list 100 entries it becomes case-sensitive due to an optimized matching path. An attacker can bypass host-based routing and any access controls attached to that route by changing the...
