CVE-2026-75922

Reverse::Proxy versions before 0.04 for Perl allow HTTP request smuggling via a percent-decoded PATHINFO written unencoded to the upstream request line. PSGI hands PATHINFO to an application percent-decoded, so a %XX sequence in the client URL has become a raw byte by the time the proxy sees it...

CVE-2026-75922

The Reverse::Proxy Perl module, in versions before 0.04 , is vulnerable to HTTP request smuggling . The issue occurs because PSGI provides a percent-decoded PATH_INFO to the application; a %XX sequence in the client URL becomes a raw byte which the proxy then appends unencoded to the upstream req...

CVE-2026-34786: Incorrect Behavior Order: Validate Before Canonicalize

Rack is a modular Ruby web server interface. Prior to versions 2.2.23, 3.1.21, and 3.2.6, Rack::Staticapplicablerules evaluates several headerrules types against the raw URL-encoded PATHINFO, while the underlying file-serving path is decoded before the file is served. As a result, a request for a...
