CVE-2026-40562 (GCVE-0-2026-40562)
Vulnerability from cvelistv5 – Published: 2026-05-06 12:36 – Updated: 2026-05-07 16:13

Title
Gazelle versions through 0.49 for Perl allows HTTP Request Smuggling via Improper Header Precedence
Summary
Gazelle versions through 0.49 for Perl allows HTTP Request Smuggling via Improper Header Precedence.
Gazelle incorrectly prioritizes "Content-Length" over "Transfer-Encoding: chunked" when both headers are present in an HTTP request. Per RFC 7230 3.3.3, Transfer-Encoding must take precedence.
An attacker could exploit this to smuggle malicious HTTP requests via a front-end reverse proxy.

CVE-2025-40926 (GCVE-0-2025-40926)
Vulnerability from cvelistv5 – Published: 2026-03-05 01:24 – Updated: 2026-04-21 02:42

Title
Plack::Middleware::Session::Simple versions before 0.05 for Perl generates session ids insecurely
Summary
Plack::Middleware::Session::Simple versions before 0.05 for Perl generates session ids insecurely.
The default session id generator returns a SHA-1 hash seeded with the built-in rand function, the epoch time, and the PID. The PID will come from a small set of numbers, and the epoch time may be guessed, if it is not leaked from the HTTP Date header. The built-in rand function is unsuitable for cryptographic usage.
Predictable session ids could allow an attacker to gain access to systems.
Plack::Middleware::Session::Simple is intended to be compatible with Plack::Middleware::Session, which had a similar security issue CVE-2025-40923.
