CVE-2026-10725 Protocol::HTTP2 versions through 1.12 for Perl is vulnerable to a HTTP/2 Bomb

Protocol::HTTP2 versions through 1.12 for Perl is vulnerable to a HTTP/2 Bomb. Protocol::HTTP2's inbound HPACK path has no header-list size limit, so a small HTTP/2 request can expand into large server memory the "HTTP/2 bomb". The headersdecode method materialises a full key+value copy per index...

Golang 1.25.x < 1.25.11 / 1.26.x < 1.26.4 Multiple Vulnerabilities

The version of Golang running on the remote host is 1.25.x prior to 1.25.11, or 1.26.x prior to 1.26.4. It is, therefore, affected by multiple vulnerabilities: - x509.Certificate.VerifyHostname previously called matchHostnames in a loop over all DNS Subject Alternative Name SAN entries. This caus...

quic-go: HTTP/3 QPACK Trailer Expansion Memory Exhaustion

Summary An attacker can cause excessive memory allocation in quic-go's HTTP/3 client and server implementations by sending a QPACK-encoded HEADERS frame that decodes into a large trailer field section with many unique field names and/or large values. The implementation builds an http.Header for t...

DEBIAN-CVE-2026-45372

cpp-httplib is a C++11 single-file header-only cross platform HTTP/HTTPS library. Prior to 0.44.0, when cpp-httplib's server parses an incoming request, it applies percent-decoding to every header value except Location and Referer. The validity check isfieldvalue is run before decoding, so encode...

CVE-2026-45372

In cpp-httplib, prior to version 0.44.0, the server-side header parsing in parse_header applies percent-decoding to header values (except Location and Referer) after validating the pre-decoded string. The validity check (is_field_value) runs before decoding, allowing an encoded %0D%0A to bypass c...
