CVE-2024-52530

HIGH

GNOME libsoup < 3.6.0 - HTTP Request Smuggling via Null Byte in Header Names

Title source: llm

Description

GNOME libsoup before 3.6.0 allows HTTP request smuggling in some configurations because '\0' characters at the end of header names are ignored, i.e., a "Transfer-Encoding\0: chunked" header is treated the same as a "Transfer-Encoding: chunked" header.
