Vulnerability Title
Libsoup: libsoup: http header injection and response splitting via crlf injection in content-type header
Source: NVD (National Vulnerability Database)
Vulnerability Description
A flaw was found in libsoup. An attacker controlling the value used to set the Content-Type header can inject a Carriage Return Line Feed (CRLF) sequence due to improper input sanitization in the `soup_message_headers_set_content_type()` function. This vulnerability allows for the injection of arbitrary header-value pairs, potentially leading to HTTP header injection and response splitting attacks.
