Vulnerability from github – Published: 2026-03-17 12:30 – Updated: 2026-03-17 12:30

Details

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.

Severity ?

3.9 (Low)


                  
                    CVSS:3.1/AV:N/AC:H/PR:H/UI:R/S:U/C:L/I:L/A:L

Vulnerability from cvelistv5 – Published: 2026-03-17 09:44 – Updated: 2026-03-19 20:55

Title

Libsoup: libsoup: http header injection and response splitting via crlf injection in content-type header

Summary

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.

Severity ?

3.9 (Low)
