Title
Libsoup: libsoup: duplicate host header handling causes host-parsing discrepancy (first- vs last-value wins)
Summary
A flaw in libsoup’s HTTP header handling allows multiple Host: headers in a request and returns the last occurrence for server-side processing. Common front proxies often honor the first Host: header, so this mismatch can cause vhost confusion where a proxy routes a request to one backend but the backend interprets it as destined for another host. This discrepancy enables request-smuggling style attacks, cache poisoning, or bypassing host-based access controls when an attacker supplies duplicate Host headers.
Severity ?
8.2 (High)
CWE
- CWE-444 - Inconsistent Interpretation of HTTP Requests ('HTTP Request/Response Smuggling')

Summary
A flaw in libsoup’s HTTP header handling allows multiple Host: headers in a request and returns the last occurrence for server-side processing. Common front proxies often honor the first Host: header, so this mismatch can cause vhost confusion where a proxy routes a request to one backend but the backend interprets it as destined for another host. This discrepancy enables request-smuggling style attacks, cache poisoning, or bypassing host-based access controls when an attacker supplies duplicate Host headers.

Common front proxies often honor the first Host: header, so this mismatch can cause vhost confusion where a proxy routes a request to one backend but the backend interprets it as destined for another host. This discrepancy enables request-smuggling style attacks, cache poisoning, or bypassing host-based access controls when an attacker supplies duplicate Host headers.",

"text": "This vulnerability is rated Important for Red Hat products that utilize libsoup in environments where applications are exposed via a front proxy. The flaw arises from a discrepancy in how libsoup processes duplicate Host: headers (last-value wins) compared to many proxies (first-value wins). This mismatch can lead to virtual-host confusion, enabling attackers to bypass host-based access controls or perform cache poisoning. Systems where libsoup applications are directly accessible without an intervening proxy are not affected by this specific issue.",

Systems where libsoup applications are directly accessible without an intervening proxy are not affected by this specific issue.",

Common front proxies often honor the first Host: header, so this mismatch can cause vhost confusion where a proxy routes a request to one backend but the backend interprets it as destined for another host. This discrepancy enables request-smuggling style attacks, cache poisoning, or bypassing host-based access controls when an attacker supplies duplicate Host headers.",

"text": "This vulnerability is rated Important for Red Hat products that utilize libsoup in environments where applications are exposed via a front proxy. The flaw arises from a discrepancy in how libsoup processes duplicate Host: headers (last-value wins) compared to many proxies (first-value wins). This mismatch can lead to virtual-host confusion, enabling attackers to bypass host-based access controls or perform cache poisoning. Systems where libsoup applications are directly accessible without an intervening proxy are not affected by this specific issue.",

"text": "A flaw in libsoup\u2019s HTTP header handling allows multiple Host: headers in a request and returns the last occurrence for server-side processing. Common front proxies often honor the first Host: header, so this mismatch can cause vhost confusion where a proxy routes a request to one backend but the backend interprets it as destined for another host. This discrepancy enables request-smuggling style attacks, cache poisoning, or bypassing host-based access controls when an attacker supplies duplicate Host headers.",

"text": "This vulnerability is rated Important for Red Hat products that utilize libsoup in environments where applications are exposed via a front proxy. The flaw arises from a discrepancy in how libsoup processes duplicate Host: headers (last-value wins) compared to many proxies (first-value wins). This mismatch can lead to virtual-host confusion, enabling attackers to bypass host-based access controls or perform cache poisoning. Systems where libsoup applications are directly accessible without an intervening proxy are not affected by this specific issue.",

The flaw arises from a discrepancy in how libsoup processes duplicate Host: headers (last-value wins) compared to many proxies (first-value wins).

Systems where libsoup applications are directly accessible without an intervening proxy are not affected by this specific issue.",

Vulnerability from csaf_redhat - Published: 2026-01-20 06:18 - Updated: 2026-01-21 15:54Summary
Red Hat Security Advisory: libsoup3 security update
Notes
Topic
An update for libsoup3 is now available for Red Hat Enterprise Linux 10.0 Extended Update Support.
Red Hat Product Security has rated this update as having a security impact of Important. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section.
Details
Libsoup is an HTTP library implementation in C. It was originally part of a SOAP (Simple Object Access Protocol) implementation called Soup, but the SOAP and non-SOAP parts have now been split into separate packages. libsoup uses the Glib main loop and is designed to work well with GTK applications. This enables GNOME applications to access HTTP servers on the network in a completely asynchronous fashion, very similar to the Gtk+ programming model (a synchronous operation mode is also supported for those who want it), but the SOAP parts were removed long ago.
Security Fix(es):
* libsoup: libsoup: Duplicate Host Header Handling Causes Host-Parsing Discrepancy (First- vs Last-Value Wins) (CVE-2025-14523)
For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page(s) listed in the References section.

"text": "A flaw in libsoup\u2019s HTTP header handling allows multiple Host: headers in a request and returns the last occurrence for server-side processing. Common front proxies often honor the first Host: header, so this mismatch can cause vhost confusion where a proxy routes a request to one backend but the backend interprets it as destined for another host. This discrepancy enables request-smuggling style attacks, cache poisoning, or bypassing host-based access controls when an attacker supplies duplicate Host headers.",

"category": "other",
"text": "This vulnerability is rated Important for Red Hat products that utilize libsoup in environments where applications are exposed via a front proxy. The flaw arises from a discrepancy in how libsoup processes duplicate Host: headers (last-value wins) compared to many proxies (first-value wins). This mismatch can lead to virtual-host confusion, enabling attackers to bypass host-based access controls or perform cache poisoning. Systems where libsoup applications are directly accessible without an intervening proxy are not affected by this specific issue.",

"text": "This vulnerability is rated Important for Red Hat products that utilize libsoup in environments where applications are exposed via a front proxy. The flaw arises from a discrepancy in how libsoup processes duplicate Host: headers (last-value wins) compared to many proxies (first-value wins). This mismatch can lead to virtual-host confusion, enabling attackers to bypass host-based access controls or perform cache poisoning. Systems where libsoup applications are directly accessible without an intervening proxy are not affected by this specific issue.",

"text": "This vulnerability is rated Important for Red Hat products that utilize libsoup in environments where applications are exposed via a front proxy. The flaw arises from a discrepancy in how libsoup processes duplicate Host: headers (last-value wins) compared to many proxies (first-value wins). This mismatch can lead to virtual-host confusion, enabling attackers to bypass host-based access controls or perform cache poisoning. Systems where libsoup applications are directly accessible without an intervening proxy are not affected by this specific issue.",

Vulnerability from csaf_redhat - Published: 2026-01-12 01:38 - Updated: 2026-01-21 15:54Summary
Red Hat Security Advisory: libsoup3 security update
Notes
Topic
An update for libsoup3 is now available for Red Hat Enterprise Linux 10.
Red Hat Product Security has rated this update as having a security impact of Important. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section.
Details
Libsoup is an HTTP library implementation in C. It was originally part of a SOAP (Simple Object Access Protocol) implementation called Soup, but the SOAP and non-SOAP parts have now been split into separate packages. libsoup uses the Glib main loop and is designed to work well with GTK applications. This enables GNOME applications to access HTTP servers on the network in a completely asynchronous fashion, very similar to the Gtk+ programming model (a synchronous operation mode is also supported for those who want it), but the SOAP parts were removed long ago.
Security Fix(es):
* libsoup: libsoup: Duplicate Host Header Handling Causes Host-Parsing Discrepancy (First- vs Last-Value Wins) (CVE-2025-14523)
For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page(s) listed in the References section.

"text": "A flaw in libsoup\u2019s HTTP header handling allows multiple Host: headers in a request and returns the last occurrence for server-side processing. Common front proxies often honor the first Host: header, so this mismatch can cause vhost confusion where a proxy routes a request to one backend but the backend interprets it as destined for another host. This discrepancy enables request-smuggling style attacks, cache poisoning, or bypassing host-based access controls when an attacker supplies duplicate Host headers.",

"text": "This vulnerability is rated Important for Red Hat products that utilize libsoup in environments where applications are exposed via a front proxy. The flaw arises from a discrepancy in how libsoup processes duplicate Host: headers (last-value wins) compared to many proxies (first-value wins). This mismatch can lead to virtual-host confusion, enabling attackers to bypass host-based access controls or perform cache poisoning. Systems where libsoup applications are directly accessible without an intervening proxy are not affected by this specific issue.",

Common front proxies often honor the first Host: header, so this mismatch can cause vhost confusion where a proxy routes a request to one backend but the backend interprets it as destined for another host. This discrepancy enables request-smuggling style attacks, cache poisoning, or bypassing host-based access controls when an attacker supplies duplicate Host headers.",

"text": "This vulnerability is rated Important for Red Hat products that utilize libsoup in environments where applications are exposed via a front proxy. The flaw arises from a discrepancy in how libsoup processes duplicate Host: headers (last-value wins) compared to many proxies (first-value wins). This mismatch can lead to virtual-host confusion, enabling attackers to bypass host-based access controls or perform cache poisoning. Systems where libsoup applications are directly accessible without an intervening proxy are not affected by this specific issue.",

The flaw arises from a discrepancy in how libsoup processes duplicate Host: headers (last-value wins) compared to many proxies (first-value wins).

Systems where libsoup applications are directly accessible without an intervening proxy are not affected by this specific issue.",

Common front proxies often honor the first Host: header, so this mismatch can cause vhost confusion where a proxy routes a request to one backend but the backend interprets it as destined for another host. This discrepancy enables request-smuggling style attacks, cache poisoning, or bypassing host-based access controls when an attacker supplies duplicate Host headers.",

"text": "This vulnerability is rated Important for Red Hat products that utilize libsoup in environments where applications are exposed via a front proxy. The flaw arises from a discrepancy in how libsoup processes duplicate Host: headers (last-value wins) compared to many proxies (first-value wins). This mismatch can lead to virtual-host confusion, enabling attackers to bypass host-based access controls or perform cache poisoning. Systems where libsoup applications are directly accessible without an intervening proxy are not affected by this specific issue.",

{
"category": "general",
"text": "A flaw in libsoup\u0027s HTTP header handling allows multiple Host: headers in a request and returns the last occurrence for server-side processing. Common front proxies often honor the first Host: header, so this mismatch can cause vhost confusion where a proxy routes a request to one backend but the backend interprets it as destined for another host. This discrepancy enables request-smuggling style attacks, cache poisoning, or bypassing host-based access controls when an attacker supplies duplicate Host headers.",

GHSA-4QPP-GXM3-H9VW
Vulnerability from github – Published: 2025-12-11 15:30 – Updated: 2026-01-21 18:30
VLAI?
Details
A flaw in libsoup’s HTTP header handling allows multiple Host: headers in a request and returns the last occurrence for server-side processing. Common front proxies often honor the first Host: header, so this mismatch can cause vhost confusion where a proxy routes a request to one backend but the backend interprets it as destined for another host. This discrepancy enables request-smuggling style attacks, cache poisoning, or bypassing host-based access controls when an attacker supplies duplicate Host headers.
Severity ?
8.2 (High)
