| CVE-2026-2443 | 2 Gnome, Redhat | 2 Libsoup, Enterprise Linux | 2026-06-17 | N/A | 5.3 MEDIUM |
| A flaw was identified in libsoup, a widely used HTTP library in GNOME-based systems. When processing specially crafted HTTP Range headers, the library may improperly validate requested byte ranges. In certain build configurations, this could allow a remote attacker to access portions of server memory beyond the intended response. Exploitation requires a vulnerable configuration and access to a server using the embedded SoupServer component. | |||||
| CVE-2026-1801 | 2 Gnome, Redhat | 2 Libsoup, Enterprise Linux | 2026-06-17 | N/A | 5.3 MEDIUM |
| A flaw was found in libsoup, an HTTP client/server library. This HTTP Request Smuggling vulnerability arises from non-RFC-compliant parsing in the soup_filter_input_stream_read_line() logic, where libsoup accepts malformed chunk headers, such as lone line feed (LF) characters instead of the required carriage return and line feed (CRLF). A remote attacker can exploit this without authentication or user interaction by sending specially crafted chunked requests. This allows libsoup to parse and process multiple HTTP requests from a single network message, potentially leading to information disclosure. | |||||
| CVE-2026-1539 | 2 Gnome, Redhat | 2 Libsoup, Enterprise Linux | 2026-06-17 | N/A | 5.8 MEDIUM |
| A flaw was found in the libsoup HTTP library that can cause proxy authentication credentials to be sent to unintended destinations. When handling HTTP redirects, libsoup removes the Authorization header but does not remove the Proxy-Authorization header if the request is redirected to a different host. As a result, sensitive proxy credentials may be leaked to third-party servers. Applications using libsoup for HTTP communication may unintentionally expose proxy authentication data. | |||||
| CVE-2026-1536 | 2 Gnome, Redhat | 2 Libsoup, Enterprise Linux | 2026-06-17 | N/A | 5.8 MEDIUM |
| A flaw was found in libsoup. An attacker who can control the input for the Content-Disposition header can inject CRLF (Carriage Return Line Feed) sequences into the header value. These sequences are then interpreted verbatim when the HTTP request or response is constructed, allowing arbitrary HTTP headers to be injected. This vulnerability can lead to HTTP header injection or HTTP response splitting without requiring authentication or user interaction. | |||||
| CVE-2026-1467 | 2 Gnome, Redhat | 2 Libsoup, Enterprise Linux | 2026-06-17 | N/A | 5.8 MEDIUM |
| A flaw was found in libsoup, an HTTP client library. This vulnerability, known as CRLF (Carriage Return Line Feed) Injection, occurs when an HTTP proxy is configured and the library improperly handles URL-decoded input used to create the Host header. A remote attacker can exploit this by providing a specially crafted URL containing CRLF sequences, allowing them to inject additional HTTP headers or complete HTTP request bodies. This can lead to unintended or unauthorized HTTP requests being forwarded by the proxy, potentially impacting downstream services. | |||||
| CVE-2025-2784 | 2 Gnome, Redhat | 21 Libsoup, Codeready Linux Builder, Codeready Linux Builder For Arm64 and 18 more | 2026-06-17 | N/A | 7.0 HIGH |
| A flaw was found in libsoup. The package is vulnerable to a heap buffer over-read when sniffing content via the skip_insight_whitespace() function. Libsoup clients may read one byte out-of-bounds in response to a crafted HTTP response by an HTTP server. | |||||
| CVE-2024-52532 | 1 Gnome | 1 Libsoup | 2026-06-17 | N/A | 7.5 HIGH |
| GNOME libsoup before 3.6.1 has an infinite loop, and memory consumption. during the reading of certain patterns of WebSocket data from clients. | |||||
| CVE-2024-52531 | 1 Gnome | 1 Libsoup | 2026-06-17 | N/A | 6.5 MEDIUM |
| GNOME libsoup before 3.6.1 allows a buffer overflow in applications that perform conversion to UTF-8 in soup_header_parse_param_list_strict. There is a plausible way to reach this remotely via soup_message_headers_get_content_type (e.g., an application may want to retrieve the content type of a request or response). | |||||
| CVE-2024-52530 | 1 Gnome | 1 Libsoup | 2026-06-17 | N/A | 7.5 HIGH |
| 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. | |||||
| CVE-2019-17266 | 2 Canonical, Gnome | 2 Ubuntu Linux, Libsoup | 2026-06-17 | 7.5 HIGH | 9.8 CRITICAL |
| libsoup from versions 2.65.1 until 2.68.1 have a heap-based buffer over-read because soup_ntlm_parse_challenge() in soup-auth-ntlm.c does not properly check an NTLM message's length before proceeding with a memcpy. | |||||
| CVE-2018-12910 | 5 Canonical, Debian, Gnome and 2 more | 9 Ubuntu Linux, Debian Linux, Libsoup and 6 more | 2026-06-17 | 7.5 HIGH | 9.8 CRITICAL |
| The get_cookies function in soup-cookie-jar.c in libsoup 2.63.2 allows attackers to have unspecified impact via an empty hostname. | |||||
| CVE-2018-11713 | 2 Gnome, Webkitgtk | 2 Libsoup, Webkitgtk\+ | 2026-06-17 | 4.3 MEDIUM | 6.5 MEDIUM |
| WebCore/platform/network/soup/SocketStreamHandleImplSoup.cpp in the libsoup network backend of WebKit, as used in WebKitGTK+ prior to version 2.20.0 or without libsoup 2.62.0, unexpectedly failed to use system proxy settings for WebSocket connections. As a result, users could be deanonymized by crafted web sites via a WebSocket connection. | |||||
| CVE-2017-2885 | 3 Debian, Gnome, Redhat | 8 Debian Linux, Libsoup, Enterprise Linux Desktop and 5 more | 2026-06-17 | 7.5 HIGH | 9.8 CRITICAL |
| An exploitable stack based buffer overflow vulnerability exists in the GNOME libsoup 2.58. A specially crafted HTTP request can cause a stack overflow resulting in remote code execution. An attacker can send a special HTTP request to the vulnerable server to trigger this vulnerability. | |||||
| CVE-2012-2132 | 1 Gnome | 1 Libsoup | 2026-06-16 | 5.0 MEDIUM | N/A |
| libsoup 2.32.2 and earlier does not validate certificates or clear the trust flag when the ssl-ca-file does not exist, which allows remote attackers to bypass authentication by connecting with a SSL connection. | |||||
| CVE-2011-2524 | 1 Gnome | 1 Libsoup | 2026-06-16 | 5.0 MEDIUM | N/A |
| Directory traversal vulnerability in soup-uri.c in SoupServer in libsoup before 2.35.4 allows remote attackers to read arbitrary files via a %2e%2e (encoded dot dot) in a URI. | |||||
| CVE-2026-5119 | 2 Gnome, Redhat | 2 Libsoup, Enterprise Linux | 2026-06-09 | N/A | 5.9 MEDIUM |
| A flaw was found in libsoup. When establishing HTTPS tunnels through a configured HTTP proxy, sensitive session cookies are transmitted in cleartext within the initial HTTP CONNECT request. A network-positioned attacker or a malicious HTTP proxy can intercept these cookies, leading to potential session hijacking or user impersonation. | |||||
| CVE-2026-4271 | 2 Gnome, Redhat | 2 Libsoup, Enterprise Linux | 2026-05-19 | N/A | 5.3 MEDIUM |
| A flaw was found in libsoup, a library for handling HTTP requests. This vulnerability, known as a Use-After-Free, occurs in the HTTP/2 server implementation. A remote attacker can exploit this by sending specially crafted HTTP/2 requests that cause authentication failures. This can lead to the application attempting to access memory that has already been freed, potentially causing application instability or crashes, resulting in a Denial of Service (DoS). | |||||
| CVE-2026-2708 | 2 Gnome, Redhat | 2 Libsoup, Enterprise Linux | 2026-05-04 | N/A | 3.7 LOW |
| A request smuggling vulnerability exists in libsoup's HTTP/1 header parsing logic. The soup_message_headers_append_common() function in libsoup/soup-message-headers.c unconditionally appends each header value without validating for duplicate or conflicting Content-Length fields. This allows an attacker to send HTTP requests containing multiple Content-Length headers with differing values. | |||||
| CVE-2026-2369 | 1 Gnome | 1 Libsoup | 2026-04-28 | N/A | 6.5 MEDIUM |
| A flaw was found in libsoup. An integer underflow vulnerability occurs when processing content with a zero-length resource, leading to a buffer overread. This can allow an attacker to potentially access sensitive information or cause an application level denial of service. | |||||
| CVE-2026-2436 | 2 Gnome, Redhat | 2 Libsoup, Enterprise Linux | 2026-04-21 | N/A | 6.5 MEDIUM |
| A flaw was found in libsoup's SoupServer. A remote attacker could exploit a use-after-free vulnerability where the `soup_server_disconnect()` function frees connection objects prematurely, even if a TLS handshake is still pending. If the handshake completes after the connection object has been freed, a dangling pointer is accessed, leading to a server crash and a Denial of Service. | |||||
