An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-1801 in the wild and no public exploit code.\n\nAffected product: Redhat Enterprise Linux. No package-level version data is available, so check the vendor advisory linked from the reference page.\n\nTask:\n1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.\n2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.\n3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.\n4. Run the tests and summarise what changed and why.\n5. If nothing in the project is affected, say so and change nothing.\n\nReference: https://insights.sbomify.com/CVE-2026-1801/ (Markdown: https://insights.sbomify.com/CVE-2026-1801/index.md)","id":"CVE-2026-1801","markdown":"https://insights.sbomify.com/CVE-2026-1801/index.md","name":"CVE-2026-1801","record":{"aliases":["AZL-76700","AZL-76736","DEBIAN-CVE-2026-1801","ECHO-47e4-5b68-7dd8","GHSA-xv49-34rf-rqv4","SUSE-SU-2026:22061-1","SUSE-SU-2026:22071-1","SUSE-SU-2026:2654-1","SUSE-SU-2026:2670-1","SUSE-SU-2026:2702-1","UBUNTU-CVE-2026-1801","openSUSE-SU-2026:10917-1","openSUSE-SU-2026:20895-1"],"analysis":{"component_type":"library","fix_type":"patch","impacts":["data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"HTTP client/server library","requires_auth":"none","summary":"Remote attackers can exploit HTTP request smuggling in libsoup via malformed chunk headers to potentially disclose sensitive information.","user_interaction":"not_required","vuln_class":"other"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"redhat","cpe":[{"product":"libsoup","vendor":"gnome"},{"product":"enterprise_linux","vendor":"redhat"}],"cvss":{"score":5.3,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:N","version":"3.1"},"cwes":[{"id":"CWE-444","name":"Inconsistent Interpretation of HTTP Requests"}],"description":"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.","ecosystems":["SUSE:Linux Enterprise Micro 5.3","SUSE:Linux Enterprise Micro 5.4","SUSE:Linux Enterprise Micro 5.5","SUSE:Linux Enterprise Module for Basesystem 15 SP7","SUSE:Linux Enterprise Server LTSS Extended Security 12 SP5","SUSE:Linux Micro 6.0","SUSE:Linux Micro 6.1","openSUSE:Tumbleweed"],"exploits":{"exploitdb":0,"first_seen":"2026-08-29","github_poc":1,"max_poc_stars":0,"metasploit":0,"nuclei":0,"refs":[{"date":"2026-08-29T23:38:23Z","kind":"github_poc","ref":"https://github.com/misterdengi/CVE-2026-1801C","stars":0,"title":null}],"tier":"poc_unverified"},"has_fix":true,"headline":"Libsoup: libsoup: http request smuggling via malformed chunk headers","id":"CVE-2026-1801","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"redhat:enterprise_linux","products":["redhat:enterprise_linux"],"type":"other","year":"2026"},"n_packages":8,"n_references":3,"next":{"headline":"Ziroom ZHOME A0101 zrMacClone.lua macAddrClone command injection","id":"CVE-2026-1802"},"packages":[{"ecosystem":"SUSE:Linux Enterprise Micro 5.3","fixed":["2.74.2-150400.3.37.1"],"introduced":["0"],"last_affected":[],"package":"libsoup2","purl":"pkg:rpm/suse/libsoup2\u0026distro=SUSE%20Linux%20Enterprise%20Micro%205.3","source":"SUSE-SU-2026:2670-1"},{"ecosystem":"SUSE:Linux Enterprise Micro 5.4","fixed":["2.74.2-150400.3.37.1"],"introduced":["0"],"last_affected":[],"package":"libsoup2","purl":"pkg:rpm/suse/libsoup2\u0026distro=SUSE%20Linux%20Enterprise%20Micro%205.4","source":"SUSE-SU-2026:2670-1"},{"ecosystem":"SUSE:Linux Enterprise Micro 5.5","fixed":["2.74.2-150400.3.37.1"],"introduced":["0"],"last_affected":[],"package":"libsoup2","purl":"pkg:rpm/suse/libsoup2\u0026distro=SUSE%20Linux%20Enterprise%20Micro%205.5","source":"SUSE-SU-2026:2670-1"},{"ecosystem":"SUSE:Linux Enterprise Module for Basesystem 15 SP7","fixed":["2.74.3-150600.4.36.1"],"introduced":["0"],"last_affected":[],"package":"libsoup2","purl":"pkg:rpm/suse/libsoup2\u0026distro=SUSE%20Linux%20Enterprise%20Module%20for%20Basesystem%2015%20SP7","source":"SUSE-SU-2026:2654-1"},{"ecosystem":"SUSE:Linux Enterprise Server LTSS Extended Security 12 SP5","fixed":["2.62.2-5.43.1"],"introduced":["0"],"last_affected":[],"package":"libsoup","purl":"pkg:rpm/suse/libsoup\u0026distro=SUSE%20Linux%20Enterprise%20Server%20LTSS%20Extended%20Security%2012%20SP5","source":"SUSE-SU-2026:2702-1"},{"ecosystem":"SUSE:Linux Micro 6.0","fixed":["3.4.2-16.1"],"introduced":["0"],"last_affected":[],"package":"libsoup","purl":"pkg:rpm/suse/libsoup\u0026distro=SUSE%20Linux%20Micro%206.0","source":"SUSE-SU-2026:22061-1"},{"ecosystem":"SUSE:Linux Micro 6.1","fixed":["3.4.4-slfo.1.1_10.1"],"introduced":["0"],"last_affected":[],"package":"libsoup","purl":"pkg:rpm/suse/libsoup\u0026distro=SUSE%20Linux%20Micro%206.1","source":"SUSE-SU-2026:22071-1"},{"ecosystem":"openSUSE:Tumbleweed","fixed":["2.74.3-21.1"],"introduced":["0"],"last_affected":[],"package":"libsoup2","purl":"pkg:rpm/opensuse/libsoup2\u0026distro=openSUSE%20Tumbleweed","source":"openSUSE-SU-2026:10917-1"}],"prev":{"headline":"Fonts Manager | Custom Fonts \u003c= 1.2 -
