A remote attacker could exploit an unsigned to signed conversion error in the `soup_body_input_stream_read_chunked()` function by sending a malicious HTTP request. This vulnerability occurs when libsoup operates behind a non-libsoup proxy server or as a proxy in front of a non-libsoup backend server. Successful exploitation can allow an attacker to bypass security controls, poison web caches, or gain unauthorized access.","epss":{"date":"2026-11-02","percentile":0.58898,"score":0.00872},"exploits":[{"kind":"exploit","source":"ADP: CISA-ADP","url":"https://gitlab.gnome.org/GNOME/libsoup/-/work_items/508"}],"kev":null,"metrics":[{"score":4.8,"severity":"medium","source":"CNA: redhat","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:L/I:L/A:N","version":"3.1"}],"modifiedAt":1793672625877,"publishedAt":1780032247364,"references":[{"source":"CNA: redhat","tags":["vdb-entry","x_refsource_REDHAT"],"url":"https://access.redhat.com/security/cve/CVE-2026-6324"},{"source":"CNA: redhat","tags":["issue-tracking","x_refsource_REDHAT"],"url":"https://bugzilla.redhat.com/show_bug.cgi?id=2458479"},{"source":"CNA: redhat","tags":[],"url":"https://gitlab.gnome.org/GNOME/libsoup/-/commit/96ac392b444d01bd5de1d1276b187c3ed49d048c"},{"source":"CNA: redhat","tags":[],"url":"https://gitlab.gnome.org/GNOME/libsoup/-/issues/508"},{"source":"ADP: CISA-ADP","tags":["exploit"],"url":"https://gitlab.gnome.org/GNOME/libsoup/-/work_items/508"}],"remediation":[],"revision":"cddfa8f79d5deae3dfb28deb25c596a67249fe683f499243d5a8c1d11fbd8856","sources":[{"modifiedAt":1793672625877,"name":"CNA: redhat","retrievedAt":1793675302757,"url":"https://www.cve.org/CVERecord?id=CVE-2026-6324"},{"modifiedAt":null,"name":"FIRST EPSS","retrievedAt":1793675304312,"url":"https://api.first.org/data/v1/epss?cve=CVE-2026-6324"}],"ssvc":{"assessedAt":1780063240782,"automatable":"no","exploitation":"poc","source":"ADP: CISA-ADP","technicalImpact":"partial"},"status":"published","title":"Libsoup: libsoup: http request smuggling via unsigned to signed conversion error","updatedAt":1793675304312}
