It uses GObjects and the glib main loop, to integrate well with GNOME applications, and also has a synchronous API, for use in threaded applications.\r\n\r\nSecurity Fix(es):\n\nThe fix for CVE-2026-0716 (commit 6ff7ef0, libsoup 3.6.6) placed the integer overflow guard inside the if (masked) block, leaving unmasked server-to-client frames unprotected. A malicious WebSocket server can send a crafted unmasked frame with a payload length near UINT64_MAX to trigger an OOB read in a libsoup-based client when max_incoming_payload_size is set to 0.(CVE-2026-12478)\n\nA 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-2026-2708)","affected":[{"package":{"ecosystem":"openEuler:24.03-LTS-SP4","name":"libsoup","purl":"pkg:rpm/openEuler/libsoup&distro=openEuler-24.03-LTS-SP4"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"2.74.3-24.oe2403sp4"}]}],"ecosystem_specific":{"aarch64":["libsoup-2.74.3-24.oe2403sp4.aarch64.rpm","libsoup-debuginfo-2.74.3-24.oe2403sp4.aarch64.rpm","libsoup-debugsource-2.74.3-24.oe2403sp4.aarch64.rpm","libsoup-devel-2.74.3-24.oe2403sp4.aarch64.rpm"],"noarch":["libsoup-help-2.74.3-24.oe2403sp4.noarch.rpm"],"src":["libsoup-2.74.3-24.oe2403sp4.src.rpm"],"x86_64":["libsoup-2.74.3-24.oe2403sp4.x86_64.rpm","libsoup-debuginfo-2.74.3-24.oe2403sp4.x86_64.rpm","libsoup-debugsource-2.74.3-24.oe2403sp4.x86_64.rpm","libsoup-devel-2.74.3-24.oe2403sp4.x86_64.rpm"]}}],"references":[{"type":"ADVISORY","url":"https://www.openeuler.org/zh/security/security-bulletins/detail/?id=openEuler-SA-2026-3451"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-12478"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-2708"}],"severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:N"}],"database_specific":{"severity":"Medium"}}
