    26.04 LTS. (CVE-2026-4271)

    It was discovered that libsoup incorrectly handled certain HTTPS proxy connections. A remote attacker
    could possibly use this issue to obtain sensitive information. This issue only affected Ubuntu 22.04 LTS,
    Ubuntu 24.04 LTS, and Ubuntu 26.04 LTS. (CVE-2026-5119)

    It was discovered that libsoup incorrectly parsed certain chunked HTTP requests. A remote attacker could
    possibly use this issue to bypass security controls. This issue only affected Ubuntu 22.04 LTS, Ubuntu
    24.04 LTS, and Ubuntu 26.04 LTS. (CVE-2026-6324)

    It was discovered that libsoup incorrectly handled proxy authentication credentials. A remote attacker
    could possibly use this issue to obtain sensitive information. (CVE-2026-66339)

    possibly use this issue to cause a denial of service. (CVE-2026-77014, CVE-2026-77680)

    It was discovered that libsoup incorrectly handled certain HTTP/2 connections. A remote attacker could
    possibly use this issue to obtain sensitive information or execute arbitrary code. This issue only
    affected Ubuntu 22.04 LTS, Ubuntu 24.04 LTS, and Ubuntu 26.04 LTS. (CVE-2026-85197)

    It was discovered that libsoup incorrectly handled certain HTTP/2 transfers. A remote attacker could
    possibly use this issue to cause a denial of service. This issue only affected Ubuntu 22.04 LTS, Ubuntu
