Realtime 24.04 LTS host has packages installed that are affected by a vulnerability as referenced in the USN-8780-1
advisory.

    It was discovered that libsoup incorrectly handled certain URLs when using an HTTP proxy. A remote
    attacker could possibly use this issue to inject arbitrary HTTP headers. (CVE-2026-1467)

    It was discovered that libsoup did not remove proxy authentication credentials when following HTTP
    redirects. A remote attacker could possibly use this issue to obtain sensitive information.
    (CVE-2026-1539)

    Ahmed Lekssays discovered that libsoup incorrectly parsed certain HTTP requests. A remote attacker could
    possibly use this issue to obtain sensitive information. (CVE-2026-1801)
