affected by multiple vulnerabilities as referenced in the USN-8504-1 advisory.

    It was discovered that SOGo did not properly sanitize categories used for events, tasks, and contacts. A
    remote authenticated attacker could possibly use this issue to perform cross-site scripting attacks. This
    issue only affected Ubuntu 18.04 LTS, Ubuntu 20.04 LTS, Ubuntu 22.04 LTS, and Ubuntu 26.04 LTS.
    (CVE-2025-71276)

    It was discovered that SOGo did not properly sanitize the hint query parameter. A remote attacker could
    possibly use this issue to perform cross-site scripting attacks. This issue only affected Ubuntu 26.04
    LTS. (CVE-2026-3054)

    It was discovered that SOGo did not renew the one-time password when a user disabled and re-enabled it,
    and used a shorter length than recommended. A remote attacker could possibly use this issue to bypass
    authentication. This issue only affected Ubuntu 22.04 LTS and Ubuntu 26.04 LTS. (CVE-2026-33550)

    It was discovered that SOGo did not properly use the SQL adaptor for the user source, resulting in SQL
    injection when certain databases were used. A remote authenticated attacker could possibly use this issue
    to obtain sensitive information or execute arbitrary SQL commands. (CVE-2026-46445, CVE-2026-46446)

    It was discovered that SOGo did not properly sanitize mail containing ICS calendar invitations. A remote
    attacker could possibly use this issue to perform cross-site scripting attacks. This issue only affected
    Ubuntu 26.04 LTS. (CVE-2026-8496)

    It was discovered that SOGo did not properly validate identifiers when managing access control lists. A
    remote authenticated attacker could possibly use this issue to perform SQL injection attacks and obtain
    sensitive information. (CVE-2026-8851)

    It was discovered that SOGo did not properly sanitize the theme parameter. A remote attacker could
    possibly use this issue to perform cross-site scripting attacks. This issue only affected Ubuntu 18.04
    LTS, Ubuntu 20.04 LTS, and Ubuntu 22.04 LTS. (CVE-2025-63499)

    It was discovered that SOGo did not properly sanitize the userName parameter on the login page. A remote
    attacker could possibly use this issue to perform cross-site scripting attacks. This issue only affected
    Ubuntu 16.04 LTS, Ubuntu 18.04 LTS, Ubuntu 20.04 LTS, and Ubuntu 22.04 LTS. (CVE-2025-63498)

    It was discovered that SOGo did not properly sanitize attachments when previewing them. A remote attacker
    could possibly use this issue to perform cross-site scripting attacks. This issue only affected Ubuntu
    16.04 LTS, Ubuntu 18.04 LTS, Ubuntu 20.04 LTS, and Ubuntu 22.04 LTS. (CVE-2024-34462)

    It was discovered that SOGo did not validate the signatures of SAML assertions it received when SAML was
    used for authentication. A remote attacker could possibly use this issue to impersonate other users. This
    issue only affected Ubuntu 16.04 LTS, Ubuntu 18.04 LTS, and Ubuntu 20.04 LTS. (CVE-2021-33054)
