    Multiple vulnerabilities were discovered in sogo, the open-source     webmail and groupware server:

    * CVE-2026-46445: A SQL injection vulnerability when PostgreSQL is       used as the user database.

    * CVE-2026-46446: Address a SQL injection vulnerability when MariaDB       or PostgreSQL is used as the user database and passwords are       stored in cleartext.

    * CVE-2025-71276: Fix a A Cross-Site Scripting (XSS) vulnerability in       events, tasks and contacts categories.

    * CVE-2026-33550: Address a number of Time-Based One-Time Passwords       (TOTP) vulnerabilities, including if a user disables/enables TOTP,       various values not being renewed, and an issue around recommended       TOTP lengths.

    * CVE-2026-8496: Fix an issue where a maliciously crafted .ICS       calendar invitation file allowed arbitrary JavaScript execution       within an authenticated webmail session.

    * CVE-2026-8851: Fix an SQL injection vulnerability in the access       control list management functionality, which could have allowed       authenticated users to extract arbitrary data from the database by       injecting SQL subqueries through the uid parameter of the       addUserInAcls endpoint.

    In addition, a patch was added to fix a Cross-Site Scripting (XSS)     vulnerability in message subject rendering.

    For Debian 11 bullseye, these problem have been fixed in version     5.8.0-2+deb12u3.

    We recommend that you upgrade your sogo packages.

Tenable has extracted the preceding description block directly from the Debian security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

The remote Ubuntu 16.04 LTS / 18.04 LTS / 20.04 LTS / 22.04 LTS / 26.04 LTS host has packages installed that are 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 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)

Tenable has extracted the preceding description block directly from the Ubuntu security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - SOGo before 5.12.5 does not renew the OTP if a user disables/enables it, and has a too short length (only     12 digits instead of the 20 recommended). (CVE-2026-33550)

Note that Nessus relies on the presence of the package as reported by the vendor.

The remote Debian 13 host has packages installed that are affected by multiple vulnerabilities as referenced in the dsa-6366 advisory.
