  • •SOGo vulnerabilities affect multiple Ubuntu LTS versions, including 18.04 and 26.04.
  • •Critical issues include cross-site scripting and SQL injection vulnerabilities.
  • •Immediate updates are necessary to mitigate risks associated with these vulnerabilities.

Recent vulnerabilities in SOGo have been identified, impacting Ubuntu 18.04 LTS, 20.04 LTS, 22.04 LTS, and 26.04 LTS. The issues include improper sanitization of input leading to potential cross-site scripting (CVE-2025-71276, CVE-2026-3054) and SQL injection vulnerabilities (CVE-2026-46445, CVE-2026-46446). Additionally, a flaw allows remote attackers to bypass authentication due to issues with one-time password management (CVE-2026-33550). These vulnerabilities could allow attackers to execute arbitrary code or gain unauthorized access. Users are advised to update their systems to the latest package versions to mitigate these risks. The vulnerabilities were disclosed in a security notice by Ubuntu on July 5, 2026.
