Who should care

Administrators and security teams running SOGo Web Calendar, especially where users can create or view shared appointments and contacts.

Technical summary

The vulnerability is categorized as CWE-79 (XSS). The attack surface is the web calendar interface: untrusted content in appointment titles or contact fields can be rendered in a browser and execute in the context of the application. NVD lists the affected CPE range as SOGo up to 2.1.1, while the CVE description states before 2.2.0; both indicate older releases are affected.

Defensive priority

Medium. The issue requires user interaction, but it can affect browser sessions and integrity of rendered content in a collaboration product used by multiple users.

Recommended defensive actions

  • Upgrade SOGo to a version at or beyond the fixed release referenced by the CVE description (2.2.0 or later).
  • Review the vendor advisory and related patch commits for the exact remediation applied to calendar and contact rendering.
  • Verify that calendar titles and contact fields are consistently output-encoded and sanitized before browser rendering.
  • Search for existing malicious or unexpected HTML/script content in stored calendar entries and contacts, then remove or neutralize it.
  • Apply defense-in-depth controls such as restrictive content security policies where practical.

Evidence notes
