Name of the Vulnerable Software and Affected Versions EduSoho versions prior to 22.4.7

Description EduSoho is affected by an arbitrary file read issue in the classroom-course-statistics export functionality. An unauthenticated attacker can potentially read arbitrary files from the server filesystem by supplying crafted path traversal sequences in the fileNames[] parameter. This could include sensitive application configuration files like config/parameters.yml, potentially exposing secrets and database credentials. The Shadowserver Foundation observed exploitation of this issue on 2026-01-19 (UTC).

Recommendations Update EduSoho to version 22.4.7 or later.
