Who should care

Defenders responsible for SparkyFitness instances, especially those with global administrator access, should assess exposure and prioritize upgrading to version 1.6.0 or later. This includes operators, platform administrators, vulnerability management teams, and security teams who need to verify exposure and implement necessary mitigations.

Why it matters

CVE-2026-92263 allows authenticated global administrators to execute arbitrary operating-system commands, potentially disrupting SparkyFitness services and impacting data integrity and confidentiality. Defenders should verify exposure and prioritize upgrading to version 1.6.0 or later.

• Potential execution of arbitrary operating-system commands with server process privileges
• Possible disruption of SparkyFitness services
• Need for verification of exposure and upgrade to patched version
• Potential impact on data integrity and confidentiality

Technical summary

The SparkyFitness application has a vulnerability in the api/admin/backup/restore endpoint, allowing an authenticated global administrator to execute arbitrary operating-system commands with server process privileges by uploading a restore archive with a crafted filename. This issue is fixed in version 1.6.0. Successful exploitation can execute arbitrary operating-system commands with the server process privileges. The administrator can supply a restore archive with a filename containing shell metacharacters.
