CVE-2026-34977Public exploitNetwork attack vector

Unauthenticated root code execution via JPEG password

Published Apr 6, 2026 · Updated Apr 6, 2026

OS command injection in Zeecka Aperi'Solve 3.1.3 through 3.2.0 allows remote attackers to execute code as root in its worker container. The JPSeek analyzer interpolates an upload-form JPEG password into an expect script passed to bash -c without neutralizing shell metacharacters. A single unauthenticated HTTP request can read or alter stored images, results, and passwords; host compromise requires Docker socket or host-volume exposure.
