CVE-2026-39276Public exploitNetwork attack vector

Authenticated code execution via unsafe template extraction

Published May 29, 2026 · Updated May 29, 2026

Path traversal in Emlog Pro 2.6.9 allows remote authenticated users with administrator access to execute arbitrary PHP code via a template ZIP. The emUnZip path in admin/template.php and include/lib/common.php checks only for header.php, then extractTo writes unvalidated archive entry names outside the template directory. Administrator access to the template installer is required; a crafted ../ entry can overwrite a live PHP template, and a frontend request executes it.
