CVE-2026-41655Public exploitNetwork attack vector

Authenticated file disclosure via eCard path traversal

Published May 7, 2026 · Updated May 7, 2026

Path traversal in Admidio before 5.0.9 allows remote authenticated users to read arbitrary server files through eCard preview requests. The ecard_preview.php endpoint strips HTML tags but passes the unverified ecard_template value to ECard::getEcardTemplate(), which concatenates it into an fopen path. A regular member account, a valid eCard form session, and its CSRF token are required; traversal can expose source code, system files, and database credentials.
