CVE-2026-27634

CRITICAL

Piwigo: Pre-auth SQL injection via date filter parameters in ws_std_image_sql_filter

Title source: cna
STIX 2.1

Description

Piwigo is an open source photo gallery application for the web. Prior to version 16.3.0, the four date filter parameters (f_min_date_available, f_max_date_available, f_min_date_created, f_max_date_created) in ws_std_image_sql_filter() are concatenated directly into SQL without any escaping or type validation. This could result in an unauthenticated attacker reading the full database, including user password hashes. This issue has been patched in version 16.3.0.
