CVE-2026-42324 Details
Description
Piwigo is a full featured open source photo gallery application for the web. Prior to 16.4.0, admin/element_set_ranks.php stores administrator-controlled image_order[] values without enforcing the existing sort-field whitelist. The stored album image_order expression is later concatenated into ORDER BY clauses by admin/batch_manager_global.php, admin/batch_manager_unit.php, include/section_init.inc.php, and include/ws_functions/pwg.categories.php. When at least one album contains at least one photo, an authenticated administrator can store a crafted expression and trigger it in a later album or Batch Manager query to disclose, modify, or disrupt database data. This issue is fixed in version 16.4.0.
A second-order SQL injection vulnerability has been identified in Piwigo versions prior to 16.4.0. The issue arises in the album sort order management within the 'admin/element_set_ranks.php' file. User-supplied input is stored without proper validation, allowing an authenticated administrator to inject malicious SQL that is later executed, potentially leading to unauthorized data access or manipulation. The vulnerability is exploited by injecting SQL through the 'image_order' parameter, which is then executed as part of SQL queries related to album management.
The vulnerability has been fixed in Piwigo version 16.4.0. Users are advised to update to this version.
