Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

Piwigo 是一款功能齐全、开源的 Web 照片画廊应用程序。在 16.4.0 版本之前，admin/batch_manager.php 接受管理员控制的维度宽度、高度、比例以及文件大小值，这些值通过 Batch Manager（批量管理器）筛选器的 URL 传入，但缺乏数值验证。URL 筛选器解析器将这些值存储到 bulk_manager_filter 会话状态中，随后在构建查询时，会将它们拼接到 SQL 谓词中。这与经过验证的 POST 筛选器路径不同。认证后的管理员可以利用精心构造的筛选值，执行基于时间的

Vulnerability Title
Piwigo: SQL Injection in Batch Manager
Source: CVE Program / CVE List V5
Vulnerability Description
Piwigo is a full featured open source photo gallery application for the web. Prior to 16.4.0, admin/batch_manager.php accepts administrator-controlled dimension width, height, and ratio values and filesize values from the Batch Manager filter URL without numeric validation. The URL filter parser stores those values in the bulk_manager_filter session state, and later query construction concatenates them into SQL predicates, unlike the validated POST filter path. An authenticated administrator can use crafted filter values to execute time-based or other SQL expressions and potentially disclose, modify, or disrupt database data. This issue is fixed in version 16.4.0.
