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

Piwigo 是一款功能齐全的开源 Web 照片画廊应用程序。在 17.0.0beta1 及更早版本中，当启用评分功能时，未认证的访客可以通过构造特定的 值调用 接口，并随后访问返回的搜索结果 URL。 在 中，该未经过验证的值被直接存储到搜索规则中；而在 中，仅对下界评分值进行了整型强制转换，而将原始值直接拼接为上界评分值的 SQL 查询条件。 这种缺陷会导致通过公开的搜索流程，利用错误注入或盲注技术提取数据库信息，以及引发依赖数据库的耗时延迟攻击。 截至本次审查时，尚未提供修复该漏洞的版本。

Vulnerability Title
Piwigo: Unauthenticated SQL injection in `pwg.images.filteredSearch.create`
Source: CVE Program / CVE List V5
Vulnerability Description
Piwigo is a full featured open source photo gallery application for the web. In 17.0.0beta1 and earlier, when rating is enabled, an unauthenticated guest can call pwg.images.filteredSearch.create with a crafted ratings[] value and then open the returned search URL. include/ws_functions/pwg.images.php stores the unvalidated value in the search rules, and include/functions_search.inc.php integer-casts only the lower rating bound while concatenating the raw value as the SQL upper bound. This allows error-based or blind extraction of database information and database-dependent time delays through the public search flow. No fixed version is available as of this review.
