Piwigo is an open source photo gallery application for the web. Prior to version 16.3.0, the pwg.history.search API method in Piwigo is registered without the admin_only option, allowing unauthenticated users to access the full browsing history of all gallery visitors. This issue has been patched in version 16.3.0.
