The Configuration component of Piwigo 2.9.2 is vulnerable to Persistent Cross Site Scripting via the gallery_title parameter in an admin.php?page=configuration§ion=main request. An attacker can exploit this to hijack a client's browser along with the data stored in it.
Add your gear to cvedb and we'll alert you only when piwigo ships something exploited.
