An attacker may leverage this issue to execute arbitrary script code in the browser of an unsuspecting user in the context of the affected site. This can allow the attacker to steal cookie-based authentication credentials and launch other attacks.
Stefan Schurtz has discovered a vulnerability in Piwigo, which can be exploited by malicious people to conduct cross-site scripting attacks.
Input passed via the "username_or_email" parameter to password.php is not properly sanitised in themes/default/template/password.tpl before being returned to the user. This can be exploited to execute arbitrary HTML and script code in a user's browser session in context of an affected site. The vulnerability is confirmed in versions 2.4.3 and 2.4.4. Other versions may also be affected.
