Piwigo is a full featured open source photo gallery application for the web. In Piwigo 15.6.0, using the password reset function allows sending a password-reset URL by entering an existing username or email address. However, the hostname used to construct this URL is taken from the HTTP request's Host header and is not validated at all. Therefore, an attacker can send a password-reset URL with a modified hostname to an existing user whose username or email the attacker knows or guesses. This issue has been patched in version 15.7.0.
Piwigo 13.8.0 and below is vulnerable to SQL Injection in the parameters max_level and min_register. These parameters are used in ws_user_gerList function from file include\ws_functions\pwg.users.php and this same function is called by ws.php file at some point can be used for searching users in advanced way in /admin.php?page=user_list.
A stored cross-site scripting (XSS) vulnerability in the Configuration page of Piwigo v14.5.0 allows attackers to execute arbitrary web scripts or HTML via a crafted payload injected into the Page banner parameter.
A cross-site scripting (XSS) vulnerability in the component /admin.php?page=album of Piwigo v14.5.0 allows attackers to execute arbitrary web scripts or HTML via a crafted payload injected into the Description field.
A cross-site scripting (XSS) vulnerability in the component /admin.php?page=photo of Piwigo v14.5.0 allows attackers to execute arbitrary web scripts or HTML via a crafted payload injected into the Description field.
An authenticated cross-site scripting (XSS) vulnerability in Piwigo v14.5.0 allows attackers to execute arbitrary web scripts or HTML via a crafted payload injected into the Album Name parameter under the Add Album function.
A Cross Site Scripting vulnerability exists in Piwigo before 14.3.0 script because of missing sanitization in create_tag in admin/include/functions.php.
An issue exists within Piwigo before v.14.2.0 allowing a malicious user to take over the application. This exploit involves chaining a Cross Site Request Forgery vulnerability to issue a Stored Cross Site Scripting payload stored within an Admin user's dashboard, executing remote JavaScript. This can be used to upload a new PHP file under an administrator and directly call that file from the victim's instance to connect back to a malicious listener.
Cross Site Scripting vulnerability in piwigo v.14.0.0 allows a remote attacker to obtain sensitive information via the lang parameter in the Admin Tools plug-in component.
