The Matomo Analytics – Ethical Stats. Powerful Insights. plugin for WordPress is vulnerable to Reflected Cross-Site Scripting via the idsite parameter in all versions up to, and including, 4.15.3 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that execute if they can successfully trick a user into performing an action such as clicking on a link.
Cross-site Scripting (XSS) in Piwik before 1.10.1 allows remote attackers to inject arbitrary web script or HTML via unspecified vectors. NOTE: This is a different vulnerability than CVE-2013-0194 and CVE-2013-0195.
Cross-site Scripting (XSS) in Piwik before 1.10.1 allows remote attackers to inject arbitrary web script or HTML via unspecified vectors. NOTE: This is a different vulnerability than CVE-2013-0193 and CVE-2013-0195.
Cross-site Scripting (XSS) in Piwik before 1.10.1 allows remote attackers to inject arbitrary web script or HTML via unspecified vectors. NOTE: This is a different vulnerability than CVE-2013-0193 and CVE-2013-0194.
A full path disclosure vulnerability was discovered in Matomo v3.9.1 where a user can trigger a particular error to discover the full path of Matomo on the disk, because lastError.file is used in plugins/CorePluginsAdmin/templates/safemode.twig. NOTE: the vendor disputes the significance of this issue, stating "avoid reporting path disclosures, as we don't consider them as security vulnerabilities.
The DisplayTopKeywords function in plugins/Referrers/Controller.php in Piwik before 2.15.0 allows remote attackers to conduct PHP object injection attacks, conduct Server-Side Request Forgery (SSRF) attacks, and execute arbitrary PHP code via a crafted HTTP header.
