WID-SEC-W-2026-3284Drupal Erweiterungen: Mehrere SchwachstellenDeutsch2026-09-09csaf · cert_bundDE
Ein Angreifer kann mehrere Schwachstellen in Drupal ausnutzen, um Datenbankinhalte zu manipulieren oder auszulesen, Zugriffsbeschränkungen und Authentifizierungsmechanismen zu umgehen, vertrauliche Informationen offenzulegen, Cross Site Scripting Angriffe auszuführen, Benutzer auf manipulierte Webseiten umzuleiten, SAML-Authentifizierungen zu beeinflussen oder wiederzuverwenden, interne Ressourcen über SSRF anzusprechen sowie unberechtigt Dateien auf den Server hochzuladen.
DRUPAL-CONTRIB-2026-1432026-09-09vendor · osvUS
This module allows you to configure your Drupal site as a SAML 2.0 Service Provider so that users can authenticate through an external identity provider. The miniorange\_saml module does not sufficiently validate certain user-supplied URLs before performing redirects. An attacker could cause users to be redirected to an external website after authentication. This could be used in phishing attacks or to increase the credibility of malicious links.
