CVE-2026-66775: SAP Approuter

Medium severity, CVSS 4.3. EPSS: 0.2% chance of exploitation in the next 30 days.

SAP Approuter does not enforce cross-site request forgery protection on the authentication flow by default. An unauthenticated attacker could craft a malicious link and trick a victim into following it. Successful exploitation could allow the attacker to bind the victim's session to an attacker-controlled identity, resulting in a low impact on integrity. There is no impact on confidentiality and availability.

Affected products
