CVE-2026-66777
MediumCVSS 5.9Exploitation Probability (EPSS)
Low risk24th percentile - higher than 24% of all known CVEs
Summary
SAP Approuter does not sufficiently validate certain incoming requests before forwarding them to backend destinations. An attacker with low privileges could send specially crafted requests to bypass authorization checks and reach protected resources beyond their assigned scope.
Risk Assessment
Successful exploitation could allow the attacker to read sensitive data and perform limited modifications on protected resources, resulting in a high impact on confidentiality and a low impact on integrity. Availability is unaffected.
Recommendation
Update SAP Approuter and review route configurations and access controls to ensure strict request validation.
