CVE-2026-66777Multiple vulnerabilities in SAP Business AI Platform (Approuter)
Medium 5.9
In plain English
A medium-severity path traversal in SAP Business AI Platform (Approuter) from SAP_SE. There are no confirmed reports of exploitation so far. The chance it is exploited in the next 30 days is estimated at 0.4% (higher than 38% of all known vulnerabilities).
Official description
SAP Approuter does not sufficiently validate certain incoming requests before forwarding them to backend destinations. Due to the complexity of the required conditions, an attacker with low privileges could send specially crafted requests to bypass authorization checks and reach protected resources beyond their assigned scope. 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. There is no impact on availability.
