| CVE-2026-66777 | Med | 0.38 | 5.9 | 0.00 | Aug 11, 2026 | 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… | ||
| CVE-2026-66776 | Med | 0.38 | 5.9 | 0.00 | Aug 11, 2026 | SAP Approuter does not consistently enforce integrity verification on certain session-related request headers under specific conditions. An attacker with low privileges could send a specially crafted request that bypasses the integrity check and loads another user's session… | ||
| CVE-2026-58238 | Med | 0.38 | 5.9 | 0.00 | Aug 11, 2026 | SAP Approuter does not sufficiently handle certain requests under specific conditions. An unauthenticated attacker could send specially crafted input that causes the component to crash and restart. Successful exploitation requires specific runtime conditions to be met, making… | ||
| CVE-2026-58237 | Med | 0.38 | 5.9 | 0.00 | Aug 11, 2026 | WebSocket of SAP Approuter does not perform sufficient authorization checks in certain functionality.

| CVE-2026-66778 | Med | 0.34 | 5.3 | 0.00 | Aug 11, 2026 | SAP Approuter does not sufficiently sanitize certain request headers before forwarding traffic to internal components. An unauthenticated attacker could send a specially crafted request to obtain limited unauthorized access to information. This results in a low impact on… | ||
| CVE-2026-66775 | Med | 0.28 | 4.3 | 0.00 | Aug 11, 2026 | 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… | ||
| CVE-2026-66761 | Med | 0.28 | 4.3 | 0.00 | Aug 11, 2026 | SAP Approuter does not enforce sufficient flow control in certain functionality. An attacker with low privileges could send high volumes of data without consuming responses, causing unbounded memory growth. This results in a low impact on availability. There is no impact on… | ||
| CVE-2026-66774 | Low | 0.24 | 3.7 | 0.00 | Aug 11, 2026 | SAP Approuter does not consistently handle certain error conditions. An attacker with low privileges could exploit this under a non-default configuration. Successful exploitation is highly complex, as it depends on conditions outside the attacker's control. This could result in… | ||
| CVE-2026-58239 | Low | 0.24 | 3.7 | 0.00 | Aug 11, 2026 | SAP Approuter does not sufficiently validate tenant context in inbound requests. An unauthenticated attacker could send specially crafted requests to spoof the tenant context under conditions not fully within their control. Successful exploitation could allow limited access to… |
