CVE-2026-89110
Raw vector
CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:HCVSS and EPSS are reproduced from their sources (NVD, FIRST EPSS). Risk Priority is our own derived reading, not an NVD score.
Summary
CVE-2026-89110 is a critical-severity Exposed Dangerous Method or Function (CWE-749) vulnerability in Sap (inferred from references). Its CVSS base score is 9.9 (Critical).
Operationally, exploitation aligns with the MITRE ATT&CK technique Junk Data (T1001.001); ranked at the 22th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog.
The strongest mitigations our analysis identified map to AC-3 (Access Enforcement) and AC-6 (Least Privilege) — see the control section below for these in your framework.

V8.2.1
Mitigating Controls (NIST 800-53 r5) AI
Access enforcement directly stops unauthorized callers from invoking dangerous API methods or functions.
Least privilege restricts which users or processes may reach dangerous methods, limiting exposure.
Least functionality removes or disables non-essential dangerous methods from the exposed interface altogether.
Mitigating Controls (NIST CSF 2.0) AI
Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→CSF cross-walk (authority under review) — links open the control.
Vulnerability identification processes will surface exposed dangerous methods during assessment.
Enforcing least-privilege authorization directly prevents unrestricted dangerous API methods.
Logical access controls at the network/environment layer can limit reachability of exposed functions.
Secure SDLC practices stop developers from exposing dangerous functions in the first place.
