CVE-2026-89120
Raw vector
CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:H/A:NCVSS and EPSS are reproduced from their sources (NVD, FIRST EPSS). Risk Priority is our own derived reading, not an NVD score.
Summary
CVE-2026-89120 is a high-severity Initialization of a Resource with an Insecure Default (CWE-1188) vulnerability in Sap (inferred from references). Its CVSS base score is 7.1 (High).
Operationally, exploitation aligns with the MITRE ATT&CK technique Protocol or Service Impersonation (T1001.003); ranked at the 14th 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-6 (Least Privilege) and CM-2 (Baseline Configuration) — see the control section below for these in your framework.

Mitigating Controls (NIST 800-53 r5) AI
Least privilege reduces the blast radius of any insecure default permissions that remain after initialization.
Baseline configuration directly requires documenting and maintaining secure initial settings instead of insecure defaults.
Configuration settings mandate the most restrictive values be applied at initialization, eliminating reliance on insecure factory defaults.
Security engineering principles include explicit requirements for secure defaults during resource initialization and design.

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.
Pre-acquisition integrity checks can reject products known to ship with insecure defaults.
Hardened baselines and configuration management directly replace insecure defaults with secure settings.
Secure development practices include designing products with secure defaults rather than insecure ones.
