Description specifies local attacker on multi-user host (AV:L, PR:L); deterministic path requires no special timing (AC:L); model substitution corrupts the application's AI pipeline, crossing trust boundary (S:C, I:H).

DescriptionCVE.org

A local attacker on a multi-user host can pre-create the deterministic cache path and plant a malicious ONNX model file. Spring AI 2.0.0 Spring AI 1.1.0 - 1.1.8 Spring AI 1.0.0 - 1.0.9

AnalysisAI

Predictable ONNX model cache path creation in Spring AI enables a local attacker on a shared multi-user host to pre-create the cache location and substitute a malicious ONNX model before the application writes its legitimate copy. Affected versions span Spring AI 1.0.0-1.0.9, 1.1.0-1.1.8, and 2.0.0. …

Vulnerability AssessmentAI

Exploitation Exploitation requires the attacker to hold an active, low-privileged local account on the same host as the Spring AI application - remote or anonymous exploitation is not consistent with the vulnerability description, despite the conflicting CVSS AV:N vector. … Additional conditions and limiting factors are described in the full assessment.
Risk Assessment The most significant risk signal here is the conflict between the provided CVSS vector (AV:N/AC:L/PR:N/UI:N, implying unauthenticated network exploitation) and the description, which explicitly states a local attacker on a multi-user host - these are irreconcilable, and the discrepancy must be resolved against the vendor advisory before teams make patch prioritization decisions. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in.
Exploit Scenario Full exploit scenario with step-by-step reproduction available after sign-in.
Remediation Upgrade Spring AI to the first version beyond the affected range in your branch - the vendor advisory at https://spring.io/security/cve-2026-47852 should be consulted for the confirmed fixed version numbers, as exact patched releases are not independently confirmed from the available input data. … Detailed patch versions, workarounds, and compensating controls in full report.

Recommended ActionAI

Within 24 hours, inventory all systems running affected Spring AI versions (1.0.0-1.0.9, 1.1.0-1.1.8, 2.0.0) and prioritize those deployed on multi-user or shared systems. …
