Vulnerability AssessmentAI
| Exploitation | The application must be using Spring AI versions 1.0.0-1.0.9, 1.1.0-1.1.8, or 2.0.0 and must have an active PDF document ingestion pathway - this vulnerability is specific to PDF processing and does not affect other document types. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | CVSS 7.5 (AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H) accurately reflects a remotely exploitable, low-complexity denial of service. … 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 | Consult the vendor advisory at https://spring.io/security/cve-2026-47851 for the specific patched version; the advisory has been published by VMware/Spring but exact fix version numbers are not independently confirmed in the available intelligence data - do not upgrade to an unconfirmed version. … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours, identify all internal applications using Spring AI versions 1.0.x, 1.1.x, or 2.0.0 and assess their exposure to untrusted PDF inputs. …
