HOL Guard separates source facts from reviewed analysis. See the methodology.
CVSS is 9.3. The current sources do not mark it as known exploited. Treat this as a source-backed prioritization signal, not a statement about your environment.

OS command injection in the Studio Space startup validation script in Amazon SageMaker Distribution 2.x before 2.14.12, 3.x before 3.9.12, 4.0.x before 4.0.11, 4.1.x before 4.1.11, 4.2.x before 4.2.8, 4.3.x before 4.3.5, and 4.4.x before 4.4.3, as used by Amazon SageMaker Unified Studio, might allow an authenticated remote user with project contributor permissions to execute arbitrary commands in another project member's Studio Space and obtain that member's temporary execution role credentials via a crafted connection resource property that is interpolated into a shell invocation without neutralization. To remediate this issue, users should upgrade to version 2.14.12, 3.9.12, 4.0.11, 4.1.11, 4.2.8, 4.3.5, or 4.4.3, as applicable to the minor line in use. Users on minor lines that have reached end of support must move to a supported minor line, because no patched version will be released for those lines. In Amazon SageMaker Unified Studio, Studio Spaces adopt the latest patch of their minor line on restart once the patched images are deployed, so no version selection is required.
