HIGHPre-NVD 8.38.3—
EchelonGraph scoreMEDIUM confidence

This high-severity CVE scores 8.3 under a secondary CVSS source (NVD's own analysis pending). EPSS exploit probability: 0.3%, top 82% of all CVEs by exploit prediction. GitHub Security Advisory data not yet ingested — confidence will rise once GHSA publishes (typical lag: hours to days for open-source ecosystem CVEs; never for infrastructure-only CVEs).

Nuclio is a "Serverless" framework for Real-Time Events and Data Processing. Prior to version 1.16.0, there is a vulnerability in Nuclio Dashboard's project management API, allowing any authenticated user (without membership in the target project) to bypass OPA authorization checks on write paths (PUT /api/projects/{id}, DELETE /api/projects) and modify or delete any project along with all its associated resources (functions, API gateways, etc.). This issue has been patched in version 1.16.0.
