EchelonGraph scoreMEDIUM confidence

This high-severity CVE scores 8.7 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).

Scriban before 7.2.0 contains a denial of service vulnerability in the array.insert_at function that allocates unbounded null entries without respecting LoopLimit or LimitToString constraints. Attackers can supply a large index parameter to trigger OutOfMemoryException and crash the host process in under a second.
