HIGHNVD 7.87.8—
EchelonGraph scoreMEDIUM confidence

This high-severity CVE scores 7.8 under NVD CVSS v3. EPSS exploit probability: 0.1%, top 98% 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).

ImageMagick before 7.1.2-19 contains an out-of-bounds access vulnerability in ConnectedComponentsImage() when processing connected-components artifacts with invalid indices. Attackers can trigger access violations by specifying malformed connected-components definitions via CLI, causing denial of service or potential code execution.
