EchelonGraph scoreMEDIUM confidence

This high-severity CVE scores 8.4 under NVD CVSS v3. EPSS exploit probability: 0.4%, top 71% 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).

No vendor fix yet — apply a workaround or compensating control (WAF / firewall / segmentation) and watch for a patch.

Maple versions up to and including 13's Maplet framework allows embedded commands to be executed automatically when a .maplet file is opened. This behavior bypasses standard security restrictions that normally prevent code execution in regular Maple worksheets. The vulnerability enables attackers to craft malicious .maplet files that execute arbitrary code without user interaction.
