EchelonGraph scoreMEDIUM confidence

This critical-severity CVE scores 9.4 under a secondary CVSS source (NVD's own analysis pending). EPSS exploit probability: 0.4%, top 72% 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.

Autel Maxi Charger Single firmware through V1.03.51 contains a heap-based buffer overflow in the set_ap_param command handled by the /localcfg endpoint. An authenticated attacker can supply oversized input, resulting in denial of service and potentially arbitrary code execution.
