EchelonGraph scoreMEDIUM confidence

This high-severity CVE scores 8.5 under a secondary CVSS source (NVD's own analysis pending). EPSS exploit probability: 1.0%, top 41% 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.

A stored OS command injection vulnerability exists in the parent-control module of TP-Link Archer BE3600 V1. An authenticated adjacent attacker with administrative access may store a crafted profile name containing shell metacharacters, which is later processed unsafely during daily cloud report generation and may result in arbitrary command execution.

Successful exploitation may allow command execution on the affected device with potential impact to device confidentiality, integrity, and availability.
