Heap-based buffer overflow in Tenda AC8V4 router firmware V16.03.34.06 allows unauthenticated remote attackers to corrupt heap memory via a crafted `mac` parameter sent to the `/goform/GetParentControlInfo` endpoint. The vulnerability requires no authentication or user interaction and is reachable over the network, making it exploitable against any device whose web management interface is accessible. A publicly available proof-of-concept exists on GitHub, and the EPSS score of 5.54% at the 92nd percentile indicates elevated real-world exploitation probability relative to the broader CVE population; no public exploit identified at time of analysis confirms CISA KEV listing.
