# CVE-2026-8619

> 7.1 HIGH

## Beschreibung

An
unauthenticated denial-of-service vulnerability was identified in TP-Link TL-MR100 v3.2, TL-MR150 v3.2, TL-MR6400 v8.0 and Archer MR600 v2, due to improper handling of exceptional request conditions
that may lead to a NULL pointer dereference. 
A remote attacker on an adjacent network can send a specially crated
HTTP request to trigger a crash of the HTTP service process.





Successful
exploitation may cause the HTTP service to crash, making the web management
interface and HTTP-dependent functionality temporarily unavailable.
