NVD description
JetLinks Community through 2.10.0 contains a missing authorization vulnerability that allows users with only query access on transparent-codec to overwrite product codecs via POST /device/transparent-codec/{productId}. Because the endpoint lacks @SaveAction, attackers can save arbitrary codec providers and configurations, controlling how transparent messages are decoded and encoded for every device of that product.
