Slow Mist: ReachMe used to have a message fee bypass vulnerability, allowing users to send messages to CZ at a low cost

According to BlockBeats, on March 28th, the SlowMist security team recently revealed a logical vulnerability in ReachMe io, a paid chat platform under the BNB Chain ecosystem, which can bypass the preset fee mechanism and send messages to any KOL (including CZ) at a very low cost. The researchers successfully sent a message to CZ at 0.01 BNB, bypassing the originally set 1 BNB message fee. The vulnerability originated from the contract not verifying the consistency between the on chain transfer amount and the front-end set price. Currently, this vulnerability has been promptly fixed.
