A threat actor is allegedly selling Docker container escape on a dark web forum. According to the post on the forum, this allows an attacker to escape the container environment to the host system. It is also stated that a previous vulnerability published by the same threat actor can be chained with this exploit.
The threat actor indicated that the alleged vulnerability was tested on v-20.10.(20-25) versions and the tested kernel version was 6.8.11.
The post mentions that the price is $69,000 USD.
