Does this matter?
EPSS puts the probability of exploitation in the next 30 days at 18.2%, higher than 97% of all known CVEs. Patch or mitigate before the next change window.
Description
Kibana versions 6.7.0 to 6.8.8 and 7.0.0 to 7.6.2 contain a prototype pollution flaw in the Upgrade Assistant. An authenticated attacker with privileges to write to the Kibana index could insert data that would cause Kibana to execute arbitrary code. This could possibly lead to an attacker executing code with the permissions of the Kibana process on the host system.
