CVE-2021-33190 is a medium-severity vulnerability rated 5.3/10 on the CVSS scale. In Apache APISIX Dashboard version 2.6, we changed the default value of listen host to 0.0.0.0 in order to facilitate users to configure external network access. In the IP allowed list restriction, a risky function was used for the IP acquisition, which made it possible to bypass the network limit. EPSS estimates a 2.69% chance of exploitation in the next 30 days.
