7.3 highCVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:LCVE-2021-33195
High (7.3). EPSS 3.2% chance of exploitation in the next 30 days. Fixed in stdlib 1.15.13, 1.16.5.
Go before 1.15.13 and 1.16.x before 1.16.5 has functions for DNS lookups that do not validate replies from DNS servers, and thus a return value may contain an unsafe injection (e.g., XSS) that does not conform to the RFC1035 format.
