CVE-2021-33195 log

Source
Severity Medium
Remote Yes
Type Insufficient validation
Description
A security issue has been found in Go before version 1.16.5. The LookupCNAME, LookupSRV, LookupMX, LookupNS, and LookupAddr functions in net, and their respective methods on the Resolver type may return arbitrary values retrieved from DNS which do not follow the established RFC 1035 rules for domain names. If these names are used without further sanitization, for instance unsafely included in HTML, they may allow for injection of unexpected content. Note that LookupTXT may still return arbitrary values that could require sanitization before further use.
