CVE-2020-29510 is a medium-severity vulnerability rated 5.6/10 on the CVSS scale. The encoding/xml package in Go versions 1.15 and earlier does not correctly preserve the semantics of directives during tokenization round-trips, which allows an attacker to craft inputs that behave in conflicting ways during different stages of processing in affected downstream applications.. EPSS estimates a 2.05% chance of exploitation in the next 30 days.
