CVE-2020-29509: Golang Go

Medium severity, CVSS 5.6. EPSS: 2.1% chance of exploitation in the next 30 days.

The encoding/xml package in Go (all versions) does not correctly preserve the semantics of attribute namespace prefixes 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.

Affected products

• Golang Go: before 1.17 (fixed in 1.17)
• Netapp Trident: affected versions not specified
